TdxCustomFlowChart.BeginUpdate Method

Forbids the control from repainting its area until an EndUpdate procedure call.

Declaration

procedure BeginUpdate;

Remarks

The flow chart control allows users to add or remove chart elements and customize their appearance and behavior. Each time you modify chart settings, the control repaints its area to reflect changes. To prevent the control from redundant repaint operations and apply all changes at once, call the BeginUpdate procedure beforehand, and call EndUpdate after you make changes.

Ensure that a CancelUpdate or EndUpdate call follows every BeginUpdate call, even if an exception occurs.
