The width of the list portion of the combobox.

Property of

ComboBox

Description

The width of the drop-down list of a combobox may be different than the width of the text entry portion. If dropDownWidth is zero (the default), the width of the drop-down list is sized to match the width of the control. Otherwise, the combobox’s dropDownWidth setting is used.

The dropDownWidth is expressed in the form’s current metric units (the same as the width).
