Hello,

The code as described above is slightly confusing. You have two event handlers. The first increases the variable v_total with 1, while the second fills a dataset with an SQL query from a database. Then, you bind that dataset as a datasource to the gridview. The bit that I'm missing is where you want to use the v_total in your gridview. You can only bind one datasource to your gridview so you'll have to bind your value directly to a column or cell. If you want to , for example, bind that value to a particular label in your gridview, you could try something like this :

XML

<asp:GridView ID="gridProgress" runat="server" AutoGenerateColumns="False">
    <Columns>
       <asp:TemplateField HeaderText="Total Value">
          <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" Width="10%" />
          <HeaderStyle HorizontalAlign="Center" />
          <ItemTemplate>
              <asp:Label ID="lblTotalValue" runat="server"></asp:Label>
          </ItemTemplate>
      </asp:TemplateField>
    </Columns>
</asp:GridView>

Use the FindControl property of Gridview :

Label lbl = GridView3.Rows[rowIndex].FindControl("lblTotalValue") as Label;
lbl.Text = Convert.ToString(v_total);

Of course, you could bind your value to other controls inside your gridview as well. You could also add your value v_total to the dataset ( or datatable (works cool as datasource as well)) and then bind it directly to the gridview. Hope this helps.
