I'm probably missing something completely obvious, but how do I notify the DataGridVirtualizingCollectionView  that the total number of readings has changed?

Hi Mike,

It will be picked up the next time QueryItemCount is called.

If I receive notification that the underlying data has had a new row added to the end, is there any better way to get it updated than calling DataGridVirtualizingCollectionView .Refresh which seems to force it to re-get all the rows it needs regardless of whether the new row needs displaying?

Any update on the best way to work with this collection?

Does the latest version allow you to bind to a collection that changes size (using the virtualisation stuff)?
