You can use it in LostFocus. In my case the reason was that I wanted code to fire without leaving my combobox control also.

No specific reasons, my combo I copied the code from had a RowSourceType = 1 (Value) :)

If you have buffering enabled then you will need to use TABLEUPDATE() somewhere also.

Well, Combobox and Grid are the most complicated and tricky controls in VFP, some workarounds we do for them should be just their native functions...
