radmenu - 禁用顶级菜单项的 radmenu 单击事件

Question

在我的代码中，

    MenuList = new Telerik.Web.UI.RadMenuItem();
    MenuChild1 = new Telerik.Web.UI.RadMenuItem();
    MenuList.Text = "Orders";
    MenuList.Value = "Orders";

    RadMenu_Control.Items.Add(MenuList);

    if (genRights.Find(delegate(UserRights u) { return u.RIGHT_NAME == "Group Master"; }) != null`enter code here`)
    {
        CategoryList = new Telerik.Web.UI.RadMenuItem();
        CategoryList.Text = "Purchase Order";
        CategoryList.Value = "order";
        MenuList.Items.Add(CategoryList);
        //MenuChild1 = new Telerik.Web.UI.RadMenuItem();
        //MenuChild1.Text = "PURCHASE ORDER";
        //MenuChild1.Value = "order";
        //MenuList.Items.Add(MenuChild1);
    }
    else
    {

    }

现在在这里我想禁用点击“订单”而不是“采购商订单”，因为它是子项目。

首先，您需要将事件“OnClientItemClicking”添加到您的 RadMenu。像这样:

<telerik:RadMenu ID="RadMenu1" runat="server" OnClientItemClicking="DisableRootClick">

这里是 DisableRootClick javascript 函数的主体:

function DisableRootClick (sender, args) {
    if (args.get_item().get_items().get_count() != 0 && args.get_item().get_level() == 0) {
            args.get_item().set_selected(false);
            args.get_item().set_focused(false);

            args.set_cancel(true); // Cancel the event
    } 

}

给你:)
