Controls inside the Rad ajax panel gives error

[Ragupathi]

Hi,
I have created a custom control with two comboboxes and labels. i am using the selected changed event there. So if use any postback event it gives a javascript error:
SysArgument Undefinedexception: value cannot be undefined.parameter name:Type.


The same control without using Radajaxpanel is working fine. please give me a solution to work with my custom control inside the rad ajaxpanel (without post back)

Thx

Does the error pop up when you remove the RadAjaxPanel and use plain MS UpdatePanel? If the issue comes up only with RadAjaxPanel, post a sample project through the support ticketing system and the folks from Telerik will assist you.
