Eliminate tab headers on subgrid

[Carl]

I'm trying to eliminate the tab that says table on the subgrids below. I've tried 

     template1.ShowChildViewCaptions = false;

     template1.MasterTemplate.ShowChildViewCaptions = false;

     grid.ShowChildViewCaptions = false;

     grid.MasterTemplate.ShowChildViewCaptions = false;

Nothing works. What am I doing wrong?

Thanks

Carl
