RadioButtonList如下所示，没有自动回发 . 我的问题是当我选择选项1（值1）并单击任一链接按钮时，后面的代码中的变量NotifyMe始终为true，因为所选项始终是默认值 . 我试图为此RadioButtonList设置EnableViewState，并保留没有ViewState的表单重置 . 它也没用 . 谢谢您的帮助 .

<div id="preferencePopup" style="display: none" title="Set Preference">
  Select an option than click either of the button below.
  <div>
    <ul id="preferenceOptions">
      <li>
        <asp:RadioButtonList ID="PreferenceNotification" runat="server" CssClass="radioButtonNoBorder">
          <asp:ListItem Text="No notification" Value="1" />
          <asp:ListItem Text="Notification" Value="2" selected="true" />
        </asp:RadioButtonList>
      </li>
    </ul>
  </div>
  <div class="col-md-offset-1 col-md-11 col-sm-12 text-center">
    <asp:LinkButton ID="btnSavePreference" runat="server" OnClick="btnSavePreference_Click" CssClass="btn btn-default">Clear & Save</asp:LinkButton>
    <asp:LinkButton ID="btnAddAndSave" runat="server" OnClick="btnSavePreference_Click" CssClass="btn btn-default">Add & Save</asp:LinkButton>
  </div>
</div>

protected void btnSavePreference_Click(object sender, EventArgs e) {
  bool NotifyMe = PreferenceNotification.SelectedItem.Value == "2" ? true : false;
}
