Hello Kirk,

If the grid is just going to have standard textbox display instead of the listbox, then you might want to use the Form.Grid.Column1.Textbox1.MouseDown() event... Only problem, since a textbox allows you to use mouse down to highlight text, you will want to trap for (your choice), CTRL, ALT or SHIFT key. If it is set, and user clicks, you can activate the Drag() at that point. Then you can track via the record number and apply the drop as needed.

I have had to apply this technique on a current project and it works well.
Hope it helps.
