Hi people.


To your knowledge, what could cause the ScrollIntoViewAsync to freezes there ?  I tried in a reproduction project but with less events and it's not reproducible.  There's something in my project that make the ScrollIntoView freezes.



What I do to make it freezes is adding a new row, cancelling it and then copying an existing row and when I copy a row I have code that clone the object and add it to the collection, then I do rebind the grid and use the ScrollIntoViewAsync to go to that row.



If I just copy immediately without adding a new row, the ScrollIntoViewAsync will not freeze.  It's just when I do add a new row and cancel then my next operation of copy and scrolling freezes

I tried removing the code that scroll and what I see is that my copy isn't added to the collection or visually it's not appearing.  I'll try other things to isolate the culprit

Well, it's not the ScrollIntoViewAsync the problem.  It looks like the grid is in some kind of coma when I click the "Click here to add a new row" and cancel it.  After that I'm unable to add a new object to my collection programmatically and have the grid showing it.

I managed to find the cause.  It was because grid Items collection was a subset of the complete collection because at some point in code I did a grid.ItemSource = MyCollection.Where(...);
