第 1 步:在某处绑定数据
第二步:处理 OnItemDataBound 事件,在这里找到你的控件,类似下面...
protected void DataList1__ItemDataBound(Object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.EditItem)
{
Label lbl = (Label)e.Item.FindControl("lbl");
lbl.Text = "edit mode";
}
}
有关此事件的更多信息,请查看MSDN 示例。您必须检查 ItemType。在这种情况下,它处于编辑模式,否则您检查列表项或替代项等。
