Hello Russell, When the ASPx Grid View throws a callback, it catches exceptions by default, because each exception during the page processing cancels page generation.Even if a callback occurs, the ASPx Grid View (and other DX controls) catch exceptions to show them in the appropriate format.For example, the ASPx Grid View shows an error message, the ASPx Callback Panel shows an alert and so on.
