title: Ajax tab control's TabContainer_ActiveTabChanged event is fired on each postback
body: <p>I am using Ajax tab control, which includes grids in each tab. The grid have drop down list and button and I want to fire gridview's RowCommand event on button click of gridview Row. But the problem is whenever I click on the button, Tabcontainet_ActiveTabChanged event is fired and grid view is bind again before it fire the RowCommand event. </p>
  
  <p>I can not understand why this event is fired automatically even though I am not firing it intentionally. How can I fire RowCommand event in such cases??
  I tried both with update panel and without update panel.</p>
