Navigate() function of RadFrame error

[xuan]

When i use Navigate() function of RadFrame control. I met  an error at Frame.Navigate(navi);:
"Root visual should be Panel". please helps me to solve that problem!
 public TemplateFrame()
        {
            InitializeComponent();
            NavigatePage navi = new NavigatePage(new Page());
            Frame.Navigate(navi);
        }
NavigatePage is created like that :

 public partial class NavigatePage : UserControl,IFrame
    {
        public NavigatePage()
        {
            InitializeComponent();
        }
        public NavigatePage(Page nextPage)
        {
            InitializeComponent();
           LayoutRoot.Children.Add(nextPage);
        }

Hello Xuan,

Can you please check if the application's RootVisual is set to RadFrameContainer:

private void Application_Startup(object sender, StartupEventArgs e)
        {
            this.RootVisual = new RadFrameContainer();
            NavigationService service = NavigationService.GetNavigationService();
            if (!NavigationService.LoadDeepLink())
            {
                service.Navigate(new Page1());
            }
        }
 
Note:
It is important that RadFrame must always be placed in RadFrameContainer! You can use RadFrame in this way:

    <telerik:RadFrameContainer>
                <telerik:RadFrame Source="Page2" Width="500" Height="300"></telerik:RadFrame>               
           </telerik:RadFrameContainer>

When you use navigation with RadFrame the navigation target is automatically set to the parent RadFrameContainer thet holds the frame.
