"DHTMLX released version 3.0 of their JavaScript UI library. The main idea behind this release is to make web application development easier and more effective by introducing a Visual Designer tool and a global data store approach.
Visual Designer with Form Builder
DHTMLX Visual Designer allows developers to quickly build web interface structure without writing a line of code. You can easily create a web application prototype in a simple visual environment, download generated source code, and then add necessary enhancements. Built-in form builder greatly simplifies the creation of web forms.
Global Data Store
The new ability to use global data store allows for more effective data processing in applications built with the DHTMLX library. You can keep all application data in one place and then share it between UI components. When data is changed, all components connected to the data store update their records. Synchronization with the server side can also be done through a data store.Updated Form
The new version of the JavaScript dhtmlxForm component offers various ways to position form elements and to build web forms with complex structure. The updated version supports multi-column forms, field sets, and absolute positioning of form elements. It also introduces integration with the DHTMLX calendar, combo box, color picker, and simple text editor.
Other Features
Other new features of DHTMLX 3.0 include renewed dhtmlxCalendar with new modern look and message utility to notify the end user about application activities (client-server communication, etc).
