backgroundcolor in panels doesn't work

[ruud2000]

I try to set a background color for my panels like this:

Private Sub Panel14_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Panel2.Paint

        Panel2.BackColor = Color.LightGreen

    End Sub

But it doesn't work....why?

I found it.
I had to run the program to see the result.
