We did not implement our own error handling for RadAjax, as the MS AJAX framework already takes care of that. During
partial-page rendering, you can handle errors by doing the following:
-
Set the AllowCustomErrorsRedirect property, which determines how
the custom error section of the Web.config file is used when an error occurs during an asynchronous postback.
-
Handle the ScriptManager control's AsyncPostBackError event, which is raised when there is a page
error during an asynchronous postback.
-
Set the AsyncPostBackErrorMessage property, which is the error
message that is sent to the browser.
