Please set the AutoExpandGroups property of RadGridView to true.

Is it possible to expand/collapse each group via a converter in the xaml (MVVM)?

In Silverlight 4 this cannot be achieved with simple style for the GridViewGroupRow since there are no bindings in the setters - you can simply set true or false:
<Setter Property="IsExpanded" Value="True" />
In Silverlight 5 this will be possible.
To achieve your goal with Silverlight 4 you will need to redefine the GridViewGroupRow template with Blend and attach your converter to the IsExpanded binding(s).
