Try this on for size:

unit Unit1;
 
interface
 
uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ComCtrls;
 
type
  TTrackBar = class(ComCtrls.TTrackbar)
  protected
    property OnMouseUp;
  end;
 
  TForm1 = class(TForm)
    TrackBar1: TTrackBar;
    procedure TBMouseUp(Sender: TObject; Button: TMouseButton;
      Shift: TShiftState; X, Y: Integer);
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;
 
var
  Form1: TForm1;
 
implementation
 
{$R *.dfm}
 
procedure TForm1.TBMouseUp(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
begin
  ShowMessage(IntToStr(x) + ':' + IntToStr(y));
end;
 
procedure TForm1.FormCreate(Sender: TObject);

inampudi1, Have you had time to try the code?

It simply publishes the OnMouseUp for the trackbar control.
