How to get or compute actual width of ListBox without Vertical Scrollbar if visible

• I wonder how to get or compute actual width of ListBox without Vertical Scrollbar if visible. What I want to do is changing width of each items inside ListBox without being covered by Vertical Scrollbar. Width="{Binding ActualWidth, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBox}}} At least, above binding tell me the actual width of ListBox, but this one does not handle width of vertical scrollbar. Is there any good way to solve this?

• Answer:

  Try binding to the ViewportWidth property of the containing ScrollViewer instead. Like this: Width="{Binding Path=ViewportWidth, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ScrollViewer}}"
