Combobox Controls

Overview

A combobox is (usually) a combination of an edit control and an associated listbox.  You can either type your data into the control directly, or you can select an item from the associated list.

A combobox looks like this:

There are three possible types of combobox:  

• An edit control with a drop-down listbox (which saves space on your panel)
• An edit control with a fixed-size listbox
• A dropdown listbox with no associated edit control 

Unlike a listbox, a combobox does not allow you to select more than one item
