TcxCustomImageList.CancelUpdate Method

Discards the postponed change notifications and allows the image list to send notifications to its listeners.

Declaration

delphi

procedure CancelUpdate;

Remarks

Every time a list change occurs, the image list sends notifications to its listeners and raises the OnChange event. Enclose multiple image list modifications between the BeginUpdate and CancelUpdate /EndUpdate procedure calls to avoid excessive listener updates. Unlike EndUpdate, the CancelUpdate procedure discards all pending notifications.

Note

A CancelUpdate or an EndUpdate procedure call should follow every BeginUpdate call, even if an exception occurs.
