RadGridView : Make Column unvisible and not selectable

[Nargis]

Hello,

I implement a WPF Application with RadGridView. Some columns are invisible and selectable. But I have also columns that must be unvisible and not selectable.
How could I achieve this behavior?

Thanks a lot in advance!
Best regards

I had the same issue and I resolved it manually creating a collection of selectable columns and then when I generate column I mark as invisible the columns that aren't in the collection.
