StatusBar - Dynamic items and static items

I have a statusbar, which will contain some dynamic statusbaritems and some "hard-coded" statusbaritems. For some reason the dynamic status bar items are not displayed, even thought the binding with the ViewModel property is done and I can see the items using Live Visual Tree

This is the statusbar

<StatusBar x:Name="StatusBar" Grid.Column="2" Grid.Row="1" ItemsSource="{Binding}">
            <StatusBar.Background>
                <SolidColorBrush Color="White" Opacity="0.5"/>
            </StatusBar.Background>
            <StatusBarItem Height="60" Width="120" HorizontalAlignment="Right">
                <Image Source="Logo.png" ></Image>
            </StatusBarItem>           
            <Separator></Separator>        
            <StatusBar.ItemTemplate>                
                <DataTemplate>
                    <TextBlock Text="ASDF"></TextBlock>
                </DataTemplate>
            </StatusBar.ItemTemplate>
        </StatusBar>

enter image description here

This is the statusbar at runtime.

As you can see there are 5 items that are visible and 2 items from the observable collection that do not render on the UI.

This is how the UI looks enter image description here

The green/blue part is visible, the rest of the StatusBar space is taken by the last separator. My dynamic items are no where to be found.

Any ideas? Can I make both dynamic/static items work in the same StatusBar? Or do I need to add 2 statusbar one for dynamic and the other one for static content.

Solution

  • Can I make both dynamic/static items work in the same StatusBar?

    No. You cannot both bind to an ItemsSource and add static objects to the Items collection.

    If your binding would work, you would get an InvalidOperationException saying that 'Items collection must be empty before using ItemsSource.'

    What you should do is to add your static items to the source collection in your view model.
