How to reproduce:

1. RadGridView control with two group levels. One group row in every second level groups. All groups are initially collapsed.
2. Expand the first group. The group row of its child group is created and the ViewCellFormatting event is raised for it. Collapse the group.
3. Expand the second group. The group row of the first child group is reused for the group row of the second child group. The ViewCellFormatting event is not raised for it.
