What method can I override in GridViewHeaderRowPresenter to prevent it from drawing some columns?

Question

The thing is that I created a custom column that inherits from GridViewColumn, and I added a Visibility dependency property to it. Now I want to create a custom GridViewHeaderRowPresenter, that does not draw the columns when their visibility is hidden or collapsed, but other than the OnRender() method, I can't think of anything else.

Thanks.

Btw, the reason I'm doing this is because removing or adding columns doesn't work like we would expect it (some specs for our app) and I believe what I'm trying to do here would work if pulled out correctly.
