OnrequestStart work the first time but not in the second

[H.]

Hi I have a webpart in sharepoint 2007 that load a web usercontrol. this Web Usercontrol has RadAjaxmanager with the client-event OnRequestStart. when the user clicks the RadTabSplit the first time the OnrequestStart is trigged but in the second time does not trigged again.  Actually the RadAjaxLodingPanel is not work neither. I test the same code outside Sharepoint in a web application solution and it is working correctly. What is the problem? should I do something diferent in sharepoint 2007? 

I am working wih this problem for three days and I have read many blog and forums but nobody has the answer. Please help me!!

Hello,

Could you please elaborate a bit more on your application? Does the RadAjaxManager placed on the MasterPage or in the WebPart. Pleas note that it is better practice to place the RadAjaxManager in the MasterPage of the project with the ScriptManager before it.

The web part is a smart web part that load a web user control. This web user control has the telerik controls included RadAjaxManager and ScriptManager. The masterpage does not have telerik controls.

Hi,

Could I kindly ask you to open a regular support ticket and send us runnable version of your webpart. Thus we will be able to deploy it locally and do our best to isolate the root cause of the issue you are facing.

All the best,
