我有一个 RadMenu，我希望在单击时突出显示选定的项目。但我无法得到想要的结果......

下面是我在 ascx.cs 文件中的代码：

命名空间 HGS.HGSAdmin.UserControl { 公共部分类 UCLeftMenu : System.Web.UI.UserControl { protected void Page_Load(object sender, GridItemEventArgs e) {

        RadMenuItem item = RadLeftMenu.FindItemByUrl(Request.Url.PathAndQuery);
        if (item != null)
        {
            Response.Write(item.Text);
            foreach (RadMenuItem childItem in item.Menu.GetAllItems())
            {
                childItem.CssClass = "";
            }

            item.CssClass = "focused";

            while (item.Owner is RadMenuItem)
            {
                ((RadMenuItem)item.Owner).CssClass = "focused";
                item = (RadMenuItem)item.Owner;
            }

        }
    }


    protected void RadLeftMenu_ItemClick(object sender, RadMenuEventArgs e)
    {
        foreach (RadMenuItem childItem in e.Item.Menu.GetAllItems())
        {
            childItem.CssClass = "";
        }

        e.Item.CssClass = "focused";

        RadMenuItem item = e.Item;
        while (item.Owner is RadMenuItem)
        {
            ((RadMenuItem)item.Owner).CssClass = "focused";
            item = (RadMenuItem)item.Owner;
        }

    }
}

}

下面是我的 ascx 页面：

                </Items>
            </telerik:RadMenu>
        </td>
</table>

任何人都可以请指导吗？非常感谢！

您可以通过 RadMenu 的 HighlightPath() 函数轻松实现此目的。以这个 Telerik 演示为例。
