Posted 29 January 2020, 9:35 am ESTI'm trying to use a FlexGrid on a secondary view and that works fine.
When I try to add a CollectionView to group items the secondary view crashes when I create 2 views with a Xaml error:
The application called an interface that was marshalled for a different thread. (Exception from HRESULT: 0x8001010E (RPC_E_WRONG_THREAD))
We have other issues with other controls C1DropDown but this one there is no work around.
Attached is the Microsoft Sample MultipleViews app with a demo flexgrid.
Note: If I set List<> directly on ItemSource it works fine.
