I have a RadGridView in my Silverlight application. I am using MVVM with this application.

I would like to show or hide a GridViewDataColumn column based on a bool property in my Model/ViewModel called ShowAuditColumn.

This works:

But I'd like to use the following. But nothing happens. Should the following work?

How can I hide of show a column and bind it to a bool property?

For your convenience, I prepared an example to demonstrate how to achieve the desired behavior. Please take a look at the implementation and consider how this approach fits your scenario.

You may take a look at this forum thread for more detailed information on the matter. 

I hope that this helps. Should you have any other questions, do not hesitate to contact us.
