Patty,

>My goal is to select a zip code from a combobox (which contains zip, city and state), and update a separate city textbox and state combobox from the selected combobox entry. The user has the option to overwrite the city and/or state.

>The code to place the default city and state into their respective objects is in the Leave of the combobox, and works fine. However, if I do not tab through the city and state objects before pressing the Save button, only the zip code change is saved. When I tab through these two textboxes, the changes to the city and state save ok.

It may be the way you're setting the value of the text boxes. I recommend checking out the MM .NET Dev Guide topic "How do I programmatically set the value of Windows Controls?".

Regards,
