    When the IsBackStageOpen has TwoWay binding to a boolean in the ViewModel, and the boolean's value is true, the Backstage misbehave. 

     This is the code of the VM

    namespace IsBackstageOpenBug
        public class MainViewModel : ViewModelBase
            private bool _isBackStageOpen = true;
            public bool IsBackStageOpen
                    return _isBackStageOpen;
                    _isBackStageOpen = value;



    This is the XAML

     <telerik:RadRibbonWindow x:Class="IsBackstageOpenBug.MainWindow"

            Title="MainWindow" Height="350" Width="525" >
            <telerik:RadRibbonView Name="MainRibbon" IsBackstageOpen="{Binding IsBackStageOpen, Mode=TwoWay}"
                ApplicationName="My App"
                    <TextBlock Text="Project" VerticalAlignment="Center" HorizontalAlignment="Center"/>
                    <telerik:RadRibbonBackstage telerik:KeyTipService.AccessText="F">
                        <telerik:RadRibbonBackstageItem Header="New" telerik:KeyTipService.AccessText="N" />
                        <telerik:RadRibbonBackstageItem Header="Open"/>
                <telerik:RadRibbonTab Foreground="Black" Header="Edit" telerik:KeyTipService.AccessText="E">
                    <telerik:RadRibbonGroup Header="Clipboard" />


    The ribbonview does open in backstage, as expected, but clicking on the "Edit" tab, selects that tab, but leaves  the backstage opened.

    Hello Benn,

    This is a known issue. I made the item public in our FeedbackPortal where you can track its progress. 

    In the meantime as a workaround you can set the property IsBackStageOpen from your MainViewModel to true on Loaded of the RibbonView:
    private void MainRibbon_Loaded(object sender, RoutedEventArgs e)
    vm.IsBackStageOpen = true;

    Please excuse us for any inconvenience caused.

    Do you want to have your say when we set our development plans? Do you want to know when a feature you care about is added or when a bug fixed? Explore the Telerik Feedback Portal and vote to affect the priority of the items
