Hi Roi,

That's strange!!!
What's is value of the property ROWSOURCETYPE of the combobox?
If you're using = 5, then try the following:

- change that property to 0 (zero);
- create a method at the combo to populate "manually" the grid, like this:

NumColunas = Alen(&NomeArray, 1)
For i = 1 to NumColunas
For j = 1 to NumColunas
If Type("&NomeArray(i,j)") = "N"
this.AddListItem(Alltrim(Str(&NomeArray(i,j))), i, j)
Else
this.AddListItem(Alltrim(&NomeArray(i,j)), i, j)
Endif
Next j
Next i

- try this code, and try to change the COLUMNWIDTH now.

Perhaps the SQL statement (or the fact of having a ROWSOURCETYPE = 5) is affecting the columns widths. Don't know how to solve it, never happened to me.

Try this and day something, (and, of course, your opinion about this method).
