TdxGanttControlSheetColumns.BeginUpdate Method

Postpones all change notifications until an EndUpdate call.

Declaration

procedure BeginUpdate;

Remarks

Each time you apply a change to the column collection, the parent View normally repaints its area to reflect the changes. Enclose your code within the BeginUpdate/EndUpdate procedure blocks to prevent the Chart View Sheet or Resource Sheet View from multiple refresh operations and apply all changes at once.

Ensure that the EndUpdate procedure call follows every BeginUpdate procedure call, even if an exception occurs.
