Increase UpdateCount property. If UpdateCount is larger than 0, updates such as component redraw, calculations, event calls etc. will be postponed until EndUpdate method is called and UpdateCount = 0.

procedure BeginUpdate(Options: TNxUpdateOptions = [uoScrollBar]);

Parameters

Options

TNxUpdateOptions

Specify type of updates that will still be processed.

Calling this method is recommended before heavily time consuming routines are started.

Example

try
  // Only events and scrollbars will be processed
  NextGrid61.BeginUpdate([uoEvents, uoScrollBar]); 

  // Time consuming routine
  for i := 0 to NextGrid61.RowCount - 1 do
  begin
    // code here
  end;

finally
  NextGrid61.EndUpdate; // Repaint and recount
end;
