In my program I cycle through all of the columns that I'm adding to the grid, and do a RemoveObject("Text1") to remove the TextBox control that is placed there by default, then then AddObject("Text1", "blah") to add in my custom version of the TextBox control.

Basically, you did everything right, but, unfortunately, it seems that grid gets corrupted somewhere in the middle. You know, grids used to be corrupted when there are too many on-fly re-buildings. IMO, the better way to have a solid grid is to create it in form designer as a first place and permannently base on read/write cursor. Then, whatever interface solutions you want to apply to this grid, it will be actually repopulating (DELETE/ZAP/INSERT) of this cursor.
