You want to catch a dbl-click on a link?

You are correct we have no such event...

The workaround is to catch a normal-double click and see if that click started a mousemove operation that only comes if you click a link:

    private void gantt1_OnTimeItemAreaMouseDown(object sender, MouseEventArgs e)
    {
      if (e.Clicks == 2 && gantt1.MouseMoveKind==MouseMoveKind.linkReAssign)
      {
        gantt1.MouseMoveCancel();
        MessageBox.Show("Hey, dbl click on link");
      }
    }

Then we Cancel that started operation and bring up a dialog instead...
