Icon BeginUpdate Method

procedure BeginUpdate

Available In: Visual Client Applications

Use this method to begin a batch update on a control. A control is in a batch update if the BeginUpdate method is called on the control, or any of its parent controls. When a control is in a batch update, it doesn't apply any changes to any of its properties until the EndUpdate method is called on the control or any of its parent controls, and the InUpdate property returns False.

Information Updates are reference-counted so calls to the BeginUpdate method increment the reference count, and calls to the EndUpdate method decrement the reference count.
