TActiveListBox

API Manual

TActiveListBox is the active counterpart to the original TListBox control.

The AutoPostBack property is set to true by default. Thus, when a list item is clicked a OnCallback event is raised after OnSelectedIndexChanged event.

With ActiveControl.EnableUpdate set to true (default is true), changes to the selection will be updated on the client side.

Please refer to the original documentation of TListBox for usage.
