[Solved] RadMenu not responding

[bohebolo]

I don't know if this a bug or not, but here is how to reproduce the behavior.

The xaml:

<UserControl x:Class="TestTelerik.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:compMod="clr-namespace:System.ComponentModel;assembly=System.Windows"
    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
    xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls assembly=Telerik.Windows.Controls.Navigation"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">

    <UserControl.Resources>
        <!-- mainMenu template -->
        <telerik:HierarchicalDataTemplate x:Key="mainMenuTemplate" ItemsSource="{Binding SubItems}">
            <telerik:ContainerBinding.ContainerBindings>
                <telerik:ContainerBindingCollection>
                    <telerik:ContainerBinding PropertyName="Icon" Binding="{Binding Icon}" />
                </telerik:ContainerBindingCollection>
            </telerik:ContainerBinding.ContainerBindings>
            <TextBlock Text="{Binding Text}" />
        </telerik:HierarchicalDataTemplate>

        <!-- mainMenu collectionViewSource -->
        <CollectionViewSource x:Name="mainMenuItemsSource">
            <CollectionViewSource.SortDescriptions>
                <compMod:SortDescription PropertyName="MenuID" Direction="Ascending"/>
            </CollectionViewSource.SortDescriptions>
        </CollectionViewSource>
    </UserControl.Resources>

    <Grid x:Name="LayoutRoot">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>

        <telerikNavigation:RadMenu x:Name="mainMenu" ClickToOpen="False" ItemTemplate="{StaticResource mainMenuTemplate}" VerticalAlignment="Top" Width="Auto" Grid.Column="0" Grid.Row="0" />
    </Grid>
</UserControl>

code behind:

public class MenuItem
{
    public MenuItem()
    {
        this.SubItems = new ObservableCollection<MenuItem>();
    }

    public int MenuID
    {
        get;
        set;
    }

    public string Text
    {
        get;
        set;
    }

    public Image Icon
    {
        get
        {
            return _icon;
        }
    }
    private Image _icon;

    public ObservableCollection<MenuItem> SubItems
    {
        get;
        set;
    }
}

public partial class MainPage : UserControl
{
    public MainPage()
    {
        StyleManager.ApplicationTheme = new Windows7Theme();
        InitializeComponent();
        LayoutRoot.Loaded +=new RoutedEventHandler(LayoutRoot_Loaded);
    }

    private void LayoutRoot_Loaded(object sender, RoutedEventArgs e)
    {
        ObservableCollection<MenuItem> col;

        MenuItem manageFormsMenu = new MenuItem()
        {
            MenuID = 100801,
            Text = "Manage Forms"
        };

        MenuItem getDataMenu = new MenuItem()
        {
            MenuID = 100803,
            Text = "Get Data"
        };

        col = new ObservableCollection<MenuItem>();
        col.Add(manageFormsMenu);
        col.Add(getDataMenu);

        MenuItem maintenanceMenu = new MenuItem()
        {
            MenuID = 100800,
            Text = "Maintenance",
            SubItems = col
        };

        MenuItem logoutMenu = new MenuItem()
        {
            MenuID = 100900,
            Text = "Logout"
        };

        col = new ObservableCollection<MenuItem>();
        col.Add(maintenanceMenu);
        col.Add(logoutMenu);

        MenuItem systemMenu = new MenuItem()
        {
            MenuID = 100000,
            Text = "System",
            SubItems = col
        };

        MenuItem stockInMenu = new MenuItem()
        {
            MenuID = 110101,
            Text = "Stock In"
        };

        col = new ObservableCollection<MenuItem>();
        col.Add(stockInMenu);

        MenuItem unitMenu = new MenuItem()
        {
            MenuID = 110000,
            Text = "Unit",
            SubItems = col
        };

        col = new ObservableCollection<MenuItem>();
        col.Add(systemMenu);
        col.Add(unitMenu);

        mainMenuItemsSource.Source = col;
        mainMenu.ItemsSource = mainMenuItemsSource.View;
    }
}

Now run it, click system - logout menu. Then hover on system - maintenance menu, and move the cursor to Unit menu.

FYI, i'm using 2010 Q1 SP1..

Hello Bohe,

I have tested your project with the latest DLLs and there are no problems. Would you consider upgrading to newer release version?
