在listview控件中找不到按钮:(帮助 [英] Cannot find button in listview control :(Help

问题描述

您好，我想在listview控件中获取按钮，但我不知道，该怎么做。

我的ASP.NET代码：

Hello, i want to get button in listview control, but i don't know, how to do it.
My ASP.NET CODE:

<asp:ListView ID="lv_Links" runat="server" >

           <LayoutTemplate>
               <ul style="list-style: none;">
                   <asp:PlaceHolder ID="ItemPlaceholder" runat="server" />
               </ul>
           </LayoutTemplate>
           <ItemTemplate>
                <ul style="list-style: none;padding: 0;">
                  <li> <asp:HyperLink ID="LinkItem" runat="server" Text='<%# Eval("Description") %>'
                            NavigateUrl='<%# Eval("Link") %>'>
                            </asp:HyperLink>&nbsp;<asp:ImageButton ID="Button2" ImageUrl="~/_layouts/Portal.Croc.Box.Social.ForNewEmployee/i/delete.gif" itemid='<%# Eval("ID") %>'  OnClick="delete_Onclick" OnClientClick="return confirm('Вы действительно хотите удалить ссылку?');" Width="14px" Height="14px" runat="server"/> </li>

                  </ul>
               </ItemTemplate>
       </asp:ListView>

Code Behind：

Code Behind:

protected void Page_Load(object sender, EventArgs e)
       {
           SPWeb oWebs = SPContext.Current.Web;
               String Editors = "Новому сотруднику – модераторы";
           String Owners = oWebs.Site.RootWeb.AssociatedOwnerGroup.ToString();
           if (oWebs.SiteGroups[Editors].ContainsCurrentUser || oWebs.SiteGroups[Owners].ContainsCurrentUser)
           {
               HyperLink1.Visible = true;
               foreach (ListViewItem item in lv_Links.Items)
               {
                   ImageButton ddrList = (ImageButton)item.FindControl("Button2") as ImageButton;
                   ddrList.Visible = true;

               }
           }
           else
           {

           }
        }

但它不起作用：（帮助
