GeneXus 9.0 Overview

With GeneXus 9.0 you are able to build more with less, translate your applications easily and have more connectivity, while making your applications available on more platforms and providing better user experience!
GeneXus 9.0 lets you:

Main Features

Did you ever imagine you could generate the whole application just by designing transactions (i.e. the data model)? Use the predefined patterns or define your own, and let the Patterns build your application. More information...

Web Development
more features related to web development than ever have been added to this version.


  • Web client side validation: In this version, GeneXus generates client-side code (Javascript) in web applications using Ajax architecture. Many rules are triggered in the browser avoiding a roundtrip to the server! (And you don't need to know jscript...) For more information see "Improved User Experience for generated information" section below.
  • Master Pages: This feature allows you to define the general layout just once and not in every page. Main benefits are consistent look & feel, less coding, better performance. Just change the Master Web Panel and the whole application changes! More Information...
  • Blobs in Web Forms: Blob fields can now easily be displayed in the browser and uploaded to the Database! Just insert a BLOB attribute in the form and see how it works! More Information...



Improved User Experience for generated applications
A set of new features related to user experience have been added. In web: using Ajax architecture!
And all this without need of knowledge about how to code jscript, xml, etc.



  • Improved Client-side validation in web: It triggers formulas and gets inferred attributes after validating Foreign keys; user experience like a win application! Just generate again your KB and enjoy! More Information...
  • Suggest (intellitips) in win and web: Setting a property you allow the user this: he writes just some characters and the application gives him automatically the rest and/or suggests him the possible values!! More Information...
  • Input type "Values" or "Descriptions" in win and web: Avoid prompting for the possible values of the Foreign Keys! In the Invoice: enter the Client Name instead of the Client Id! Combine this feature with Suggest and you get incredible user experience. More Information
  • Dynamic combo boxes with filters in win and web: You can set loading conditions of a dynamic combo box. For example, the application filters in run time the Cities, showing just the ones from the selected Country. When you change the Country, the Cities are reloaded appropriately.More Information...
  • New charts: Get charts with a renewed Look & Feel and with more power and less requirements More Information...
