DevExpress Quantumgrid Header Height

I have had a problem recently using a DevExpress Quantum Grid which has the column filters enabled and also the ability to drag and drop. I needed a way to get the header height so it would ignore the begindrag. The after trying a few things this is the best way I found to get the header height.

iHeaderHeight := GridView.ViewInfo.HeaderViewInfo.Bounds.Bottom -
      GridView.ViewInfo.HeaderViewInfo.Bounds.Top;
