Quick insert for table rows and columns

Restructured source code view

Key benefits:

• Improved readability: Clean indentation helps users understand the structure.
• Better editing experience: Easier to locate and modify specific tags or attributes.
• Reduces errors: Clear formatting helps prevent mistakes during manual code edits.

Word file import with drag and drop

Users can import .docx files directly into the text editor using a simple drag-and-drop interface. This enhancement simplifies the process of bringing external content into your application, making it especially useful for users who frequently work with structured documents.

You can now control the size of imported Word files to prevent performance issues. If a file exceeds the limit, the editor displays a clear message, keeping the experience smooth and predictable.

This feature enforces the maximum file size limit to ensure uploads remain within allowed boundaries.

<SfRichTextEditor>
    <RichTextEditorImportWord MaxFileSize="50000" /> 
</SfRichTextEditor>

Key benefits:

• Streamlined workflow: Quickly bring Word content into the editor.
• User-friendly interface: Drag-and-drop support simplifies the import process.
• Robust validation: Prevents performance issues with large files and provides clear error messages.

Save interval optimization with smarter change detection

In this release, the Blazor WYSIWYG Editor introduces a more intelligent way to detect content changes using a browser-native mechanism. Previously, the editor relied on fixed time intervals or manual triggers to initiate save operations, which could result in unnecessary processing or missed updates during rapid editing.

Now, the editor listens for real-time DOM changes such as text input, formatting updates, or element insertions and responds only when actual modifications occur. This leads to a more efficient and responsive autosave experience.

This enhancement is powered by the DOM MutationObserver API and works in conjunction with the AutoSaveOnIdle property.

@using Syncfusion.Blazor.RichTextEditor

<SfRichTextEditor 
    ID="AutoSave" 
    SaveInterval="saveInterval" 
    AutoSaveOnIdle="true" 
    Value="@Value">

    <p>Type or edit the content to be saved automatically in the editor</p>
    <RichTextEditorEvents ValueChange="UpdateStatus" />

</SfRichTextEditor>

@code {
    private string Value { get; set; } = "<p>Start to type a content to save</p>";
    private int saveInterval { get; set; } = 5000;

    private void UpdateStatus(Syncfusion.Blazor.RichTextEditor.ChangeEventArgs args)
    {
        // Place the codes here, which save the Rich Text Editor value into database.
        this.Value = args.Value;
    }
}

Key benefits:

• Improved performance: Reduces CPU usage during frequent edits.
• Reliable autosave: Ensures changes are captured accurately.
• Scalable: Ideal for large documents or high-frequency editing environments.

Detect and react to text selection changes

The Blazor HTML Editor now supports detecting changes in text selection, allowing developers to respond when users highlight or modify content. This capability enables more dynamic and interactive editing experiences, such as showing context-aware toolbars or triggering custom actions.

This functionality is triggered when the selection within the component changes.

With this capability, developers can implement contextual toolbars, inline formatting options, custom popups, or analytics tracking based on user selection. It’s a powerful tool for enhancing the editor’s responsiveness and tailoring the UI to user behavior.

@using Syncfusion.Blazor.RichTextEditor

<SfRichTextEditor>
    <RichTextEditorEvents SelectionChanged="@SelectionChanged" />
</SfRichTextEditor>

@code {
    private void SelectionChanged(SelectionChangedEventArgs args)
    {
        // Capture the selected text and selection details
    }
}

Key benefits:

• Real-time interactivity: React to user actions instantly.
• Custom UI behavior: Tailor the editor experience based on selection.
• Enhanced extensibility: Ideal for building advanced editing features.
