Inherit class from page, usercontrol, and masterpage
<p>I have <code>Page</code>, <code>MasterPage</code> and <code>UserControl</code> in my project.</p>

<p>So I create <code>basepage</code> class and share some logic, then inherit from System.Web.UI.Page. My problem is I want use single basePage for any type of UI content.</p>
