body: <p>I'm using <code>Page.ClientScript.RegisterStartupScript</code> for displaying alert messages. it works fine for the first message, however second message wont display. Though it passes through the code while debugging. </p>
  
  <p>Below is the code. Here only <em>FiveDot File uploaded successfully</em> message is displayed.  </p>
  
  <pre><code>Page.ClientScript.RegisterStartupScript(GetType(), "msgbox", "alert('FiveDot File uploaded successfully');", true);
  Page.ClientScript.RegisterStartupScript(GetType(), "msgbox", "alert('TwoDot File uploaded successfully');", true);
  </code></pre>
