hi all,

In my application I'm reading data from web service and to create tab control dynamically, and bind the grid view data also. When I run the first time it's running perfectly. After hit the data gridview paging index (ex. 2 or 3..) the error is came.

error:

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: An error has occurred because a control with id 'ctl04' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error.

can any one tell me how can solve this?

Thanks in advance.
