如何在gridview的页脚中计算总价? [英] how to calculate total price in the footer of gridview?

问题描述

我在gridview的页脚中有此方法

I have this method in the footer of gridview

<asp:TemplateField HeaderText="SALARY">
                  <ItemTemplate>
                  <asp:Label ID="sal1" runat="server" Text='<%# Eval("Total") %>'></asp:Label>
                   </ItemTemplate>
<%--            <asp:BoundField DataField="Total" HeaderText="totalprice" />
--%>            <FooterTemplate>

           <%# gettotal()%>

         </FooterTemplate>
         </asp:TemplateField>

现在在此方法中，我想计算总计如何从gridview的total列中的所有单元格中获取值?

now inside this method I want to calculate the total how to get the values from all cells which in the total column in gridview ??

public int gettotal()
  {

      int totalsal = ;

      return totalsal;

  }

这里是示例总计的页脚............

Here is Example to total in footer............

protected void grdGuestTotal_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType.Equals(DataControlRowType.Footer))
        {
            //String NetSubTotal = string.Empty;
            // String SubTotal = string.Empty;
            Label NetSubTotal = ((Label)e.Row.FindControl("lblNetSubTotal"));
            Label FinalTotal = ((Label)e.Row.FindControl("lblTotal"));
            NetSubTotal.Text = Total.ToString();
            FinalTotal.Text = EndTotal.ToString();// (Convert.ToDouble(NetSubTotal.Text) + Convert.ToDouble(SubTotal.Text)).ToString();
        }
        if (e.Row.RowType.Equals(DataControlRowType.DataRow))
        {
            //String NetSubTotal = string.Empty;
            // String SubTotal = string.Empty;
            Label SubTotal = ((Label)e.Row.FindControl("lblSubTotal"));
            Label NetTotal = ((Label)e.Row.FindControl("lblNetTotal"));
            double value = Convert.ToDouble(SubTotal.Text);
            Total += value;
            double amount = Convert.ToDouble(NetTotal.Text);

            EndTotal += amount;
        }

    }
