I have a xamGrid that shows the results from a query against a Entity Framework model context.  I use the query below:

var query = from o in vm.vdb.InventoryUSsingles                             

select o;

vm.USsingleGrid = new ObservableCollection<InventoryUSsingle>(query);

I have a database table that may have an update row so when I requery the context the xamGrid will close any open groups I may have then the user will have to reopen any previous groups that were open.  Is there a way to avoid this behavior?

Thanks,

Bryan K.
