>Sorry, default is 0 - Dropdown Combo. Other choice is 2 0 Dropdown List. Only thing that "works" is to set Column1.Sparse = .F., but that is ugly.

Mmm, ugly...

Rex, if I understood, you want some like this:

Mass clinc && like simply TextBox
Immunization && like _ComboBox_
Wasted && like TextBox again

Is this right?
If yes, I think that it impossible, at least with ordinary Grid, because you need change Column.ControlSource "in fly".
