Type | Description |
---|---|
Cancellation |
An object that notifies that the Update operation should be canceled. |
#Remarks
Use the GridRowValidationEventArgs.UpdateRowResult property to specify a task that asynchronously posts changes to an underlying data source (database).
You can allow users to cancel the Update operation, for example, when they click the Cancel button. To do that, set the GridRowValidationEventArgs.UseCancellationToken property to true and use the GridRowValidationEventArgs.CancellationToken
in a cancel function.
C#
private void On_ValidateRow(object sender, GridRowValidationEventArgs e) {
// ...
e.UseCancellationToken = true;
e.Register(() => DoSomethingToCancelOperation())
e.ResultAsync = Task.Run(() => {
// ...
e.CancellationToken.ThrowIfCancellationRequested();
// ...
});
// ...
}
