   ............ 
   ...........
  &lt;asp:templatefield Visible="true" headertext="Title" &gt;
  &lt;edititemtemplate&gt;
          &lt;asp:checkbox id="chkTitle" runat="server" /&gt;
  &lt;/edititemtemplate&gt;
  &lt;/asp:templatefield&gt;
  
  &lt;asp:commandfield buttontype="Link" edittext="Edit" showeditbutton="true"/&gt;
   &lt;/columns&gt;
