InvalidateData on subroot level
posted

Hi,

Could you please help me with XamGrid.InvalidateData ?

I have Hierarchical grid:

RootItem1
  - Sub Items... <-- I can set GroupBy to those.
RootItem2....

I'm raising xamGrid.InvalidateData(true) when grid viewModel updates - but this procedure also is resetting groups collapse/expand state in all items.

Is there a way to InvalidateData on subitems of only specific RootItemX node (expecting that groups in other RootItems would preserve correct state)?
