GridView显示总合计

 <asp:GridView ID="GridView1" runat="server" Width="100%" DataKeyNames="ID" AutoGenerateColumns="False"  OnRowDataBound="GridViewIw1_RowDataBound" >
    <Columns>
。。。。。。。。。。。。。。。
 <asp:BoundField DataField="SumPrice" HeaderText="金额"  SortExpression="SumPrice" DataFormatString="{0:C}" HtmlEncode="False"  >
                              <itemstyle width="8%" />

                              </asp:BoundField>
。。。。。。。。。。。。。。。。。
</Columns>
</asp:GridView >

格式化的时候一定要把HtmlEncode设为"False"

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        
        DataControlRowType lit = e.Row.RowType;
        if (lit == DataControlRowType.Footer)
        {           
            TableCell tcprice = e.Row.Cells[3];            
            TableCell price = e.Row.Cells[4];
                        tcprice.Text = "总金额:";
                       tcprice.HorizontalAlign = HorizontalAlign.Right;
                    price.Text = "￥"+GetPrice();
                           
        }
           }

private string  GetPrice()
{
return "3459";
}

在脚里就能显示总合计了！
