title: Meaning of the various symbols in .aspx page of asp.net
body: <p>I have come across different symbols in .aspx page of asp.net</p>
  
  <pre><code>&lt;%#eval(expr) %&gt; 
  &lt;%#bind(expr) %&gt;
  &lt;% %&gt;  - for specifying the c# code in aspx page
  &lt;%$ %&gt; - for specifying the SQL connection string in &lt;asp:SqlDataSource&gt;
  </code></pre>
  
  <p>Is there any underlying logic behind these symbols or is it just syntax which we have to remember blindly? What does &lt;% %> mean in general?</p>
