指定datagrid编辑框的宽度及相映属性(转)备用

private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
  {
   if (e.Item.ItemType == ListItemType.EditItem)
   {
     TextBox txt = (TextBox)e.Item.Cells[2].Controls[0];
     txt.Width = 120;
        txt.Height =40;
        txt.TextMode = TextBoxMode.MultiLine;
        txt.BackColor = Color.Cyan;
   }

 }

个人注释:只有在DataGrid1_ItemDataBound事件里指定有效,在DataGrid1_UpdateCommand事件里无效

在DataGrid1_UpdateCommand事件里取值

string val = ((TextBox)e.Item.Cells[2].Controls[0]).Text;
