Hello Kashir,

I have examined the code and it seems correct. With that said, note that using AjaxControlToolkit can break some of the features in our controls. Would you remove the ModalPopupExtender and any reference to the Toolkit? Also, ensure that you are using the standard ScriptManager or RadScriptManager on the page and see if it makes a difference.

For additional information on the matter please examine the following thread:
