I always have problems with a ListView inside a dynamic layout control like a Stackpanel.
Right now I have a Window with a Stackpanel as Root-Control. The Stackpanel str
This has nothing to do with the ListView. It is the StackPanel's "fault". In a StackPanel the child items always consume only the space they need (in the direction of the orientation of the StackPanel). That's how the StackPanel is designed. Use a DockPanel instead, there you can make the last item fill up all the space that is left over using LastChildFill="true"
(true
is default, so no need to explicity specify it).
