Display RadRibbonView Backstage Open by default

[Ian]

Hi, 

Im working on a WPF application using the RadRibbonView. Our workflow is such that we would like the BackStage to be displayed open when the app is first launched so the user can choose to create a new project or open an existing one.

We have set 'IsBackStageOpen' to true in the XAML of the RadRibbonView, and the BackStage is displayed on load. However, it is not possible to interact with it. Clicking on a BackStageItem or anywhere closes the backstage and the users action is lost. Im not able to upload the project, however this is the XAML:

<Window x:Class="RibbonViewBackstageOpen.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
Title="MainWindow" Height="350" Width="525">
<Grid x:Name="RootGrid">
      <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
      </Grid.RowDefinitions>

<!-- Backstage defaults to Open -->
      <telerik:RadRibbonView x:Name="ribbonView"
          ApplicationName="TEST" Title="TEST" IsBackstageOpen="True" BackstageClippingElement="{Binding ElementName=RootGrid}">
        <telerik:RadRibbonTab Header="Test">
                <telerik:RadRibbonGroup Header="Test">
                    <telerik:RadRibbonButton Content="Test" />
                </telerik:RadRibbonGroup>
            </telerik:RadRibbonTab>
        <telerik:RadRibbonView.Backstage>
          <telerik:RadRibbonBackstage>
          <telerik:RadRibbonBackstageItem Header="Save" IsSelectable="True"/>
          <telerik:RadRibbonBackstageItem Header="Open" IsSelectable="True"/>
          </telerik:RadRibbonBackstage>
        </telerik:RadRibbonView.Backstage>
        </telerik:RadRibbonView>
    </Grid>
</Window>

If it is possible, what is the correct way to automatically display the backstage when an application is first run?

Thanks
Ian

Hi Ian,

 Indeed, this appears to be a bug in the RadRibbonView. We logged it in our PITS where you can track its status and we also updated your telerik account points as a thanks for your cooperation.

I'm having this same problem. When is it going to be fixed?

Hello David,

This is already fixed. Can you try it with the latest version of UI for WPF and let me know if the issue still occurs? If so, I would ask you to open a new support ticket and send a runnable project that reproduces the issue.

My WPF application is a separate assembly from the one containing the window. It creates the window, calls Show, and then calls another method which sets the IsBackstageOpen = True.

I worked-around the problem by running after Show,

Application.Current.Dispatcher.Invoke(Sub() Exit Sub, priority:=Windows.Threading.DispatcherPriority.Background)

This gives the UI time to show the window before setting the backstage.
