>Hi Fabio,

>I found the source of the problem. The code works fine as it is as long as the field value is in the combo's rowsource. If, for example, I have an empty value in my field and it's not in the list of possible choices, in some cases I may have the incorrect appearance. So, for these combos I just have to add a blank value to the list and everything worked as expected.

On your code you hide all the columns 2,3....
If this is the case, then set Columncount=0
and VFP implement the perfect choice:

width=IIF(BETWEEN(combo.width-defaultpopup.width,1,DRESSPOPUPMARGIN),defaultpopup.width)

With ColumnCount#0 vfp have various bugs.
