[Solved] ArgumentException on dragging a column header in ChildWindow

[Roman Kovac]

Hello,
we've created a sample project with 2 grids (version 2010 Q2), the first one is on a UserControl, the second one is on ChildWindow . Drag&Drop of a column header does work in UserControl, however it doesn't in the ChildWindow and it throws following exception:

System.ArgumentException: Value does not fall within the expected range.

Any ideas how to solve this issue?
Thanks in advance
