This article, authored by Fredrik Engseth, delves into the use of Power FX snippets to customize Commands in Model-Driven Apps. Power FX, a new methodology for building logic and visibility rules, is said to replace JavaScript and RibbonWorkbench.

The blog presents a useful 'cheat sheet' of examples featuring commonly used Power FX snippets. The snippets have been outlined based on Engseth's personal experience, intending to aid other developers. Notably, the list of examples does not hail itself as exhaustive.

Engseth has included a Table of Contents to efficiently navigate through the blog, which is categorized under various sub-headings including Prerequisite, Notifications in a Model-Driven App, Visibility Formulas in a Model-Driven App, Patch Function, and Navigation.

Power FX and App Alerts

Engseth exemplifies several types of notifications like Dialogs and Banners that could be well-incorporated into a developer app. These alerts assist in maintaining transparency about ongoing tasks in the system, ensuring users stay updated about each process.

He further points out creating an Abort Dialog and Notification Message for an event, enabling system-initiated communications with the user. In addition to this, Engseth also highlights an example of a successful dialog and notification message scenario.

Power FX and Commands Visibility

The author provides model visibility rules, which govern the display of Commands in developer apps. He explains how these rules can show or hide Commands based on specific conditions. He provides models for hiding a command during record creation and commands visibility based on record data.

Power FX Patch Function

This discusses the Patch function which enables updating and record creation with PowerFX. It showcases how a task related to the current record can be created. Additionally, the function provides insight into record updates - for a single field on a record, multiple selected records, and updates based on certain criteria.

Navigating Model-Driven Apps

Engseth provides examples of using Power FX to navigate to the default and specified views of the table, along with opening selected records in new tabs. For Norwegian users, it presents an example of how to open single or multiple records in Brønnøysundregisteret from a list view.


To sum up, utilizing Power FX for Commands in developer apps is beneficial in terms of functionality and convenience.
