@code {
DxRichEdit richEdit;
Document documentAPI;
@* ... *@
/* 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 {
documentAPI = richEdit.DocumentAPI;
@* ... *@
// Creates and updates a DATE field
Field newField = await documentAPI.Fields.CreateAsync(10, "DATE");
await documentAPI.Fields.UpdateAsync(newField);
// Gets the field result of the updated field
newField = await documentAPI.Fields.GetAsync(newField.Index);
TextSpan fieldResult = await documentAPI.GetTextSpanAsync(newField.ResultInterval);
// Deletes the field
await documentAPI.RemoveAsync(newField.Interval);
// Inserts the field result
await documentAPI.AddTextAsync(newField.Interval.Start, fieldResult.Text);
@* ... *@
}
catch (OperationCanceledException e) {
Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
}
