Is there anyway to change the SpanCount in the Xaml if your using a tablet instead of a handset?
<telerikListView:ListViewGridLayout Orientation="Vertical" SpanCount="3" GroupHeaderLength="40">
3 is fine for mobile devices but for tablet 6 would make more sence. I tried OnIdiom but I don't think you can use that approach.
<OnIdiom x:TypeArguments="View">
<OnIdiom.Phone>
