title: Display exception message through javascript alert in asp.net
body: <p>I am trying to show exception message through javascript alert box.</p>
  
  <p>Here is the sample code.</p>
  
  <pre><code>public static void HandleException(Page page, Exception ex)
  {
      string message = ex.Message.ToString();
      ScriptManager.RegisterClientScriptBlock(page, page.GetType(), "", "alert('"+message+"');", true);
  
  }
  </code></pre>
  
  <p>It runs if i give literal values for the string variable. 
  e.g.</p>
  
  <pre><code>string message = "Hello World";
  </code></pre>
  
  <p>But it fails if I give message = ex.Message;</p>
  
  <p>Any Idea?</p>
