Issues on GridView Though ModalPopupExtender

Hi guys, good evening. I have this search interface that I work out through the use of a modalpopupextender and a panel. I used GridView in displaying all the customers. I enable the paging attribute of GridView control and I limit the total number of rows to be displayed. Now I have a three (3) page of the GridView control to browse. It is quite annoying that if a certain customer is located on the second page of the GridView control, the search interface window closes and so therefore I need to click again on the search button to display the search interface. Is there anyway in order for me to eliminate this issue? Please help me.

All you have to do is make sure you put the Update Panel within the Panel being used for you ModelPopupExtender Panel.
