How to make an ownerdraw Trackbar in WinForms

Question

I\'m trying to make a trackbar with a custom graphic for the slider thumb. I have started out with the following code:

namespace testapp
{
    partial class          


        

Answer 1

I've solved it by setting the UserPaint style in the constructor like so:

public MyTrackBar()
{
    InitializeComponent();
    SetStyle(ControlStyles.UserPaint, true);
}

OnPaint now gets called.
