Removes a range of visual objects from the VisualCollection.
Assembly: PresentationCore (in PresentationCore.dll)
The visual objects that follow the removed objects are shifted to occupy the vacated positions, and their index values are updated.
The method also removes the parent-child relationships between the parent visual, which is the owner of the VisualCollection, and the range of child visuals.
If you need greater low-level control over the underlying storage implementation of visual child objects, consider using the AddVisualChild and RemoveVisualChild methods. When you use these methods, you define your own storage implementation, and do not use VisualCollection.
