Output page not rendered correctly
<p>I created a page with some controls on it.  When I put "&lt;% label.Text = "changed";%>" after the definition of Label, Label's text value is not rendered after the page is executed. Why?</p>

<pre><code>&lt;div&gt;
   &lt;tagprefix:MD ID="CC"  runat="server" /&gt;
        &lt;asp:TextBox runat="server"  ID="TextBox1"/&gt;
        &lt;asp:Button Text="button" ID="Button"  runat="server" onclick="Button_Click" /&gt;
        &lt;%= "Hello..." %&gt;

        &lt;% label.Text = "changed"; %&gt;                          //working fine
        &lt;asp:Label ID="label" Text="text" runat="server" /&gt;
        &lt;% label.Text = "changed"; %&gt;               // do not work
&lt;/div&gt;
</code></pre>
