Hello,
I'm using BackstageViewControl with MVVM.
First problem is when data is loaded to model I see selected but not opened tab (Image 01). After loading data I set SelectedTab to null and IsOpen to false. For me will be good that this tab is not selected.
Second problem is when I clear data model and set SelectedTab to null and IsOpen to false, control pane area is not cleared (Image 03).
On Image 02 is visible what is control pane show when is selected first tab.
Here is code how I bind BackstageViewControl to model
XAML <dxr:BackstageViewControl x:Name="menuControl"
IsOpen="{Binding IsOpen,
Mode=TwoWay,
UpdateSourceTrigger=PropertyChanged}"
RibbonStyle="Office2010"
SelectedTab="{Binding SelectedMenuItem,
Mode=TwoWay,
UpdateSourceTrigger=PropertyChanged}"
TabPaneMinWidth="200">
<dxr:BackstageTabItem x:Name="btiMonitoring"
Content="{x:Static pres:Resources.mainMenuMonitoring}"
Visibility="{Binding MenuList_Monitoring_IsVisible,
Converter={StaticResource boolToVisibilityConverter}}">
<dxr:BackstageTabItem.ControlPane>
<dxlc:TileLayoutControl ItemTemplate="{StaticResource MenuTileTemplate}"
ItemsSource="{Binding MenuList_Monitoring}"
Style="{StaticResource MainMenuTileStyle}" />
</dxr:BackstageTabItem.ControlPane>
</dxr:BackstageTabItem>
...
