RadAjaxPanel Error - How to Resolve

[Brian Mains]

Hello,

I wrap some markup with a RadAjaxPanel.  I'm getting an error in a callback related to this, and I can't figure out why it's happening.  It's preventing the page from working, even though the debugger shows everything correctly setup.  So I was wondering: is there an event that fires when an error happens, so I know that it's an error that comes from the server, or is actually the error the debugger is telling me it is?  How can I potentially resolve where it may really be coming from?

Thanks.

Hello Brian,

Could you please specify what is the error you received? Also it will be helpful if you send us the problematic code for further investigation.

Hello,

The $removeHandler definition had a call for a._events, where it removes an event handler.  a._events is undefined, but _events is not.  The error was rather strange; it was related to a calendar extender control in the ACT.  Whenever the calendar appeared, I would get this error when the RadAjaxPanel posted back, for whatever reason.  As soon as I removed it and replaced it with a raddatepicker, it worked fine...

But the point is that I don't know how to catch and wrap the error, as is there a client-side success or failed handler for the RadAjaxPanel?

Thanks.

Hi Brian,

Our developers have already fixed the problem with RadAjax and calendar extender. You can download a latest internal built from your Telerik account where the fix would be available.

Kind regards,

I would like to know how to catch errors from the radajaxpanel as well.  I don't care what the error is - I don't want it swallowed by ajax; I want my code to get it and throw an error to be handled by my code.

Hi Nick,

You can refer to this article for possible approaches:
http://www.telerik.com/help/aspnet-ajax/ajax-error-handling.html

Here is a basic sample, where you can debug your project using the following event:

Copy Code

protected void RadScriptManager1_AsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e)
{
    Type errorType = e.Exception.GetType();
    string errorReason = e.Exception.Message;
}

Hope this helps.

All the best,
