怎么在后台取得repeater绑定的数据

Answer 1

只能在Repeater的ItemDataBound事件中，用FindControl方法获取，然后重新绑定，在其它地方用FindControl方法不行的。比如在事件中可以这样写 if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Button btn = (Button)e.Item.FindControl("btnDetail"); int i = Convert.ToInt32(btn.CommandArgument.ToString()); List<Model.NewsBodyInfo> listBody = new List<NewsBodyInfo>(); listBody = bllNews.historyMessagesByNewsID(i); Repeater rep = (Repeater)e.Item.FindControl("Repeaters"); rep.DataSource = listBody; rep.DataBind(); }
