我使用textbox,checkboxlist,panel和popupcontrolextender创建了一个多选下拉列表控件。我已将所有控件放在UpdatePanel中。现在,当我检查CheckBoxList中的一个复选框时,CheckBoxList的SelectedIndexChanged被触发但是当我取消选中它时它不会被触发。但是,当我在我的给定代码中删除PopupControlExtender后尝试时,此事件正在正确触发。我认为PopupControlExtender导致了这个问题。关于这个的任何想法?

以下是代码:

<asp:UpdatePanel ID="updatepanelBizUnit" runat="server">
    <ContentTemplate>
        <asp:TextBox ID="txtBizUnit" runat="server" Width="147px" ReadOnly="true" TabIndex="1"></asp:TextBox>
        <asp:RequiredFieldValidator ID="valRequiredBizUnit" CssClass="validatorMessage" Display="Dynamic"
            ValidationGroup="VgroupPart" runat="server" ErrorMessage="The 'Business Unit' field is required."
            Text="*" ControlToValidate="txtBizUnit" ForeColor="" SetFocusOnError="True"></asp:RequiredFieldValidator>
        <asp:PopupControlExtender ID="txtBizUnit_PopupControlExtender" runat="server" Enabled="True"
            ExtenderControlID="" TargetControlID="txtBizUnit" PopupControlID="PnlBizUnit"
            OffsetY="14">
        </asp:PopupControlExtender>
        <asp:Panel ID="PnlBizUnit" runat="server" Height="116px" Width="145px" BorderStyle="Solid"
            BorderWidth="1px" Direction="LeftToRight" ScrollBars="Auto" BackColor="#FFFFFF"
            Style="display: none">
            <asp:CheckBoxList ID="ChkBizUnit" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ChkBizUnit_SelectedIndexChanged">
            </asp:CheckBoxList>
        </asp:Panel>
    </ContentTemplate>
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="ChkBizUnit" EventName="SelectedIndexChanged" />
    </Triggers>
</asp:UpdatePanel>
