Using patterns
On GeneXus objects defined in the KB such as transactions, we may apply some patterns that build other objectos on them to add functionalities, like those provided for by the pattern Work with the data of a trasaction.
Version: GeneXus 17
GeneXus Core course
The Work With for Web pattern is applied to Country and Attraction transactions. The consequences in execution are shown, through the objects that the pattern itself generates to implement attractive screens that allow the information of countries and attractions to be displayed on a grid. You can see how to customize what is generated: remove / add attributes to the grid, add filters and orders, how to enable or disable the standard actions on the data (insert, update, delete). The dynamism between transaction structure, pattern instance and generated objects is studied. See how to un-apply a pattern.

Presentation
Objective:
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.
Prerequisites:
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)
If you purchase the course, you will work on it within a study platform (LMS) and you will also have:
Exam:
It is a computer-based exam, with multiple choice and true/false questions and exercises.
When you pass the exam, you will receive an internationally valid “GeneXus Junior Analyst” certification and will be included in the list of GeneXus-Certified Technicians.
Here you can see the Exam Calendar.
