im designing a form that updates a customer details. when the user enter an id, the form displays all the fields of that customer. my problem is that i have a combobox that displays the status of the customer, i filled the combobox with four items and when the user choose a customer, it displayed the correct value from the combobox. but when the user doesn't choose a value from the combobox, the comboxbox gets null instead of the value it was assign with. i want that if the user doesnt change the value in the combobox, the combobox will automatically gets the value it was assign with.
