Error on Adding Telerik Controls.

[Velkumar]

   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.

Hi Velkumar,

Can you provide some code that we could test locally and observe the exception that you describe? Can you also clarify the version of the Telerik controls that you are using?

Kind regards,

Hi

     We are using telerik 2010. I would like to say one thing that is if i am adding rad calendar, RadBinaryImage no error will occur. But if am adding radgrid, radcombo, radbutton then the error will occur.

Thanks,
Velkumar.

Hello Velkumar,

In order to help you out I would need to be able to reproduce the issue on the first place. Therefore I would suggest that open a support ticket where you can attach a runnable project that we can test locally.  It will also be very useful if you can send me the steps to reproduce the issue. 

All the best,
