DataGrid脚眉显示合计

发布日期：2021/4/1

创建一个全局变量

Public double Sumdb;

private void DataGrid_ItemCreated(object sender SystemWebUIWebControlsDataGridItemEventArgs e)

{

ListItemType lit=eItemItemType;

if(lit==ListItemTypeFooter)

{

TableCell tc=eItemCells[];

Label L_xj=new Label();

L_xjID=\lb_xj\;

L_xjWidth=;

L_xjText=\合计\;

tcControlsAdd(L_xj);

Label L_SumData=new Label();

L_SumDataID=\L_SumData\;

L_SumDataWidth=;

L_SumDataText=SumData();

tcControlsAdd(L_SumData);

Label L_zj=new Label();

L_zjID=\lb_zj\;

L_zjWidth=;

L_zjText=\总合计\;

tcControlsAdd(L_zj);

Label L_SumPage = new Label();

L_SumPageID=l_sumPage;

L_SumPageWidth=;

L_SumPageText = SumdbToString();

tcControlsAdd(L_SumPage);

}

private void DataGrid_ItemDataBound(object sender SystemWebUIWebControlsDataGridItemEventArgs e)

{

if(eItemItemType==ListItemTypeAlternatingItem || eItemItemType==ListItemTypeItem)

{

if( ConvertToString( ((DataRowView)eItemDataItem)[\M_sum\]) != stringEmpty)

{

dataSum += ConvertToDouble(((DataRowView)eItemDataItem)[\M_sum\]);

}

//M_sum为合计的字段名绑定在DataGrid 的！
