Loading UserControls in Panel in C#

I'm new to C# and VS.NET and was having an issue I was hoping someone could help me with.  I have a main form that has some standard information I would always like to display on my application (like a header for a webpage but in this case an application).  I then have a panel on my main form called targetPanel which I was wanting to load UserControls I created into.  Basically the application will load one UserControl on startup and then when clicking a button (located inside that user control) it should be able to load another user control inside this targetPanel. Below is some code I was using to try and do this.

public void ShowControl(UserControl controlName){
   targetPanel.Controls.Clear(); // Remove any current controls in the panel
   targetPanel.Controls.Add(controlName); // Put the special control in the host panel
   controlName.Dock = DockStyle.Fill; // Make the control fill the host panel
}

The problem of course is that every userControl is its own class in C# and already has inheritance with the UserControl class built in with .NET.  So how do I have one user control communicate with the MainForm so that it can alter the panel I have on that form called targetPanel so it can load another UserControl based on what was selected?

I would greatly appreciate some assistance as this has been bugging me.  Thank you.
