1.編輯時綁定下拉列表的選定

要點:
a.要命名隱藏列變為只讀狀態(屬性生成器|列|選定列勾選只讀),否則e.Item.Cells[count-2].Text總為空.

private void Datagridex2_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
		{			
			if(e.Item.ItemType == ListItemType.EditItem)//編輯狀態
			{
				int count = this.Datagridex2.Columns.Count;
				if(e.Item.Cells[count-2].Text=="0")
				{
					((DropDownList)e.Item.Cells[count-7].FindControl("DDLevel")).SelectedIndex=0;
				}
				else
				{
					((DropDownList)e.Item.Cells[count-7].FindControl("DDLevel")).SelectedIndex=1;
				}
			}
		}
