hi,

I have RadTimePicker, and i need to forbid posting back when time is picked, so I have decided to use RadAjaxManager, now when I have use it and select time picker to update it self, I got this error in my other jquery/ javascript when I am getting ID of server controls client id:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

so what do I do to take out this error? or how do I prevent post back for time picker when time is selected?
