Edit Question
Title
Body
According to the documentation , the Count of a filtered CollectionView should only be the count of items that pass the filter. Given this code: List<string> testList = new List<string>(); testList.Add("One"); testList.Add("Two"); testList.Add("Three"); testList.Add("1-One"); testList.Add("1-Two"); testList.Add("1-Three"); CollectionView testView = new CollectionView(testList); int testCount1 = testView.Count; testView.Filter = (i) => i.ToString().StartsWith("1-"); int testCount2 = testView.Count; I would therefore expect testCount1 to be 6, and testCount2 to be 3. However, both are 6. If I manually iterate through the CollectionView and count the items, I do get 3, but Count returns 6 always. I've tried calling Refresh on the CollectionView, just to see if that would correct the result, but there was no change. Is the documentation wrong? Is there a bug in CollectionView? Am I doing something wrong that I just can't see?
