radiobuttonlist的更新面板

Question

我有两个单选按钮列表和复选框列表，当前在更新面板中设置为AutoPostback=true。 updatepanel的异步回发适用于复选框列表，但不适用于单选按钮列表。

这是我的代码：

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <div class="card-body">
            <asp:Panel runat="server" CssClass="pnl" GroupingText="Keuze grootte" Visible="false" ID="pnlSizes">
                <asp:RadioButtonList ID="rdblSize" AutoPostBack="true" CssClass="checklist" OnSelectedIndexChanged="rdblSize_SelectedIndexChanged" runat="server"></asp:RadioButtonList>
            </asp:Panel>
            <asp:Panel runat="server" CssClass="pnl" GroupingText="Keuze bijgerecht" Visible="false" ID="pnlExtraOption">
                <asp:RadioButtonList ID="rdblExtraOption" CssClass="checklist" runat="server"></asp:RadioButtonList>
            </asp:Panel>

            <asp:Panel runat="server" CssClass="pnl" GroupingText="Keuze garnering" Visible="false" ID="pnlGarnish">
                <asp:CheckBoxList ID="chkGarnish" AutoPostBack="true" CssClass="checklist" OnSelectedIndexChanged="chkGarnish_SelectedIndexChanged" runat="server" RepeatColumns="4"></asp:CheckBoxList>
            </asp:Panel>
            <asp:Panel runat="server" CssClass="pnl" GroupingText="Keuze saus" Visible="false" ID="pnlSauce">
                <asp:RadioButtonList ID="rdblSauce" CssClass="checklist" runat="server"></asp:RadioButtonList>
            </asp:Panel>

            <asp:Panel runat="server" CssClass="pnl" GroupingText="Keuze extra saus" Visible="false" ID="pnlExtraSauce">
                <asp:RadioButtonList ID="rdblExtraSauce" AutoPostBack="true" CssClass="checklist" runat="server"></asp:RadioButtonList>
            </asp:Panel>
            <asp:Panel runat="server" CssClass="pnl" GroupingText="Keuze drank" Visible="false" ID="pnlDrink">
                <asp:CheckBoxList ID="chklExtraDrink" AutoPostBack="true" CssClass="checklist" runat="server"></asp:CheckBoxList>
            </asp:Panel>
            <asp:Panel runat="server" CssClass="pnl" GroupingText="Keuze extra's" Visible="false" ID="pnlExtras">
                <asp:CheckBoxList ID="chkExtras" CssClass="checklist" runat="server"></asp:CheckBoxList>
            </asp:Panel>
            <div style="margin-top: 10px; margin-bottom: 5px; text-align: center">
                <asp:Button ID="btnSave" runat="server" ForeColor="White" Font-Bold="true" OnClick="btnSave_Click" BackColor="DarkRed" Font-Size="15px" Width="80%" Height="30px" Text="Button" />

            </div>
        </div>
    </ContentTemplate>
</asp:UpdatePanel>

这是UpdatePanel的限制，还是我在这里做错了什么？

似乎您没有为单选按钮列表设置“ AutoPostBack = true”。设置此属性并尝试，应该可以。

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
    <div class="card-body">
        <asp:Panel runat="server" CssClass="pnl" GroupingText="Keuze extra saus" Visible="true" ID="pnlExtraSauce">
            <asp:RadioButtonList ID="rd" AutoPostBack="true" CssClass="checklist" runat="server"></asp:RadioButtonList>
        </asp:Panel>

        <asp:Panel runat="server" CssClass="pnl" GroupingText="Keuze extra's" Visible="true" ID="pnlExtras">
            <asp:CheckBoxList ID="chk" CssClass="checklist" AutoPostBack="true" runat="server"></asp:CheckBoxList>
        </asp:Panel>
        <div style="margin-top: 10px; margin-bottom: 5px; text-align: center">
            <asp:Button ID="btnSave" runat="server" ForeColor="White" Font-Bold="true" OnClick="btnSave_Click" BackColor="DarkRed" Font-Size="15px" Width="80%" Height="30px" Text="Button" />

        </div>
    </div>
</ContentTemplate>
