Hello,

Could you give me a small example of what the code should look like when using the mouseposition.X and .Y in with teechart NET 2 and vb.net?

I have a popup menu that is called by right clicking on the chart but if I use the same code I used with the activeX version, it seems to get the wrong coordinates, and the menus/annotations do not show at the same point as the mouse.

Thanks!

J.E.T.

Hi J.E.T.,

You shouldn't use MousePosition for that. You can try doing the same in a UserControl without a TeeChart and you'll see it hapens the same. You should do something like the code below, it is the same using VB.NET.

Code: Select all

    private void tChart1_MouseDown(object sender, MouseEventArgs e)
    {
      X = e.X;
      Y = e.Y;
      tChart1.Invalidate();
    }

    private int X, Y;

    private void tChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
    {
      g.TextOut(X, Y, "hello");
    }
