Hi,
I have a panelbar in my page with four panel items. In each panelitem click an usercontrol (.ascx) will be loaded in that panelitem dynamically (asyn postback---ajax). After the pageload i clicked the second panel item. Now a javascript error occurs that is
Error: Sys.ArgumentUndefinedException: Value cannot be undefined.
Parameter name: type
This error occurs only if it contains telerik controls. I this controls contains asp.net controls then no error will occur
Please give a solution for this problem..
Thanks
Velkumar.
