Hello to all.
Sorry for my English.

I have the silverlight 5 app with your radgridview. (version - 2012.3.1017.1050). It's very powerful control for silverlight. But I have seen that there is the "memory leak".

As "ItemSource" I use the "QueryableCollectionView". My radgridview must updated every 5 second. (itemsource about 1000 items) I also set up the filtering and grouping  for "QueryableCollectionView". I have been seen that if I call "refresh" method there is memory leak about 3 MB per one update, but if I change item in QueryableCollectionView memory leak much less. Also I have been seen that if I call "this.radgrdiview1.ChildrenOfType<GroupHeaderRow>();" there are the collection of "GroupHeaderRow" which contains the item.Group == null, but if call QueryableCollectionView.Groups there aren't the group == null. Maybe this is the reason of memory leak?

I hope for a quick response.
Thank you advance.

With best regards, Vafin Ilgiz.
