        </Columns>
    </asp:GridView>

    <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" ValidationGroup="vld_Rows" />
    <asp:Button ID="btn_Save" runat="server" Text="Save" onclick="btn_Save_Click" ValidationGroup="vld_Rows1" />
    </ContentTemplate>

      <%--<Triggers>
    <asp:AsyncPostBackTrigger ControlID="Button1" EventName="Click" runat="server" />
    <asp:AsyncPostBackTrigger ControlID="CheckBox1" EventName="CheckedChanged" runat="server" />
</Triggers>--%>

    </asp:UpdatePanel>

Above is the Sample Code Which I have used. Upon Clicking Button(btn_Save) I need to validate the ValidateGroup with id as “vld_Rows1”

Please Suggest a Solution.

Thanks in Advance!

    Put the validation control in the same template where you put your control. In your scenario, your controls are in the footer template, so you should put the validation controls in footer template, and try to use validation group as well. e.g.

     <asp:TemplateField>
      <ItemTemplate>
      </ItemTemplate>
      <FooterTemplate>
          <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox><asp:RequiredFieldValidator
                        ID="RequiredFieldValidator1" runat="server" ValidationGroup="ft" ControlToValidate="TextBox3"
                        ErrorMessage="*"></asp:RequiredFieldValidator>
       </FooterTemplate>
 </asp:TemplateField>
