On click event of grid view

Hi @Aftab5124

If you don't want to use the grid view row command then you can use commandname property for each control.and under that command name perform what you want to do.
for ex

<asp:GridView ID="GridView1" runat="server" BackColor="White"
           BorderColor="White" BorderStyle="Ridge" BorderWidth="2px" CellPadding="3"
           CellSpacing="1" GridLines="None">
           <RowStyle BackColor="#DEDFDE" ForeColor="Black" />
           <Columns>
              <asp:TemplateField>
              <ItemTemplate>
              <asp:Button runat="server" Text="clickme" CommandName="showdata()" />
              </ItemTemplate>
              </asp:TemplateField>
               <asp:TemplateField>
              <ItemTemplate>
              <asp:LinkButton ID="Button2" runat="server" Text="clickme" CommandName="showdata()"></asp:LinkButton>
              </ItemTemplate>
              </asp:TemplateField>
           </Columns>
           <FooterStyle BackColor="#C6C3C6" ForeColor="Black" />
           <PagerStyle BackColor="#C6C3C6" ForeColor="Black" HorizontalAlign="Right" />
           <SelectedRowStyle BackColor="#9471DE" Font-Bold="True" ForeColor="White" />
           <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#E7E7FF" />
       </asp:GridView>

Here i have called the showdata command name for the button1 as well as the button2

Hope it will help you

Thanks
