You could derive from DataGridColumnStyle (or one of the derivative classes to avoid extra work) and override the Width property so that the set accessor does nothing. You'll have to have an internal property or a param in the constructor so you can set the initial width, though, which you can do by setting base.Width. This works in a quick test but still allows the user to drag the splitters (just doesn't actually change the width).

Upon inspection, the members you'd need to override are both private and are not virtual, nor do they use anything relevent that is overridable.

About the only thing I can think of is to override WndProc and handle mouse messages over the column header (which you can get the bounds of through various properties), not passing those to the base.WndProc.
