GeneXus 9.0 Upgrade Course

Demo: Introduction to Web Client Side Validation

Suppose we have the well-known application about Countries, Cities, Customers, Products and Invoices.

As we already know, if the application is generated in Java or .Net Win, the end user could have a high interactiveness level, because of the Client Side Validation property, that enables rules and formulas, as well as integrity controls, to trigger meanwhile the user is moving along the fields of the form.

And, what happens with the same application but generated in Java or .Net Web?

In the following video, we'll see a GeneXus 9.0 .Net Web Prototype, with the Country, City, Customer, Product and Invoice transactions. There are other objects too, that were generated using the Patterns Tool that we will see few sections later. Now we'll put the focus on the transactions and its rules, as well as the integrity controls, and in the moment where they are triggered, and we'll leave the other aspects of the application for later.

As we saw in the demo, a text box control (client side error viewer) will now be displayed on the control that triggers a message or error when leaving it.

They have two classes associated with Themes: ErrorMessages and WarningMessages that belong to the new Messages class. You can modify their configuration, such as modifying the background colour of the box, as you can see in the following demo... (WCSVErrorMessages.html)
