I have a Combobox that shows names of customers of a table. When
oppening it, the user MUST type the initial letter of the name so the
combo will be loaded only with names starting with the typed letter.
When oppening the combo I need validating if something was typed. If
nothing was typed a message must be sent and the Combo must remain
closed. How do I implemet this since when I show the message the combo
is automatically dropped down?? Thanks!
