I am trying to run this tooltip on hover of a grid cell.  The data for the tooltip is in a user control (ascx).  I am banging my head because I keep getting a client side error Sys.WebForms.PageRequestManagerParserErrorException

Hello Shannon,

This is caused by invalid server response and I advise that you step through the server code to see what changes the response, as instructed here: http://www.telerik.com/help/aspnet-ajax/tooltip-troubleshooting-common-issues.html#ServerErrorException.

Thanks for the quick reply.  I understand that it is an invalid server response. Google gave me that information.  Can you look through my code and see if you see anything that may change the server state?

Hi Shannon,

You should examine the actual response with a tool like Fiddler or the browser dev toolbar to see what is actually returned in order to get a bearing on what may be causing the problem.

At this point, what I can see is that you have many nested AJAX settings - an UpdatePanel around everything, including RadAjaxPanel and RadAjaxManager. You should avoid nesting settings like this.

Also, to AJAX-enable a RadWIndow, I advise that you examine this article, since a RadWindowManager or RadWIndow cannot be AJAX initiators: http://www.telerik.com/help/aspnet-ajax/window-ajaxifying.html.

As for the server code - any Response.Redirect() call in Page_Load can break the response, but there is no way for me to know whether one will be executed, only you can debug that as I cannot run this sample.

I cannot say anything about the custom classes you have and calls like CAOInformation.UpdateCheckInStatus(profileID);

Thus, I cannot be of much assistance with this, even though I had reviewed the code the first time I replied because noticing the Response.Redirect() calls is something Google would have already pointed out.
