title: C# ASP.NET Korzh Query Builder Custom Value Editor
body: <p>I would like to find out from someone if they have worked with <a href="http://devtools.korzh.com/" rel="nofollow">Korzh Query Builder</a> before.</p>
  
  <p>If so, have you tried implementing a Custom Value Editor, and if so, how did you do this, and if possible do you have any links/documentation.</p>
  
  <p>The provided exaples/documentation is a bit shoddy.</p>
  
  <p>I have spent some time trying to figure this out, as the List examples are very slow once the number of items breach the 1000+ mark.</p>
  
  <p>Any help/articles/links in this regrds will be greatly appreciated.</p>
