Only with respect to NumberOfElements according to the VFP Help. There is no such restriction on DisplayCount which does exactly what I wanted all along.

>OK, you have found the display count, but I don't understand why would you be limited to one column? My favorite trick is to manipulate the ColumnWidths so that the unwanted columns are invisible. Say I have a description in column 1 and a key in 2. In combo.init:
>

this.columnwidths=tran(this.width)+",0"
>this.boundcolumn=2
>this.boundto=.t.
