c# Custom Control Navigation
<p>I have a bunch of Custom Control Forms (i.e. login page, home page, etc.) that I want to be embedded within a "main form". Every time the user navigates to another page, only the content of the "main form" gets changed.</p>

<p>But the only way I can do this is to copy the contents of the Custom Controls and paste them into the "main form" - which is messy. Is there a standard way of doing this type of thing?</p>
