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);

Label L_SumData= new Label();

L_SumData.ID="L_SumData";

L_SumData.Width=30;

L_SumData.Text=SumData();

tc2.Controls.Add(L_SumData);

Label L_zj= new Label();

L_zj.ID="lb_zj";

L_zj.Width=30;

L_zj.Text=" 总合计 ";

tc1.Controls.Add(L_zj);

Label L_SumPage = new Label();

L_SumPage.ID= ” l_sumPage ” ;

L_SumPage.Width=30;

L_SumPage.Text = Sumdb.ToString();

tc4.Controls.Add(L_SumPage);

}

}

private void DataGrid1_ItemDataBound( object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)

{

if (e.Item.ItemType==ListItemType.AlternatingItem || e.Item.ItemType==ListItemType.Item)

{

if ( Convert.ToString( ((DataRowView)e.Item.DataItem)["M_sum"]) != string .Empty)

{

dataSum += Convert.ToDouble(((DataRowView)e.Item.DataItem)["M_sum"]);

}

}

}

//M_sum 为合计的字段名，绑定在 DataGrid 的！
