The easiest way would probably be to go into the grid control on the interface editing screen, edit the grid, go to options, and uncheck "show names in grid."

Then, so long as you don't do something like pass the name to the grid via a separate output() proc, the name shouldn't show up.

I really like that they added that checkbox. Prior to this, you'd have to create a separate object with a blank name (name = "") and have it act as an interface for the real object.
