推荐答案

使用FindControl()方法查找Label控件

Use FindControl() Method to find the Label control

protected void datalist_ItemDataBound(object sender, DataListItemEventArgs e)
{
    Label HeaderLabel=(Label) e.Item.FindControl("HeaderLabel");

        HeaderLabel.text="Your text";
}

DataList具有事件OnItemCreated，重写允许选择行类型:

DataList has event OnItemCreated, overriding allows select type of row:

Label _lblLabel1;
void Item_Created(Object sender, DataListItemEventArgs e)
{

   if (e.Item.ItemType == ListItemType.Footer)
   {

      __lblLabel1 =(Panel)e.Item.FindControl("lblLabel1");
     __lblLabel1.Text="";

    }

}
