<ListView x:Name="ProgressListView" Grid.Row="1" Grid.RowSpan="2" ItemsSource="{Binding ProgressCollection}" Background="Transparent" Panel.ZIndex="10" IsHitTestVisible="False">
<!-- Omitted WPF for the progress units -->

<Button Grid.Row="0" Grid.Column="1"

• I have experimented with overriding the hittest of the listview, so I can ignore hittest in code but allow the button to be pressed. This did not work, but I am still looking into this.
• I have tried fiddling with the ZIndex on the Button, but if the listview ZIndex is lower that the rest, then buttons inside it will of cause also be behind it, no matter the buttons ZIndex. Its a part of the ListView.
• I have also looked into the Adorner layer. I find that this could probably work, but it will require a complete rewrite of the logic and as I understand it is not really what it is meant for and will be very complicated.
