Change the thickness of a certain grid line in DataGrid

Hi, I need to change the thickness of horizontal grid lines for every 32 grids (ie. the bottom border of 32nd, 64th, 96th row). It seems that DataGrid in WPFToolKit doesn't reveal any interface to let you change the thickness of certain lines. Any idea? Alvin
