轉發器中的單選按鈕？

Question

我已經設置了一個轉發器，可以為每個問題重復一個單選按鈕，每個問題中只需要一個單選按鈕，這是我的代碼，我怎樣才能使單選按鈕控件組？

<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound" OnItemCommand="Repeater1_ItemCommand">
    <ItemTemplate>
        <div class="text-left" >
            <strong>

                <div>
                    <strong>
                        <li>
                             <div id="outer" style="background-color: lightblue">  <%# Eval("QuetionText")%></div>
                           <br />

                        </li>
                        <div>

                        <asp:Repeater ID="Repeater2" runat="server">
                            <ItemTemplate>
                                <li>

                                <div >
                                     <asp:RadioButton ID="RadioButton1" runat="server"  Text ='<%# Eval("ExamQuestionAnswerText")%>'  ></asp:RadioButton>
                                    <%--<asp:CheckBox ID="CheckBox1" runat="server" Text= '<%# Eval("ExamQuestionAnswerText")%>' />--%>

                                </div>
                                    </li>
                            </ItemTemplate>
                            <FooterTemplate >

                            </FooterTemplate>
                        </asp:Repeater>
                            </div>
                    </strong>
                </div>


            </strong>
        </div>
    </ItemTemplate>

</asp:Repeater>

Answer 1

您可以通過綁定其屬性GroupName來在子中繼器中對單選按鈕進行分組，如下所示：

  <asp:RadioButton ID="RadioButton1" runat="server"  Text ='<%# Eval("ExamQuestionAnswerText")%>'  
GroupName='<%# Eval("QuestionId")%>'></asp:RadioButton>

您需要將QuestionId用作子轉發器的dataSource。
