Microsoft says (see below) that you can drop down a VB control. Anyone know how??
The built-in button is enabled for a column when its Button property is set to True.
Typically, you enable the column button when you want to drop down a Visual Basic control (such as the built-in combo box, a bound list box, or even another DataGrid control) for editing or data entry. When the button in the current cell is clicked, the ButtonClick event will be fired. You can then write code to drop down the desired control from the cell.
