I found this thread but this is more than a year old and I'm using the latest version  Has anything changed to fix the issue? Is there another attribute I should be using to get the desire effect? Or do I have to use reflection, test for Browsable attribute and set AllowHiding on related field? Seems like a lot of work and I got tons of grids in my app that will have to run that code. Would just be easier if there was a setting to hide both from grid and field window. That way I can use style to set the property on all grids once. Or default it that way.
