If your context menu is a ContexMenuStrip
, you can create an item in this way:
[ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.MenuStrip |
ToolStripItemDesignerAvailability.ContextMenuStrip)]
public class TrackBarMenuItem : ToolStripControlHost
{
private TrackBar trackBar;
public TrackBarMenuItem():base(new TrackBar())
{
this.trackBar = this.Control as TrackBar;
}
// Add properties, events etc. you want to expose...
}
Thanks to the ToolStripItemDesignerAvailability
attribute, you can even see the item in the Forms Designer, as shown in the image below:

This solution comes from this MSDN example
