C# <；asp.net菜单控件>；所选项目样式表无法应用,c#,html,asp.net,asp.net-mvc,C#,Html,Asp.net,Asp.net Mvc,我面临一个奇怪的问题，无法将样式表添加为选定项：我的html如下所示： <asp:Menu ID="Menu2" runat="server" Orientation="Horizontal" DisappearAfter="10" CssClass="art-hmenu" DataSourceID="XmlDataSource1" IncludeStyleBlock="false" StaticEnableDefaultPopOu

我面临一个奇怪的问题，无法将样式表添加为选定项：

我的html如下所示：

<asp:Menu ID="Menu2"
    runat="server"
    Orientation="Horizontal"
    DisappearAfter="10"
    CssClass="art-hmenu"
    DataSourceID="XmlDataSource1"
    IncludeStyleBlock="false"
    StaticEnableDefaultPopOutImage="False">
    <StaticSelectedStyle CssClass="selected"/>
    <DataBindings>
        <asp:MenuItemBinding DataMember="Item" NavigateUrlField="Url" TextField="Text" />
    </DataBindings>
</asp:Menu>
<asp:XmlDataSource ID="XmlDataSource1" runat="server" />

  public partial class Menu : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            SelectRighMenuItem();
        }
    }

    /// <summary>
    /// 
    /// </summary>
    void SelectRighMenuItem()
    {
        string appDataPath = HttpContext.Current.Server.MapPath("~/App_Data");
        this.XmlDataSource1.DataFile = appDataPath + "\\" + GetRole() + "_menu.xml";
        this.XmlDataSource1.XPath = @"/Items/Item";
    }

    protected string GetRole()
    {
        string role = string.Empty;
        role = Session["Roles"].ToString();
        return role;
    }

}

但这是行不通的

我还尝试设置StaticSelectedStyle！！但也不起作用

我使用的样式表是：

/* menu structure */

艺术华萌来自哪里？我没有在标记中看到它？使用chrome inspect元素查看页面上呈现的实际结构，这可能有助于我更新问题！通过Chrome控制台检查页面上没有javascript错误（希望您有Chrome！），如果没有，则尝试使用$（“.art hmenu”）。单击（function（）{alert（“Hello click”）；}）；是的，我检查了所有内容，更多关于我所做工作的更新如下：
