I am using Delphi 4.  Does anyone know how to obtain the section index number if the section is clicked on with the RIGHT mouse button?

ie: in the OnSectionClick event it does not pass the mouse button pressed - only HeaderControl: THeaderControl;
  Section: THeaderSection are passed - and if i use the OnMouseDown event the section:TheaderSection is not passed.

Check this out: (You'll need to include CommCtrl in the uses)

procedure TForm2.HeaderControl1MouseUp(Sender: TObject;
  Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
var
  Index: Integer;
  Info: THDHitTestInfo;
begin
  if Button=mbRight then begin
    Info.Point.X := X;
    Info.Point.Y := Y;
    Index := SendMessage(HeaderControl1.Handle,HDM_HITTEST,0,Integer(@Info));
    { Index has the section index, or -1 if not }
    if Index>=0 then
      // change header to X position...just testing
      HeaderControl1.Sections[Index].text:=IntToStr(Info.Point.X);
  end;
end;
