title: DataGridView - Proportional Sizing
body: <p>I have a WinForm project with a tab control container and several tabs.  On 1 tab, I have 2 grids, one on top of the other.  The grids stretch all the way across the form when fully maximized or when floating (minimized but not hidden).  That part works exactly how I want it to.</p>
  
  <p>However, I want the grids to size proportionally on the vertical axis.  I cant find a way to set a % for the height of the grid.  Is there some other trick to achieving this?  Any tips on what property or combination that I might need to set or investigate?  Sorry, I know not much to go on, but any help would be appreciated.</p>
