looks like you do this at the band level on the grid.

Can be done via the designer:

Control settings -> ultragrid -> displaylayout  then select the band you need to disable for...then  ColHeadersVisible =false;   (about 10 down)

code wise;

ultraGrid1.DisplayLayout.Bands[0].ColHeadersVisible = false;

where 0 is the index (or string)  for your band.

This will disable for all columns within the band.  Obviously if you have more than one band then you do it for each (if you want to do that).

Hope this helps.
