Loosing Selection in CollectionViewSource

[Ryan]

I have an applicaion with 1 to many tabs that are in viewModel to view fashion with the ViewModels contained in a CollectionViewSource.  This works great for other controls that I can start an edit, switch tabs an retrun with edits in place.  The gridView is not maintaining selection, sorting or filtering (I believe because  it is reinitializing) when the tab it is contained on looses and regains focus.
The grid looses filters, sorting and selection.

Hi Ryan,

I would like to know if you are using our RatTabControl or the one that comes with the framework? In case you are using RadTabControl you could try setting IsContentPreserved to False to force the control to preserve tab content. 

Let me know if that resolves the issue. 

All the best,

Sorry standard TabControl.  Is there a way to make it happen with the windows controls?

Hi Ryan,

I believe that this cannot be done with the default controls. Replacing TabControl with RadTabControl should be quite easy. You could do this for the sake of figuring out if the issues really comes from TabControl. 

Best wishes,
