推荐答案

附加 OnItemDataBound 事件与DataList控件类似这样

Attach OnItemDataBound event with your datalist like this

<asp:DataList ID="Dlitems" runat="server" RepeatDirection="Horizontal" RepeatColumns="4"
CellPadding="0" CellSpacing="15" OnItemCommand="Dlitems_ItemCommand" 
OnItemDataBound="Dlitems_ItemDataBound">
...

和定义它像这样

protected void Dlitems_ItemDataBound(Object sender, DataListItemEventArgs e)
{
   if (e.Item.ItemType == ListItemType.Header)
   {
       Label lblCat = (Label)e.Item.FindControl("lblcat");
       lblCat.Text = "Changed!";

    }    
}
