Introduction to GeneXus for GeneXus for mobile Course
Interactive screens: Web Panel object
We build a screen similar to the one implemented by the Work With pattern of
attractions: with a grid with attributes sorted by certain criteria, with filters on data, entered by the user, and actions on the grid data, among other things.
We will implement a web panel with a grid with attributes and variables, and see the system’s Start, Refresh and Load events, as well as user events, particularly the Click associated with an attribute or variable in the grid. We will call the Attraction transaction modified by the pattern, in Update mode. We will see the system’s &Mode variable in transactions, and the values it takes. We will see that the attributes correspond to the output and the variables to the input. We will see how to make a variable Readonly.
