asp.net - UpldatePanel 中的 ASP.Net RadioButtonList 仅选择第一项

Question

在我的 .aspx 页面中：我有 3 个 Radiobuttonlist，它们都连接到 Sqldatasource。

显示数据后，我单击的每个选项都会转到第一个选项并被选中。

例如，我选择了第三个选项，但它转到了第一个选项！

我没有向服务器写任何代码！！！我不知道为什么会这样。

我写的代码和下面的代码完全一样：

<form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
                <ProgressTemplate>
                    <p style="text-align:center;">
                        <img src="assets/ajax-loader.gif" /></p>
                </ProgressTemplate>
            </asp:UpdateProgress>
            <div class="col-md-6">
                <div class="col-md-12 alefbasystemdotcom">
                    <span style="font-weight: bold;">Zusatzoptionen:</span>
                    <asp:RadioButtonList ID="rbloptions" runat="server" AutoPostBack="True" DataSourceID="sdsoptions" DataTextField="name" DataValueField="price">
                    </asp:RadioButtonList>
                    <asp:SqlDataSource ID="sdsoptions" runat="server" ConnectionString="<%$ ConnectionStrings:HamoConStr %>"
                        SelectCommand="SELECT * FROM TypeExtraPay WHERE type='extra' AND cat=1">
                    </asp:SqlDataSource>
                </div>
                <div class="col-md-12 alefbasystemdotcom">
                    <span style="font-weight: bold;">Verarbeitung und Veredelung:</span>
                    <asp:RadioButtonList ID="rblproccess" runat="server" AutoPostBack="true" DataSourceID="sdsproccess" DataTextField="name" DataValueField="price">
                    </asp:RadioButtonList>
                    <asp:SqlDataSource ID="sdsproccess" runat="server" ConnectionString="<%$ ConnectionStrings:HamoConStr %>"
                        SelectCommand="SELECT * FROM TypeExtraPay WHERE type='post' AND cat=1">
                    </asp:SqlDataSource>
                </div>
                <div class="col-md-12 alefbasystemdotcom">
                    <span style="font-weight: bold;">Angestrebter Liefertermin:</span>
                    <asp:RadioButtonList ID="rbldeliverydate" runat="server" AutoPostBack="true" DataSourceID="sdsdelivery" DataTextField="name" DataValueField="price">
                    </asp:RadioButtonList>
                    <asp:SqlDataSource ID="sdsdelivery" runat="server" ConnectionString="<%$ ConnectionStrings:HamoConStr %>"
                        SelectCommand="SELECT * FROM TypeExtraPay WHERE type='deliverydate' AND cat=1">
                    </asp:SqlDataSource>
                </div>
                <asp:Label Text="" ID="mylbl" runat="server" />
            </div>
        </ContentTemplate>
    </asp:UpdatePanel>
</form>

谢谢您的帮助
