title: Problem with centralized form validation framework for an ASP.NET(C#) 3.5 web app using ASP.NET validation controls and AJAX?
body: <p>I need to implement a centralized form validation framework for my ASP.NET(C#) 3.5 website. </p>
  
  <p>And for this I have tried the following solutions-</p>
  
  <ol>
  <li><a href="http://blogs.msdn.com/b/mattgi/archive/2007/01/23/asp-net-ajax-validators.aspx" rel="nofollow noreferrer">http://blogs.msdn.com/b/mattgi/archive/2007/01/23/asp-net-ajax-validators.aspx</a>  </li>
  <li><a href="http://validationframework.codeplex.com/" rel="nofollow noreferrer">http://validationframework.codeplex.com/</a></li>
  </ol>
  
  <p>I have added the .dll file in my project's BIN folder and for Matt Gibb's solution I have also added the tagMapping code to web.config file. But for both of the solution, when I ran the project I noticed it doesn't have any effect on the validation controls.</p>
  
  <p>So none of the above mentioned solution are working for me.</p>
  
  <p>Can anyone figured out what I'm doing wrong?</p>
  
  <p>Or can anyone let me know any other reliable working solution?</p>
