How to prevent postback on gridview

Question

I have a gridview which causes postback when I want to edit a row by clicking on the "edit" in my gridview.

How can I prevent postback upon editing?

Answer 1

use Ajax Update Panel Control, Sample code.. this may helpful to you..


 <asp:UpdatePanel ID="grdUpdatePanel" runat="server" UpdateMode="Conditional">
   <ContentTemplate>
      <asp:GridView ID="grdItemDetails" runat="server">
         -- your code --
         -- your code --
         -- your code --
      </asp:gridView>
   </ContentTemplate>
 </asp:updatePanel>

Answer 2

I assume that In each row you have a edit button. On clicking the edit button you can populate the controls or your Data Entry Form without the postback. example RowBoundEvent of Gridview.

Add the onclick attributes on the edit button click in this event.
