This is from the top of my head, but you could override the paint process of the combobox, so that the background will be painted every time 1% is completed.

I'm afraid that it's not going to be simple. The ComboBox doesn't support custom drawing. I think you'd have to use some involved API calls, exactly which I don't know.

But, can't you just repaint the background of the CB?

The ComboBox.Paint event is hidden from the designer because it's not supported. I just tried this:

Public Class ComboBoxEx
    Inherits ComboBox
 
    Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
        MyBase.OnPaint(e)
 
        e.Graphics.DrawRectangle(Pens.Blue, 0, 0, 25, 25)
    End Sub
 
    Protected Overrides Sub OnPaintBackground(ByVal pevent As System.Windows.Forms.PaintEventArgs)
        MyBase.OnPaintBackground(pevent)
 
        pevent.Graphics.DrawRectangle(Pens.Red, 0, 0, 25, 25)
    End Sub
 
End Class

and placed an instance on a form and saw no blue or red square. As I said:

The ComboBox doesn't support custom drawing.
