"Understanding ViewBag, ViewData, and TempData in ASP.NET Core MVC: When and How to Use Them"

Azizul Arif — Thu, 05 Sep 2024 19:16:13 +0000

ViewBag

ViewBag is a dynamic object used to pass data from the controller to the view. It’s easy to use but not strongly typed, and it's specific to the current request.
Controller (Index action)

public IActionResult Index()
{
    var villaNumberList = _db.VillaNumberss.ToList();

    // Using ViewBag to pass a simple message
    ViewBag.Message = "Welcome to the Villa Number List page!";

    return View(villaNumberList);
}

View(Index.cshtml):

@model IEnumerable<WhiteLagoon.Domain.Entity.VillaNumber>

<div class="card">
    <div class="card-header text-center">
      <!-- Displaying the ViewBag message -->
        <h3>@ViewBag.Message</h3> 
    </div>
    <div class="card-body">
        <table class="table table-bordered table-striped">
            <thead>
                <tr>
                    <th>Villa Id</th>
                    <th>Villa Number</th>
                    <th>Details</th>
                </tr>
            </thead>
            <tbody>
                @foreach (var item in Model)
                {
                    <tr>
                        <td>@item.Villa_Id</td>
                        <td>@item.Villa_Number</td>
                        <td>@item.SpecialDetails</td>
                    </tr>
                }
            </tbody>
        </table>
    </div>
</div>

ViewData

ViewData is a dictionary object used to pass data between the controller and view. Like ViewBag, it's specific to the current request but is slightly different as it uses key-value pairs.
Controller (Index action)

public IActionResult Index()
{
    var villaNumberList = _db.VillaNumberss.ToList();

    // Using ViewData to pass a simple message
    ViewData["Title"] = "Villa Number List";

    return View(villaNumberList);
}

View (Index.cshtml)

@model IEnumerable<WhiteLagoon.Domain.Entity.VillaNumber>

<div class="card">
    <div class="card-header text-center">
      <!-- Displaying the ViewData value -->
        <h3>@ViewData["Title"]</h3> 
    </div>
    <div class="card-body">
        <table class="table table-bordered table-striped">
            <thead>
                <tr>
                    <th>Villa Id</th>
                    <th>Villa Number</th>
                    <th>Details</th>
                </tr>
            </thead>
            <tbody>
                @foreach (var item in Model)
                {
                    <tr>
                        <td>@item.Villa_Id</td>
                        <td>@item.Villa_Number</td>
                        <td>@item.SpecialDetails</td>
                    </tr>
                }
            </tbody>
        </table>
    </div>
</div>

TempData

Controller (Index action)

public IActionResult Index()
{
    var villaNumberList = _db.VillaNumberss.ToList();

    // Using TempData to pass a message for the next request
    TempData["SuccessMessage"] = "Data retrieved successfully!";

    return View(villaNumberList);
}

View(Index.cshtml)

@model IEnumerable<WhiteLagoon.Domain.Entity.VillaNumber>

<div class="card">
    <div class="card-header text-center">
        <h3>Villa Number List</h3>
        @if (TempData["SuccessMessage"] != null)
        {
            <!-- Displaying TempData message -->
        <div class="alert alert-success">
           @TempData["SuccessMessage"] 
        </div> 
        }
    </div>
    <div class="card-body">
        <table class="table table-bordered table-striped">
            <thead>
                <tr>
                    <th>Villa Id</th>
                    <th>Villa Number</th>
                    <th>Details</th>
                </tr>
            </thead>
            <tbody>
                @foreach (var item in Model)
                {
                    <tr>
                        <td>@item.Villa_Id</td>
                        <td>@item.Villa_Number</td>
                        <td>@item.SpecialDetails</td>
                    </tr>
                }
            </tbody>
        </table>
    </div>
</div>

Key Differences:

ViewBag:

Ideal for passing temporary data in the same request, it is dynamic and
easy to use.

ViewData:

A bit more structured than ViewBag, using a key-value dictionary.

TempData:

Useful for passing data across requests (e.g., after a redirect).

Generics in C# with Practical Examples

Azizul Arif — Mon, 02 Sep 2024 15:33:26 +0000

Generics in C# with Practical Examples

Generics in C# are one of the most powerful features of the language, allowing developers to create flexible and reusable code. By using generics, you can create classes, methods, interfaces, and delegates that work with any data type. This article will walk you through the concept of generics with practical examples, demonstrating how to use both single and multiple generic parameters.

What are Generics?

Generics allow you to define a class, method, or other data structures without committing to a specific data type. This means you can write code that is type-safe yet flexible enough to handle different data types, which reduces redundancy and enhances code reusability.

Single Generic Parameter Example

Let's start with a simple example: a User class that can store a user's registration number. However, instead of tying the class to a specific data type, we use a generic parameter, T, to make it flexible.

using System;

namespace GenericProperty
{
    // Single Generic
    public class User<T>
    {
        public T UserRegistrationNumber { get; set; }
    }
}

n the code above, the User class has a generic property UserRegistrationNumber of type T. This allows us to use the class with any data type.
Let's see it in action:

using System;

namespace GenericClassExample
{
    internal class Program
    {
        static void Main(string[] args)
        {
            User<int> user1 = new User<int>();
            user1.UserRegistrationNumber = 1234;
            Console.WriteLine(user1.UserRegistrationNumber);

            User<string> user2 = new User<string>();
            user2.UserRegistrationNumber = "LA1234";
            Console.WriteLine(user2.UserRegistrationNumber);

            Console.ReadKey();
        }
    }
}

In this example:

user1 is an instance of User, where T is an int.
user2 is an instance of User, where T is a string.
The output will be:

1234
LA1234

This demonstrates how the User class can handle different data types using a single generic parameter.

Multiple Generic Parameters Example
Next, let's explore using multiple generic parameters. We'll create a Survey class that can store both the registration status and age of a person. Since these two properties could be of different types, we'll use two generic parameters: RegStatus and Age.

using System;

namespace GenericProperty
{
    // Multiple Generics
    public class Survey<RegStatus, Age>
    {
        public RegStatus regStatus { get; set; }
        public Age age { get; set; }
    }
}

Now, let's see how to use the Survey class:
using System;

namespace GenericClassExample
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Survey<bool, int> person1 = new Survey<bool, int>();
            person1.regStatus = true;
            person1.age = 22;

            Survey<bool, string> person2 = new Survey<bool, string>();
            person2.regStatus = false;
            person2.age = "22-25";

            Console.WriteLine($"Person1 detail: Reg Status- {person1.regStatus}, Age- {person1.age}");
            Console.WriteLine($"Person2 detail: Reg Status- {person2.regStatus}, Age- {person2.age}");

            Console.ReadKey();
        }
    }
}

In this example:

person1 is an instance of Survey, where RegStatus is a bool and Age is an int.

person2 is an instance of Survey, where RegStatus is a bool and Age is a string.

The output will be:

Person1 detail: Reg Status- True, Age- 22
Person2 detail: Reg Status- False, Age- 22-25

This example highlights how multiple generics can be used to create a versatile and reusable class.

Implementing Toastr Notifications in ASP.NET MVC: A Step-by-Step Guide for Enhanced User Experience"

Azizul Arif — Sat, 31 Aug 2024 16:45:46 +0000

Toastr is a simple yet powerful JavaScript library for displaying notifications to users. In this guide, I'll walk you through how to integrate Toastr into your ASP.NET MVC application, leveraging TempData to show success or error messages based on actions in your controller.

Step 1: Install Toastr

First, you'll need to add Toastr to your project. You can do this by including the Toastr CDN in your view files. Alternatively, you can download the Toastr files and include them in your project.

For this example, we'll use the CDN:

<script src="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/latest/toastr.min.js" integrity="sha512-VEd+nq25CkR676O+pLBnDW09R7VQX9Mdiij052gVCp5yVH3jGtH70Ho/UUv4mJDsEdTvqRCFZg0NKGiojGnUCw==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/latest/toastr.min.css" rel="stylesheet" />

Step 2: Create the Notification Partial View

Next, create a partial view _Notification.cshtml that will handle the Toastr notifications. This partial view will check if there are any messages in TempData and display them accordingly.

@if (TempData["error"] is not null)
{
    <script src="~/lib/jquery/dist/jquery.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/latest/toastr.min.js" integrity="sha512-VEd+nq25CkR676O+pLBnDW09R7VQX9Mdiij052gVCp5yVH3jGtH70Ho/UUv4mJDsEdTvqRCFZg0NKGiojGnUCw==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>

    <script type="text/javascript">
        toastr.error('@TempData["error"]');
    </script>
}


@if (TempData["success"] is not null)
{
    <script src="~/lib/jquery/dist/jquery.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/latest/toastr.min.js" integrity="sha512-VEd+nq25CkR676O+pLBnDW09R7VQX9Mdiij052gVCp5yVH3jGtH70Ho/UUv4mJDsEdTvqRCFZg0NKGiojGnUCw==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>

    <script type="text/javascript">
        toastr.success('@TempData["success"]');
    </script>
}

Step 3: Include the Partial View in Your Layout

To ensure that the notifications are displayed on every page where they might be needed, include the _Notification partial view in your main layout file (_Layout.cshtml).

<div class="container">
    <main role="main" class="pb-3">
        <partial name="_Notification" />
        @RenderBody()
    </main>
</div>

Step 4: Update Your Controller

Now, update your controller to set TempData values for success or error messages. Here's an example using a VillaController:

public class VillaController : Controller
{
    private readonly ApplicationDbContext _db;

    public VillaController(ApplicationDbContext db)
    {
        _db = db;
    }

    public IActionResult Create()
    {
        return View();
    }

    [HttpPost]
    public IActionResult Create(Villa obj)
    {
        if (ModelState.IsValid)
        {
            _db.Villas.Add(obj);
            _db.SaveChanges();
            TempData["success"] = "The villa has been created successfully";
            return RedirectToAction("Index");
        }

        TempData["error"] = "The villa could not be created";
        return View(obj);
    }

    public IActionResult Update(int villaId)
    {
        Villa? obj = _db.Villas.FirstOrDefault(m => m.Id == villaId);
        if (obj is null)
        {
            return RedirectToAction("Error", "Home");
        }
        return View(obj);
    }

    [HttpPost]
    public IActionResult Update(Villa obj)
    {
        if (ModelState.IsValid && obj.Id > 0)
        {
            _db.Villas.Update(obj);
            _db.SaveChanges();
            TempData["success"] = "The villa has been updated successfully";
            return RedirectToAction("Index");
        }

        TempData["error"] = "The villa could not be updated";
        return View(obj);
    }

    public IActionResult Delete(int villaId)
    {
        Villa? villa = _db.Villas.FirstOrDefault(v => v.Id == villaId);
        if (villa is null)
        {
            return RedirectToAction("Index");
        }
        return View(villa);
    }

    [HttpPost]
    public IActionResult Delete(Villa obj)
    {
        Villa? villa = _db.Villas.FirstOrDefault(m => m.Id == obj.Id);
        if (villa is not null)
        {
            _db.Villas.Remove(villa);
            _db.SaveChanges();
            TempData["success"] = "The Villa has been deleted successfully";
            return RedirectToAction("Index");
        }

        TempData["error"] = "Villa could not be deleted";
        return View(villa);
    }
}

Step 5: Test Your Toastr Notifications

Run your application and perform actions like creating, updating, or deleting a Villa. You should see the Toastr notifications appear as intended based on the result of the operation.

Understanding Data Annotations in .NET with a Practical Example

Azizul Arif — Fri, 30 Aug 2024 19:07:40 +0000

When building web applications with ASP.NET, data annotations are an essential tool for defining validation rules, display formatting, and model behaviors directly in your code. By using data annotations, you can simplify your code, improve maintainability, and ensure data integrity without writing extensive custom validation logic.

What Are Data Annotations?

Data annotations are attributes you can apply to model properties in .NET to enforce validation rules, control display formatting, and provide metadata about the data model. They help reduce repetitive code and streamline the validation process in your application.

Practical Example: Data Annotations in Action

Let's consider a basic example using a class named Villa. This class represents an entity in a hotel or rental application where users can manage different villas. One of the properties, Price, is decorated with a data annotation to specify how it should be displayed in the UI.

public class Villa
{
    public int Id { get; set; }
    public string Name { get; set; }

    [Display(Name="Price Per Night")]
    public double Price { get; set; }
}

Using the [Display] Attribute

In the example above, the Price property uses the [Display] attribute to specify how the property name should be presented in the UI. Instead of the default label "Price," it will be displayed as "Price Per Night," which provides clearer information to the user.

Why Use Data Annotations?

Readability: Data annotations make your code more readable and self-explanatory. By looking at the model, you can quickly understand the intended behavior and validation rules.

Maintainability: Centralizing your validation logic within your models makes it easier to maintain and update as your application evolves.

Consistent UI: Annotations like [Display] ensure that your UI consistently reflects the same labels and formats, reducing discrepancies across your application.

Example in a View

Here's how you might use this model in an ASP.NET Razor view:

<form method="post" class="row">
    <div class="form-floating py-2 col-md-12">
        <input asp-for="Name" class="form-control shadow border" />
        <label asp-for="Name" class="ms-2 text-black"></label>
    </div>
    <div class="form-floating py-2 col-md-12">
        <input type="number" asp-for="Price" class="form-control shadow border" />
        <label asp-for="Price" class="ms-2 text-black"></label>
    </div>

</form>

In this form, the Price field will display "Price Per Night" as its label, thanks to the [Display] attribute applied to the model property.

Conclusion
Data annotations are a powerful feature in .NET that allow developers to enforce validation rules, control display formatting, and provide metadata directly within their models. By leveraging these attributes, you can write cleaner, more maintainable, and user-friendly applications.

How to Seed Data in .NET Core Using Entity Framework

Azizul Arif — Thu, 29 Aug 2024 15:55:20 +0000

When building applications with .NET Core, it's often necessary to pre-populate the database with some initial data. This process is known as database seeding. In this article, we'll walk through the steps to seed a database with initial data using Entity Framework Core, using a practical example from a project.

What is Database Seeding?

Database seeding is the process of populating a database with an initial set of data when it is created. This can be particularly useful for testing, as it allows you to have some baseline data available in your development environment.

Setting Up the Model

Let's start with a simple model that represents a Villa. This model is part of our domain and will be used to define the structure of the data we want to seed.

using System;

namespace BulkyWeb.Domain.Entity
{
    public class Villa
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string? Description { get; set; }
        public double Price { get; set; }
        public int Sqft { get; set; }
        public int Occupacy { get; set; }
        public string? ImageUrl { get; set; }
        public DateTime CreatedDate { get; set; }
        public DateTime UpdatedDate { get; set; }
    }
}

In this example, the Villa class has several properties like Id, Name, Description, Price, and more, which define the structure of a villa in our system.

Configuring the DbContext

Next, we'll configure our ApplicationDbContext to include seeding logic. The OnModelCreating method is the place where we can define our seed data.

using Microsoft.EntityFrameworkCore;

public class ApplicationDbContext : DbContext
{
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // base.OnModelCreating(modelBuilder);
        modelBuilder.Entity<Villa>().HasData(
            new Villa
            {
                Id = 1,
                Name = "Royal Villa",
                Description = "Fusce tincidunt maximus leo, sed scelerisque massa auctor sit amet.",
                ImageUrl = "https://placehold.co/600x400",
                Occupacy = 4,
                Price = 200,
                Sqft = 550,
                CreatedDate = DateTime.Now,
                UpdatedDate = DateTime.Now
            },
            new Villa
            {
                Id = 2,
                Name = "Premium Pool Villa",
                Description = "Donec ex mauris, hendrerit quis nibh ac, efficitur fringilla enim.",
                ImageUrl = "https://placehold.co/600x401",
                Occupacy = 4,
                Price = 300,
                Sqft = 550,
                CreatedDate = DateTime.Now,
                UpdatedDate = DateTime.Now
            },
            new Villa
            {
                Id = 3,
                Name = "Luxury Pool Villa",
                Description = "Auctor sit amet. Fusce tincidunt maximus leo.",
                ImageUrl = "https://placehold.co/600x402",
                Occupacy = 4,
                Price = 400,
                Sqft = 750,
                CreatedDate = DateTime.Now,
                UpdatedDate = DateTime.Now
            }
        );
    }
}

In this code, we use the HasData method to seed three different villas into the database. Each villa is defined with its properties, such as Id, Name, Description, Price, etc. The CreatedDate and UpdatedDate fields are set to the current date and time.

Applying the Migration

After setting up the seed data, the next step is to create a migration and apply it to the database.

Step 1: Create the Migration
Run the following command in the Package Manager Console (PMC) or Terminal to create a migration:

add-Migration SeedVillaTable

Step 2: Update the Database

update-Database

This command applies all pending migrations, including the one we just created, to the database. It will also execute the seed data we defined, populating the Villa table with the initial data.

Verifying the Seed Data

After running the migration and updating the database, you can verify that the seed data was successfully added by querying the Villa table in your database. You should see the three villas we defined in the seed data.

Understanding Routing in .NET: A Guide for Developers

Azizul Arif — Tue, 27 Aug 2024 16:27:07 +0000

What is Routing?

Routing in .NET is the mechanism that directs an HTTP request to the appropriate controller action or endpoint. It plays a critical role in determining how URLs are interpreted by the application and how requests are handled. When a request comes in, the routing engine examines the URL and matches it against a defined set of routes. If a match is found, the corresponding action or endpoint is invoked to process the request.

Setting Up Routing in ASP.NET Core
In ASP.NET Core, routing is configured in the Startup.cs file within the Configure method. Here's a basic example:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
        app.UseHsts();
    }

    app.UseHttpsRedirection();
    app.UseStaticFiles();

    app.UseRouting();

    app.UseAuthorization();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllerRoute(
            name: "default",
            pattern: "{controller=Home}/{action=Index}/{id?}");
    });
}

In this example, the UseRouting middleware is added to the pipeline to enable routing. The UseEndpoints method is used to define the route pattern. The pattern parameter specifies the route template, where {controller}, {action}, and {id?} are placeholders that correspond to the controller name, action method, and optional ID parameter.

Attribute Routing

In addition to conventional routing, ASP.NET Core supports attribute routing. Attribute routing allows you to define routes directly on controller actions, providing more control and flexibility.

[Route("products")]
public class ProductsController : Controller
{
    [HttpGet("{id}")]
    public IActionResult Details(int id)
    {
        // Action logic here
        return View();
    }

    [HttpPost("create")]
    public IActionResult Create(Product product)
    {
        // Action logic here
        return RedirectToAction("Index");
    }
}

In this example, the Details action method is accessible via products/{id}, and the Create action method is accessible via products/create. This approach is particularly useful when you want to have more descriptive and SEO-friendly URLs.

Advanced Routing Techniques

Route Constraints
Route constraints are used to restrict the routes based on certain conditions. For instance, you can enforce that a route parameter must be an integer:

endpoints.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id:int?}");

Here, the id parameter must be an integer, and the route will only match if the condition is satisfied.

Custom Route Handlers
In some cases, you might need more control over how routes are handled. You can create custom route handlers by implementing the IRouter interface. This allows you to define your routing logic and handle requests in a unique way.

public class CustomRouteHandler : IRouter
{
    public Task RouteAsync(RouteContext context)
    {
        var requestPath = context.HttpContext.Request.Path.Value;

        if (requestPath.Contains("custom-route"))
        {
            // Custom logic here
            context.Handler = async ctx =>
            {
                await ctx.Response.WriteAsync("This is a custom route handler!");
            };
        }

        return Task.CompletedTask;
    }

    public VirtualPathData GetVirtualPath(VirtualPathContext context)
    {
        return null;
    }
}

This custom route handler checks if the request path contains "custom-route" and handles it accordingly.

Routing in .NET is a versatile and powerful feature that allows you to design clean and efficient URL structures for your web applications. Whether you’re using conventional routing, attribute routing, or advanced techniques like route constraints and custom route handlers, understanding how routing works will enable you to build more scalable and maintainable applications.

Exploring Cloud Deployment Models in Azure: Public, Private, and Hybrid

Shared Responsibility Model in Azure: A Comprehensive Guide

Azizul Arif — Tue, 02 Jul 2024 05:47:18 +0000

The shared responsibility model is a fundamental concept in cloud computing, outlining the division of security and compliance responsibilities between a cloud service provider (CSP) and its customers. Understanding this model is crucial for effectively managing and securing your cloud resources. In this article, we will explore the shared responsibility model in Azure, providing insights into what responsibilities lie with Microsoft and what responsibilities lie with you, the customer.

What is the Shared Responsibility Model?
The shared responsibility model delineates the division of security responsibilities between Microsoft Azure and its customers. This model ensures that both parties understand their roles in securing the cloud environment, thereby reducing the risk of security breaches and compliance issues.

Physical Datacenter Security: Ensuring the physical security of data centers, including access controls, surveillance, and maintenance.
Network Controls: Implementing network-level protections, including DDoS protection, and ensuring secure data transfer within Azure data centers.

Host Infrastructure Security: Managing the security of the hardware, firmware, and foundational software, such as the hypervisor, that run the cloud services.

Application and API Security: Ensuring the security of applications and APIs provided as part of Azure services.

Responsibilities of Azure Customers
Customers using Azure services are responsible for managing and securing their own data, applications, and configurations. Key responsibilities include:

Data Security: Protecting data stored in Azure, including implementing encryption, access controls, and backups.
Identity and Access Management (IAM): Managing user identities, enforcing strong authentication, and ensuring least-privilege access to resources.

Application Security: Securing applications that are deployed on Azure, including regular updates, patches, and vulnerability assessments.

Configuration Management: Ensuring the proper configuration of Azure services, including network security groups, virtual networks, and firewalls.

Compliance: Ensuring that applications and data comply with relevant regulatory requirements and industry standards.

Examples of the Shared Responsibility Model
To better understand how this model works in practice, let's look at a couple of common scenarios:

Infrastructure as a Service (IaaS):

Microsoft's Responsibilities: Physical host and network infrastructure security, including virtualization.

Customer's Responsibilities: Operating system, application, and data security, including patching and updates.

Platform as a Service (PaaS):

Microsoft's Responsibilities: Underlying infrastructure, runtime environment, and managed services security.

Customer's Responsibilities: Application and data security, including configuration and access management.
Software as a Service (SaaS):

Microsoft's Responsibilities: Entire stack including the application.

Customer's Responsibilities: Data security and access management.
Best Practices for Customers

To effectively manage your responsibilities in Azure, consider the following best practices:
