Version: GeneXus 18

GeneXus Core course

Rules definition

There is a place in each transaction to specify rules to be triggered when the user interacts with the screen (to insert, modify or delete information).

Total length of videos: 8h 30m

We see how to ensure that, in the Customer transaction:

no record is mace of a customer with empty name, empty surname, or a date in the system later than today (Error rule) a warning message is shown when the phone remains empty (Msg rule) the day’s data is automatically assigned to a Date attribute (Default rule) the edition of an attribute is disabled (Noaccept rule) We also see how to condition the triggering of a rule.

Specifically, in relation to the operation that is to be carried out: Insert, Update or Delete.

We show what variables are and what they are used for, and how we define variables in objects, as well as their main difference compared to attributes.


Expand the knowledge learned in the course
Upgrade your app from prototype to production


Through the development of an application, we will teach you the basics of GeneXus that will allow you to understand its logic and quickly build any type of application, now or in the future.

The application developed will be a Web application but most of what has been seen will be valid for Web Angular development or for native mobile applications. The equivalences will be indicated in the video "Introduction to the Course".

Basic programming and database skills. If you do not have them, we recommend that you study this material prior to the start of the course.

Suggested methodology for this course:
Alternate the theory with practice exercises you can download from the “Materials” section. 
Watch every video and in parallel do the practice exercises corresponding to those topics, until you have completed all the videos of the course. 

Approximate duration: 
Theory/Practice: 45 hours (not including the optional "bonus videos" that appear at the end of the course)
