How to do Listbox contraint/validation

What's the best way to put validation/constraints on a Listbox which is used in "select" mode (i.e: dropdown list) ?

Listbox doesn't have Constraint support like Textbox.

I want to check that the Listbox has a selected item other the first item (first item is empty space "").

I want to have popup error close to the Listbox similar to Textbox error popup.

Regards, cgunadi
