CheckBoxList –成功，RadioButtonList –失败
[英]CheckBoxList – success, RadioButtonList – failure
问题描述
CheckBoxList和四个RadioButtonLists位于与AjaxToolKit中的不同ModalPopupExtenders关联的不同面板中的同一.aspx文件中。 我不处理他们的SelectedIndexChanged事件。 列表元素的状态在按钮事件处理程序中进行了测试； 这些按钮也位于这些面板中。 CheckBoxList元素（在'cblFlter'中）的状态会传递到带有复选框列表的面板中的OK按钮的处理程序。 RadioButtonLists元素的状态（从'obl0'到'obl3'）不会传递到带有单选按钮列表的面板中的OK按钮的处理程序：调试c＃代码时，所有这四个代码始终具有其无论在单击“确定”之前我单击了哪个单选按钮，并且无论在标记中为每个单选按钮列表设置的“选择”属性都不同，都会选择第一个单选按钮。

如Martin Ullrich所建议的那样，通过将'Value'属性添加到每个RadioButtonList ListItem中来解决问题，就像这样（一个RadioButtonList中的每个ListItem的value属性必须不同）：
<div id="ModPopExtSorting">
<asp:LinkButton ID="LinkButton3" runat="server" Text="T" CssClass="displayNone" />
<ajaxToolkit:ModalPopupExtender ID="ModPopExtSort" runat="server"
TargetControlID="LinkButton3" PopupControlID="MPE_PanelSort"
BackgroundCssClass="background" />
<asp:Panel ID="MPE_PanelSort" runat="server" CssClass="popup" style="display:none;" HorizontalAlign="Center">
<table class="center-block">
<tr>
<th></th><th> </th>
<th>Sort Priority</th>
</tr>
<tr>
<td>Date</td><td></td>
<td><asp:RadioButtonList ID="obl0" runat="server" RepeatColumns="4" RepeatDirection="Horizontal" RepeatLayout="Table" TextAlign="Left">
<asp:ListItem Selected="True" Value="1"/>
<asp:ListItem Value="2"/>
<asp:ListItem Value="3"/>
<asp:ListItem Value="4"/>
</asp:RadioButtonList>
</td>
</tr>
<tr>
<td>Vendor</td><td></td>
<td><asp:RadioButtonList ID="obl1" runat="server" RepeatColumns="4" RepeatDirection="Horizontal" RepeatLayout="Table" TextAlign="Left">
<asp:ListItem Value="1"/>
<asp:ListItem Selected="True" Value="2"/>
<asp:ListItem Value="3"/>
<asp:ListItem Value="4"/>
</asp:RadioButtonList>
</td>
</tr>
<tr>
<td>Status</td><td></td>
<td><asp:RadioButtonList ID="obl2" runat="server" RepeatColumns="4" RepeatDirection="Horizontal" RepeatLayout="Table" TextAlign="Left">
<asp:ListItem Value="1"/>
<asp:ListItem Value="2"/>
<asp:ListItem Selected="True" Value="3"/>
<asp:ListItem Value="4"/>
</asp:RadioButtonList>
</td>
</tr>
<tr>
<td>Amount</td><td></td>
<td><asp:RadioButtonList ID="obl3" runat="server" RepeatColumns="4" RepeatDirection="Horizontal" RepeatLayout="Table" TextAlign="Left">
<asp:ListItem Value="1"/>
<asp:ListItem Value="2"/>
<asp:ListItem Value="3"/>
<asp:ListItem Selected="True" Value="4"/>
</asp:RadioButtonList>
</td>
</tr>
</table>
<p> <asp:Button ID="pbSortOK" runat="server" Text="OK" OnClick="pbSortOKCancel_Click" />
<asp:Button ID="pbSortCancel" runat="server" Text="Cancel" OnClick="pbSortOKCancel_Click" />
</p>
</asp:Panel>
</div>
注释：我无法在https://docs.microsoft.com/zh-cn/dotnet/api/system.web.ui.webcontrols.radiobuttonlist?view=netframework-4.7.2中找到有关此文档； 在“声明性语法”下，在ListItem下提到了Value属性，但没有迹象表明在PostBack上确定所选元素是必需的（根据Martin Ullrich的研究）。
