NullReferenceException when user control references usercontrol in parent user control
<p>I have a user control (uc1) which inherits from uc2. uc2 has a user control (uc3) declared in the markup. I am trying to access uc3 from uc1 but I get NullReferenceException. I thought due to inheritance uc3 would instantiate but looks like I am missing a step.</p>

<p><strong>Clarification:</strong></p>

<p>How does the child user control inherit the markup from the base class? The server controls in the base user control are null in the code behind of the base user control. Why?</p>
