请教panel在repeater中如何应用
将一个表格做成了一个asp:repeater,其中某一单元格里有几个控件,
我用aspanel将其括起来,id为panel1
希望利用其visible属性.
但是在页面中一加载就报错:
编译器错误信息: BC30451: 未声明名称“panel1”。
求高手解决啊 --------------------编程问答-------------------- 写代码时有加System.Web.UI.WebControls.= (System.Web.UI.WebControls.DataList)e.Item.FindContro()吗? --------------------编程问答-------------------- 不好意思,我是初学的.请问这一句应该放哪里啊.
放上我的源代码.

</script> --------------------编程问答-------------------- 我想用asp:panel将编辑/回复/删掉这三个控件框起来.隐藏
读到session后再显示.
但是出错,
没办法,加了一个button强制执行测试,还是不行.
一加载就出错,错误信息如一楼.
虚心请教原因 --------------------编程问答-------------------- 不光是不能在repeater中应用panel,将功能控件改用asp:imagebutton也不行, --------------------编程问答-------------------- 顶上去,在线等. --------------------编程问答-------------------- 有一点点想法了,
panel必须做数据绑定
<asp:Panel runat="server" ID="Panel<%# DataSet1.FieldValue("id",Container)%>"></asp:panel>
但是不知道程序怎么写 --------------------编程问答-------------------- 上述想法不对 --------------------编程问答-------------------- 还没有搞懂 --------------------编程问答-------------------- 不知道你要做什么。为什么要加个panel --------------------编程问答-------------------- 回楼上,我想用panel
将回复/编辑/删除这几个功能控件
用session判断一起隐藏显示 --------------------编程问答-------------------- 郁闷,关注一天了 --------------------编程问答-------------------- 自已顶起，原理似乎已经找到了,控制repeater中某个控件的属性
<asp:Repeater runat="server" id="rptLinkButton" onItemCommand="Button_Click">
<itemtemplate>
<li>
<asp:LinkButton runat="server" Text='<%# Container.DataItem("au_fname")%>' Visible="true"/>
</li>
</itemtemplate></asp:Repeater>
==========================
--------------------编程问答-------------------- 刚好最近看到一个类似的例子 拿去试试行不行
Sub rptLinkButton_Click(s As Object,e As RepeaterCommandEventArgs)
Dim lbtnSelected As LinkButton
lbtnSelected=e.Item.Controls(1)
lbtnSelected.visible=false
lblmsg.Text="you Selected " & lbtnSelected.Text
End Sub
<asp:Panel ID="manages" runat="server" Visible='<%# Session["nName"]!=null %>'>
<hr size="1" style="border:1px dotted #333;">
<a href="Reply.aspx?id=<%# Eval("id") %>">[回复]</a>
<a href="Default.aspx?action=del&id=<%# Eval("id") %>" onclick='return confirm("您确定删除吗?");'>[删除]</a>
<a href="Default.aspx?action=loginout" onclick='return confirm("您确定要退出管理模式吗?");'>[注销]</a>
<a href="RePass.aspx?id=<%# Eval("id") %>">[修改密码]</a>
</asp:Panel> --------------------编程问答-------------------- 我也刚开始也好奇, 提示找不到控件. 然后发现自动生成的代码被删除了..
最后思考了下.. asp:repeater 内不让放容器控件吧.
不相信你试试, 把Panel 拿到外面立刻就好了. --------------------编程问答-------------------- 楼上也是我, 登错帐号了.
(Repeater1.Items[0].FindControl("Panel1") as Panel1).
刚搜到,你试试. --------------------编程问答-------------------- --------------------编程问答-------------------- Panel p = top.FindControl("p") as Panel; --------------------编程问答-------------------- <asp:Repeater runat="server" ID="top">
<ul>
<asp:Panel runat="server" ID= "p">
</asp:Panel>
</ul>
</asp:Repeater>
------------
Panel p = top.FindControl("p") as Panel;
--------------------编程问答-------------------- 不知道楼主为何要这样做，repeater里面有个事件控制repeater的显示的，在判断Session的时候可以重新加载一下那个事件即可判断，无需使用repeater
补充：.NET技术 , ASP.NET
