I have several grids that are bound to large collections of objects that change frequently either from a background updater thread or by an edit in the xamgrid. For performance, and simplicity, I would like to use something like an ObservableDictionary<int, MyObject> to store the data where the key is a unique lookup value and the value is the object itself.
I can't figure out how to bind xamgrid to this type of data structure. Obviously, I can make an ObservableCollection<MyObject> off the dictionary Values but this is problematic in that to add update items you have to manually sync bptj the observablecollection and the dictionary.
Anyone else ever wanted to this.
Hello,

Thanks again.
Hi Stefan,
I tested it against 11.2.20112.2031 and can confirm that the grouping issue we were seeing in CAS-84326-PVWDJ0 has been fixed so I closed the ticket.
Any news on CAS-84644-XZF383 - that's the one that is going to hold us up if it doesn't get resolved?
Thanks!

Thanks for filing the bug. Upon further inspection, I think I may have found another unrelated bug in the same basic sample (see attached). To recreate the bug, click "Remove" (which will remove the last row in the grid), then click "Add" (which will add it back), then click "Update" which will increment the Age value by one for all values in the collection. Note how in the xamgrid, Update doesn't update the new last item - but if you switch to the "DataGrid" tab and try the same procedure in plain old datagrid it works as expected (note that each grid if bound to its own collection rather than the same one for simplicity).
