Grid View inside Update Panel recreates the grid view

I have a grid view inside an update panel with triggers

<asp:AsyncPostBackTrigger ControlID="gvemployee" EventName="RowUpdating" /><asp:AsyncPostBackTrigger ControlID="gvemployee" EventName="RowDeleting" /><asp:AsyncPostBackTrigger ControlID="gvemployee" EventName="RowCancelingEdit" /><asp:AsyncPostBackTrigger ControlID="gvemployee" EventName="RowDataBound" />

But When i Click on the edit link. the grid view gets recreated
