Description
Occurs when the ItemIndex property changes as a result of a user selecting a different item.
Write an OnChange event handler to respond to changes of the ItemIndex property. OnChange allows a response once the list has been successfully changed.
OnChange is an event of type TNotifyEvent. If you want to wait for the list to be repainted to reflect the change, see OnChangeRepainted.
- Note: The OnChange event does not occur when you change the ItemIndex property from code. That is the intended functionality. If you want to replicate the behaviour of a user selecting a different item, call OnChange explicitly.
