Comments

The ItemDblClk event occurs when a mouse button is double-clicked.

¹⁾ If the AutoRespond property is set to True, the areas areaSftBoxButton, areaSftBoxItem and areaSftBoxCell do not generate an ItemClick event for the left mouse button. The combo box control responds by expanding/collapsing the items automatically. The middle and right mouse buttons still generate the event in those areas.

Double click events in the drop down portion only occur in a simple combo box or if during the preceding ItemClick event the DropDown.Suppress method was used to suppress showing/hiding the drop down portion. Drop down and drop down list combo boxes usually hide the drop down portion in response to the first mouse click, so a double click is not possible, unless the DropDown.Suppress method is used.

Once an ItemClick or ItemDblClk event is processed, the drop down portion may automatically become visible or may be hidden in response. This default action is built into the control. It is possible to suppress the default response by using the DropDown.Suppress method while handling the ItemClick or ItemDblClk event.

The edit control portion does not generate an ItemDblClk event. The MouseDblClk event can be used instead.

An ItemClick event always precedes the ItemDblClk event.
