private void AddOrderID(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
//如果当前项不为空
if(e.Item.ItemIndex != -1 )
{
//取得当前项的索引值加1,因为项的索引值是从0开始的.
int orderID = e.Item.ItemIndex+1;
//设置第一列为的单元格内容为当前项索引值加1
e.Item.Cells[0].Text = orderID.ToString();
}
}

-------- 在datagrid 前添加序号 ---------
<asp:TemplateColumn>
<ItemTemplate>
<%#(DataGrid1.CurrentPageIndex*DataGrid1.PageSize+DataGrid1.Items.Count+1)%>
</ItemTemplate>
</asp:TemplateColumn>

1.加一个绑定列
2.在DataGrid控件的ItemDataBound事件中处理
//如果当前项不为空
if(e.Item.ItemIndex != -1 )
{
//取得当前项的索引值加1,因为项的索引值是从0开始的.
int orderID = e.Item.ItemIndex+1;
//设置第一列为的单元格内容为当前项索引值加1
e.Item.Cells[0].Text = orderID.ToString();
}

首先在DataGrid中加入一个序号的模板列，然后在DataGrid的ItemDataBound事件中如此操作：

if (e.Item.ItemIndex >= 0)
{
intRecordCount = this.QDataGridProjectQuery.PageSize * this.QDataGridProjectQuery.CurrentPageIndex + e.Item.ItemIndex + 1;
//e.Item.Cells[i].Text = intRecordCount.ToString();
((Label)e.Item.Cells[i].FindContrl["Label1"]).Text = intRecordCount.ToString();
}
