            //联系方式回报绑定
            LVC.DataSource = Cresults;
            LVC.DataBind（）;        }
    }
 

解决方案

我的解决方法是不使用从2012年VS拖放菜单我一个jQuery菜单即写道，此后便没有问题，更换这一点。

I have a asp:menu that stops functioning after I perform a search on my page. The search uses a update panel and is triggered by a submit button. Once the results are displayed on the page the menu hover effects stop working. It will no longer expand down on mouseover. The clickable links still work.

The menu is in the site's master page and is outside the update panel of the search control.

Thank you for any help!

This is the menu

  <asp:Menu ID="Menu5" runat="server" 
                                        DynamicEnableDefaultPopOutImage="False"
                                         Orientation="Horizontal"
                                         RenderingMode="List"
                                         StaticEnableDefaultPopOutImage="False"
                                         StaticPopOutImageUrl="~/Images/DownArrow.png"
                                         Visible="False" Font-Bold="False" ForeColor="Black">

                                        <Items>
                                            <asp:MenuItem PopOutImageUrl="~/Images/bullet.png" Selectable="False" Text="Add" >
                                                <asp:MenuItem Text="Item" NavigateUrl="~/Admin/CreateItem.aspx" ></asp:MenuItem>
                                                <asp:MenuItem Text="Contact" NavigateUrl="~/Admin/CreateContact.aspx" ></asp:MenuItem>
                                            </asp:MenuItem>
                                            <asp:MenuItem Text="Update" Selectable="False" Value="Update">
                                                <asp:MenuItem Text="Item" NavigateUrl="~/Admin/UpdateItem.aspx" Value="Item"></asp:MenuItem>
                                                <asp:MenuItem Text="Contact" NavigateUrl="~/Admin/UpdateContact.aspx" Value="Contact"></asp:MenuItem>
                                            </asp:MenuItem>
                                            <asp:MenuItem Text="Approve" Selectable="False"  Value="Approve" >
                                                <asp:MenuItem Text="Item" NavigateUrl="~/Admin/ApproveItem.aspx" Value="Item"></asp:MenuItem>
                                                <asp:MenuItem Text="Contact" NavigateUrl="~/Admin/ApproveContact.aspx" Value="Contact"></asp:MenuItem>
                                            </asp:MenuItem>
                                        </Items>
                                         <StaticMenuItemStyle HorizontalPadding="10px" />
                                    </asp:Menu>

This is the Button Click event

  protected void btnSubmit_Click(object sender, EventArgs e)
    {
        if (Page.IsValid)
        {


            string keyword = txtSearch.Text.Trim();
             List<dynamic> results = SearchItems(keyword);
             List<dynamic> Cresults = SearchContacts(keyword);




            //bind and return
            lv.DataSource = results;
            lv.DataBind();


            //Contact Bind return
            LVC.DataSource = Cresults;
            LVC.DataBind();

        }
    }

解决方案

My solution is not to use the drag and drop menus from VS 2012. I replaced this with a Jquery Menu that wrote and have had no issues since.
