TdxTreeCustomNode.BeginUpdate Method

Prevents node owner updates until an EndUpdate call.

Declaration

procedure BeginUpdate;

Remarks

Every time the node’s properties change, the node owner redraws its client area. Enclose multiple node changes between the BeginUpdate and EndUpdate procedure calls to improve performance and prevent the node owner from flickering.

Note

An EndUpdate procedure call should follow every BeginUpdate call, even if an exception occurs.
