repeater怎么获取内部的html控件
前台
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<input id="Text1" name="Text1" type="text" value='<%#Eval("txt") %>' />
<br />
</ItemTemplate>
<AlternatingItemTemplate>
<input id="Text1" name="Text1" type="text" value='<%#Eval("txt") %>' />
<br />
</AlternatingItemTemplate>
</asp:Repeater>

后台怎么获取text1的值？
string str = ((HtmlInputText)(Repeater1.Items[0].FindControl("Text1"))).Value;报错

------解决方案--------------------------------------------------------
点按钮post后，request.form["Text1"]
你这个都没有runat=“server”，后台肯定拿不到
------解决方案--------------------------------------------------------
name设成唯一的，并且可预测的，我就经常用前缀+value的格式

<input id="Text1<%#Eval("txt") %>" name="Text1" type="text" value='<%#Eval("txt") %>' />

后台用request.form[“”]

C# code

  protected void rpt_Role_ItemCommand(object source, RepeaterCommandEventArgs e)        {            ImageButton show = (ImageButton)e.Item.FindControl("imgBtnShow");            ImageButton hidden = (ImageButton)e.Item.FindControl("imgBtnHidden");            Panel pl_shDetail = (Panel)e.Item.FindControl("pl_ShowHiddenDetail");            if (e.CommandName == "ShowDetail")            {                show.Visible = false;                hidden.Visible = true;                pl_shDetail.Visible = true;                unFold(e);            }            if (e.CommandName == "HiddenDetail")            {                show.Visible = true;                hidden.Visible = false;                pl_shDetail.Visible = false;            }            if (e.CommandName == "edit")            {                GV_Detail.EditIndex = -1;                string MemberID = e.CommandArgument.ToString();                loadDetail(MemberID);            }        }

你用表单传值吧
