Remarks

The example below demonstrates how to handle the ReadOnlyChanged event. The handler responds to read-only mode activation:

<DxRichEdit Id="myRich" @ref="richEdit" ReadOnly="@readOnly" 
    ReadChanged="@((value) => OnReadOnlyChanged(value))" />
@code {
    DxRichEdit richEdit { get; set; }
    bool readOnly { get; set; }

    async Task OnReadOnlyChanged(bool value) {
    /* Surround the code that contains an asynchronous operation with a try-catch block to handle
    the OperationCanceledException. This exception is thrown when an asynchronous operation is cancelled. */
        try {
            readOnly = value;
            if (readOnly) {
                // Your code
            }
        }
        catch (OperationCanceledException e) {
            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
        }
    }
}
