I have many controls visible simultaneously on my .NET 2.0 Windows Form. One of them is an "editor," and when the user tries to leave that control by clicking on another control, I want to prompt the user to save their editing session, with a "Yes/No/Cancel" prompt. If the user clicks "Yes" or "No", then (after saving if they clicked "Yes"), the original click event should be processed. if they click "Cancel," the user should remain in the original "editor" control.
To cancel, I just set the Validating event handler's CancelEventArgs argument's Cancel property to true (i.e., e.Cancel = true;).
However, displaying the MessageBox prompt in the Validating event interferes with the processing of the original event. How can I continue processing the original event when the user clicks "Yes" or "No"?
