TdxCustomMapControl.BeginUpdate Method
Prevents the map control from being repainted until the EndUpdate method is called.
Declaration
procedure BeginUpdate;
Remarks
Each time the layout/appearance options are changed, the map control initiates complete content repainting to reflect these changes. If you need to change several options at once, a sequence of painting updates occurs. To postpone these updates, enclose the code that modifies these options within the BeginUpdate/EndUpdate method blocks.
The BeginUpdate method postpones updates. To apply the changes made, call the EndUpdate method. Ensure that every call to BeginUpdate has a corresponding call to the EndUpdate method, even if an exception occurs.
