Setting minimum and maximum values for DxMaskedInput in Blazor

Hello👋 fellow Blazor developers, I am seeking help with setting minimum and maximum values for DxMaskedInput tag in Blazor. I am currently using the following code:

<DxMaskedInput @bind-Value="@_dealSize"
Enter fullscreen mode Exit fullscreen mode

I want to set the minimum and maximum values for _dealSize, but I am encountering an error when trying to use the following code example that uses the ValueChanged event:

<DxMaskedInput Value="Value"
            ValueChanged="@((int newValue) => OnValueChanged(newValue))"
<DxButton Enabled="@IsEnabled">Update Value</DxButton>

@code {
    int Value = 0;
    bool IsEnabled = false;

    void OnValueChanged(int newValue)
        Value = newValue;
        if (newValue != 0)
            IsEnabled = true;
        else IsEnabled = false;
Enter fullscreen mode Exit fullscreen mode

The error I am encountering is:

"Message":"Unhandled exception in circuit \u0027WRZkSd3ggsKGlKKJZfwrV9sDpWQEmJjBFDRYdMjbsoc\u0027.",
DevExpress.Blazor.Internal.Editors.Models.MaskedInputModel requires a value for the \u0027ValueExpression\u0027 property. 
It is specified automatically when you use two-way binding(\u0027bind-Value\u0027).    at

"{OriginalFormat}":"Unhandled exception in circuit \u0027{CircuitId}\u0027."}}
Enter fullscreen mode Exit fullscreen mode

If anyone has experience with this, I would greatly appreciate any help or suggestions. Thank you in advance!🙏
