I have GridView with SqlDataSource to populate it. While I have Custom Search Control on my WebPage. When ever i click the srch btn to populate the grid its OK but when i put any srch data in any ctrl (e.g City = 'KHI' in city textbox) and then click the srch btn i suffered for the following msg
ERROR Message
====================================================================
An error has occurred because a control with id 'grdComplaints$ctl04$ctl00' 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.
====================================================================
If any one has been faced and resolved such error then plz help me.
Thanks for your time.

Search is my <asp:Button ID="btnSearch" runat="server" Text="Search" />
it is not in the Grid.
btnSearch_Click
does this
-------------------------------------------------------------------
If Me.grdComplaints.Rows.Count = 0 Then
lblErrorMsg.Text = "No Record Found."
Me.pnlListComplaints.Visible = False
Exit Try
End if
-------------------------------------------------------------------

Is there somewhere that you are changing the ID of the grid, or other controls you create dynamically?

During postback your control ids might be getting changed. Check the page source to see whether the control id is as you want to be.

Thanks Roopesh !
There was a mistake by me.GridView Control's EnableViewState Property was set to 'False' when i change it to 'True' it becomes functional.
Once again thanks for ur time.
