    Hello,

    My suggestion for achieving a conditional column visibility is to handle Checked/Unchecked events of the CheckBox. There you can set the visibility of the field you choose. For example:
     private void CheckBox_Checked(object sender, RoutedEventArgs e)
        {
              this.grid.FieldLayouts[0].Fields["Height"].Visibility = Visibility.Collapsed;
        }

    In this case visible or hidden would be not only cells but the header as well.

    Another approach (if you do not watt to use this events and instead use binding like the code-snippet you provided) is to add overriding of the LabelPresenter style and to bind its Visibility property just like the cell's visibility. This will hide or show the column header.
    I have attached a sample application that demonstrate these approaches.
    If you require any further assistance on the matter, please let me know.
