[帮助]获得转发器中radiobutton的价值 [英] [Help] Get value of radiobutton in repeater

问题描述

我正在通过asp.net进行app测验

我在ASPX页面上有一个Repeater控件定义如下：

I'm making app quiz by asp.net
I have a Repeater control on ASPX-page defined like this:

<asp:Repeater runat="server" ID="rpQuestion" OnItemCommand="rpQuestion_ItemCommand"  >
  <ItemTemplate>
<li id="1" class="items">
 <span class="question"><%#Eval("QuestionName") %></span>
  <div class="btn-group">
<asp:RadioButtonList ID="rpList" runat="server"  RepeatDirection="Horizontal" OnSelectedIndexChanged="rpList_OnSelectedIndexChanged" >
<asp:ListItem Value="1" Text="1" >True</asp:ListItem>
<asp:ListItem Value="2" Text="2"> False</asp:ListItem>
 </asp:RadioButtonList>
 </div>
</li>
 </ItemTemplate>
 </asp:Repeater>

我无法获得每个radiobuttonlist的值
如果可以获得
，则值为null

帮助我调试这个或者请给我一个关于在转发器中使用radiobutton测验的简单应用程序？谢谢你

if can get , value is null
Help me debug this or please give me a simple app about quiz using radiobutton in repeater? thank you

Check this Code :--

<asp:Repeater runat="server" ID="rpQuestion">
         <ItemTemplate>
             <li id="1" class="items">
                 <span class="question"><%#Eval("rpQuestion1") %> </br><%#Eval("rpQuestion2") %></span>
                 <div class="btn-group">
                     <asp:RadioButtonList ID="rpList" runat="server" RepeatDirection="Horizontal">
                         <asp:ListItem Value="True" Text="1">True</asp:ListItem>
                         <asp:ListItem Value="False" Text="2"> False</asp:ListItem>
                     </asp:RadioButtonList>
                 </div>
             </li>
         </ItemTemplate>
     </asp:Repeater>

     <asp:Label ID="RadioButtonValue" runat="server"></asp:Label>
     <asp:Button ID="save" runat="server" Text="save" OnClick="save_Click" />

Server side Code :-

protected void Page_Load(object sender, EventArgs e)
       {
           if (!IsPostBack)
           {
               DataTable dt = new DataTable();
               dt.Columns.Add("rpQuestion1");
               dt.Columns.Add("rpQuestion2");

               DataRow dr;
               dr = dt.NewRow();
               dr["rpQuestion1"] = "test1";
               dr["rpQuestion2"] = "test2";

               dt.Rows.Add(dr);
               rpQuestion.DataSource = dt;
               rpQuestion.DataBind();
           }
       }

protected void save_Click(object sender, EventArgs e)
       {

           string rdValues = "";
           for (int i = 0; i < this.rpQuestion.Items.Count; i++)
           {
               RadioButtonList rpList = (RadioButtonList)this.rpQuestion.Items[i].FindControl("rpList");
               //this always returns 0
               string value = rpList.SelectedValue;
               RadioButtonValue.Text += value;
           }
       }
