you can create template column javascript prompt confirmation.

<itemtemplate>     <asp:linkbutton id="btndelete" runat="server" text="delete" commandname="delete"                      onclientclick="javascript:if(!confirm('are sure want delete record?')){return false;}">     </asp:linkbutton> </itemtemplate>
