The following code snippet handles the ReadOnlyChanged
event. The handler responds to read-only mode activation:
<DxRichEdit @ref="richEdit" ReadOnly="@readOnly"
ReadOnlyChanged="@((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 canceled. */
try {
readOnly = value;
if (readOnly) {
// Your code
}
}
catch (OperationCanceledException e) {
Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
}
}
}
