<asp:Content ID="PageContent" ContentPlaceHolderID="PageContent" runat="Server">
<div id="checkout_onePage" class="mainContentWrapper opcOverlayWrapper">
    <script language="javascript" type="text/javascript">

                                <div class="content floatleft">
                                    <asp:PlaceHolder ID="LoginPanel" runat="server" EnableViewState="False" Visible="false">

                                            to retrieve your saved addresses.
                                        </p>
                                    </asp:PlaceHolder>                                        
                                </div>
                            </ContentTemplate>
                        </asp:UpdatePanel>
                    </div>
                </Content>
            </ajax:AccordionPane>
            <ajax:AccordionPane ID="ShippingInformation" runat="server">
                <Header>
                    <div class="widget shippingAddressWidget aboveOpcOverlay">

                        </div>
                    </div>
                </Header>
                <Content>
                    <asp:Panel ID="ShippingAddressPanel" runat="server" Visible="true">
                        <div class="aboveOpcOverlay">
                            <div class="content" runat="server" id="Div_Main_Shipping_Information">

                            </div>
                        </div>
                     <table>
                     <tr id="trShippingAddress" runat="server" visible="false">
                                            <td>
                                                <uc2:AddressDetails ID="ShippingAddress" runat="server" ValidationGroupName="Shipping" />
                                            </td>
                                        </tr>
                                    </table>
                    </asp:Panel>
                </Content>
            </ajax:AccordionPane>
        </Panes>
    </ajax:Accordion>

我在上面的页面中分配了一个用户控件，我无法找到名为Div_Main_Shipping_Information的div控件

我的usercontrol代码如下

 Content PageContent = (Content)this.Parent.FindControl("PageContent");
 Accordion UserAccordion = (Accordion)PageContent.FindControl("UserAccordion");
 AccordionPane shipInfoPane = UserAccordion.Panes["ShippingInformation"];
 Panel ShippingAddressPanel = (Panel)shipInfoPane.FindControl("ShippingAddressPanel");
 System.Web.UI.HtmlControls.HtmlGenericControl Div_Main_Shipping_Information = (System.Web.UI.HtmlControls.HtmlGenericControl)ShippingAddressPanel.FindControl("Div_Main_Shipping_Information");

但我无法找到我的控制手风琴控制，面板控制或我的div控制。

Answer 1

using AjaxControlToolkit;

Accordion userAccordion = (Accordion)this.Page.FindControl("UserAccordion");
AccordionPane shipInfoPane = userAccordion.Panes["ShippingInformation"];
Panel ShippingAddressPanel = (Panel)shipInfoPane.FindControl("ShippingAddressPanel");
System.Web.UI.HtmlControls.HtmlGenericControl Div_Main_Shipping_Information = (System.Web.UI.HtmlControls.HtmlGenericControl)ShippingAddressPanel.FindControl("Div_Main_Shipping_Information");

无法从手风琴中设置的父页面中找到UserControl中的控件
