Features

• always server side checked attributes required, disabled and readonly
• all HTML5 specific and global atributes (by Mozilla Development Network Docs)
• every field has it's build-in specific validator described above
• every build-in validator adds form error (when necessary) into session and than all errors are displayed/rendered and cleared from session on error page, where user is redirected after submit
• any field is possible to render naturally or with custom template for specific field class/instance
• very extensible field classes - every field has public template methods:
  • SetForm() - called immediatelly after field instance is added into form instance
  • PreDispatch() - called immediatelly before any field instance rendering type
  • Render() - called on every instance in form instance rendering process
    • submethods: RenderNaturally(), RenderTemplate(), RenderControl(), RenderLabel() ...
  • Submit() - called on every instance when form is submitted
