paint an inherited control
<p>I have a class in my project, that inherits from Control and contains a few other items inside a groupbox:</p>

<pre><code>class ProgressControl : Control
{
    private GroupBox TrackGroupBox;

    //some other stuff
}
</code></pre>

<p>I have overridden the Width, Top, Left etc top affect the groupbox and subitems. How Do I paint the groupbox when I do something like:</p>

<pre><code>Panel.Controls.Add(ProgressControlInstance)
</code></pre>

<p>?</p>
