Hi, Dragan

>Nope, it's not invisible and visible. It's invisible. What you see is the default textbox that Fox conjures instead of the invisible one, because that's what it does if you don't supply your own control. Or if your control is invisible.

In fact it _is_ both invisible and visible. Believe me. I tried it. < s > It's not the textbox that's visible, it's the checkbox.

DELETE FILE ROCheckbox.SC? RECYCLE

* Make a form
CREATE FORM ROCheckbox NOWAIT
LOCAL laObject[1], lo
ASELOBJ(laObject,1)

* Add a grid with 1 column
lo.ADDOBJECT('grid1','grid')
lo.Grid1.COLUMNCOUNT = 1

* Make a simple cursor so the grid has something
* to bind to. Note, though, that this isn't 
* necessary to trigger the issue.
lo.WRITEMETHOD("Load",;
  "CREATE CURSOR temp (l1 l)" + CHR(13) + ;

* Add code to the Grid's Init() to add a
