Carlos,

I have indeed tested it under VFP5 SP3, but jumped to an early conclusion based on the character vs. numeric value because you said it was returning char values.

After some more testing this morning, all you need to do is add a bit of code in the ProgrammaticChange method. Something like:

if ( this.Value < 0 )
   this.ListIndex = SomeAppropriateLookupFunction( this.Value )
endif

This will cause the cbo DisplayValue to show the correct item instead of blank. All along the cbo.Value was correct, it just wasn't displaying properly.

>I have done this from the beginning. I have 0 to initial value of the combo. But still doesn't works. I think you have not tested it. Thanks anyway.
