EVENTS ^

Common events apply to most windows and controls.

Change

Change()

Sent when the user selects an item from the Combobox

CloseUp

CloseUp()

Sent when the list box of a combo box has been closed. This event allows you to populate the dropdown dynamically. This event is only fired if the combo box has the CBS_DROPDOWN or CBS_DROPDOWNLIST style.

If the user changed the current selection, the combo box also sends the Change event when the drop-down list closes. In general, you cannot predict the order in which notifications will be sent. In particular, a Change event message may occur either before or after a CloseUp event.

DblClick

DblClick()

Sent when the user double clicks on an item from the Combobox

DropDown

DropDown()

Sent when the user selects the list box. This event allows you to populate the dropdown dynamically. This event is only fired if the combo box has the CBS_DROPDOWN or CBS_DROPDOWNLIST style.

GotFocus

GotFocus()

Sent when the control is activated.

LostFocus

LostFocus()

Sent when the control is deactivated.
