Microsoft’s Model-Driven commanding

Microsoft has announced that the makers can create their own commands using Power Fx and the familiar Excel formula bar.  This will definitely result in the lower the bar to expressing logic for developers as they no longer need to learn and debug asynchronous JavaScript code. 

Command Designer in Model-Driven app

In the below given animation, the new command fx designer is being used to create a new command which will add a new related Task record to the current Account record.  The designer includes the Power Fx formula bar accompanied with IntelliSense and error reporting.  As with buttons in canvas apps, the OnSelect formula is being edited to include a Patch function call to create the record.

Microsoft has announced that the Power Fx Command bar will get rolled out after June 2021 (Region specific rollout).

Benefits of Power Fx command

1. Low Code / No Code approach for customizing the Model-Drive app’s command bar.
2. Elimination of 3rd party tools for customizing the command bar.
3. Utilization for FX formulas which are more likely similar to the excel driven formulas.

As a conclusion, the new Power Fx command feature will speed up the product development and give a low code approach for customizing the ribbon buttons in the Model-Driven apps.
