    The RadGrid offers a clientside event called OnDataBindingFailed which gets fired on the clientside (javascript) when there is a server side exception.

    What is the equivalent for the RadAjaxPanel and RadAjaxManager? I want to be able to handle all exceptions as gracefully as possible.

    Hello Bob,

    Generally you can handle endRequest event of PageRequestManager and see whether there is an error and handle it.
    02.function EndRequestHandler(sender, args)
    04.   if (args.get_error() != undefined)
    05.   {
    06.       var errorMessage;
    07.       if (args.get_response().get_statusCode() == '200')
    08.       {
    09.           errorMessage = args.get_error().message;
    10.       }
    11.       else
    12.       {
    13.           // Error occurred somewhere other than the server page.
    14.           errorMessage = 'An unspecified error occurred. ';
    15.       }
    16.       args.set_errorHandled(true);
    17.       //Show custom error dialog   
    18.   }

    Bellow you can find more details
