Hi,

I am using TabContainer asp.net control. Inside tabcontainer i am using more than 1 tabpanel. Each panel i have gridview. When tabpanel is clicking I am binding values to gridview control. So in Tabcontainer i have added PostBack="true" properties and OnActiveTabChanged event also i have writen. My problem is everything is working fine but page is going up when tabpanel is clicking. If make it PostBack="false" page is not going up. But i should call server side code when i am clicking tab panel. So please suggest me what could be the problem?
