DataGrid脚眉显示合计

  

创建一个全局变量   





Public double Sumdb; 







 



private void DataGrid1_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 





         {             





              ListItemType lit=e.Item.ItemType; 





              if(lit==ListItemType.Footer) 





              { 





              





                   TableCell tc1=e.Item.Cells[3]; 





                   TableCell tc2=e.Item.Cells[4]; 





                   TableCell tc3=e.Item.Cells[5]; 





                   TableCell tc4=e.Item.Cells[6]; 





              





                   Label L_xj=new Label(); 





                   L_xj.ID="lb_xj"; 





                   L_xj.Width=30; 





                   L_xj.Text="合计"; 





                   tc1.Controls.Add(L_xj);
