VladV You could use built-in ASP.NET AJAX. Option 1 - use a web service (if you want the functionality to be reusable): create a web service (.asmx) with [ScriptService] attribute, add a to your page and add the web service to its Services collection, use JavaScript proxy generated by ScriptManager in yor page. Option 2 - use page methods (if you want the functionality on a single page without creating a
