#10 EditableHeader does not work with DataGrid

[Slawomir Procelewski]

If you implement EditableHeader for DataGrid after Sample 42 you get an error while Reght-clicking on the header.
Reason: sender.BeginEdit() invokes edit on the DataRowView with an index -1. I would await, that the appropriate column name was edited instead.

This is not exactly a bug. This is an unsupported feature.
I will move this to the "Feature Request" category.
