隐藏DateList中的label控件.

[zz_feng]

我 在datalist中放入一个table,其中table里面放入了几个label控件，在读出数据后

我想对其中的一个控件label隐藏，应该怎么操作？

希望各位高手指点，谢谢！

用item的FindControl("labelid")

[jiang_jiajia10]

foreach (RepeaterItem item in this.rptSerchHot.Items)
        {
                Label lbl1 = (Label)item.FindControl("lbl1");
                Label lbl2 = (Label)item.FindControl("lbl2");
                Label lbl3 = (Label)item.FindControl("lbl3");

            }
        }
找到了就可以做判断了。如if(条件){lbl1.visible=true;}

你是要在后台还是JS中操作?

findcontrol然后设置visible=false

C# code
foreach (RepeaterItem item in this.rptSerchHot.Items)
{
Label lbl1 = (Label)item.FindControl("lbl1");
Label lbl2 = (Label)item.FindControl("lbl2");
Label lbl3 = (Label)item.FindControl("lbl3");

}
}

<asp:DataList ID="dListProduct" OnItemDataBound="dListProduct_ItemDataBound" runat="server" Style="font-size: 13px"> 

protected void dListProduct_ItemDataBound(object sender, DataListItemEventArgs e) 
{ 
   if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) 
   {
      Label lblName1=e.Item.FindControl("lblName1") as Label;
      Label lblName2=e.Item.FindControl("lblName2") as Label;
      Label lblName=e.Item.FindControl("lblName") as Label;
      
      lblName2.Visible=false;
      lblName1.Visible=false;

   }
}
