procedure TMyForm.dxDashboardControl1DesignerFormShow(ASender: TObject; AForm: TForm);
begin
  AForm.Caption := 'My Dashboard Designer';  // Changes the Dashboard Designer form caption

void __fastcall TMyForm::dxDashboardControl1DesignerFormShow(TObject *ASender, TForm *AForm)
{
  AForm->Caption = "My Dashboard Designer";  // Changes the Dashboard Designer form caption
  AForm->WindowState = wsNormal;             // Switches from maximized to the normal form state
  AForm->Position = poScreenCenter;          // Centers the dialog on the screen
