What is Microsoft Power Fx?

Greg Lindhorst, Principal Program Manager, 2021年3月2日

Microsoft Power Fx is the low code language for expressing logic across the Microsoft Power Platform.  It is the same language that is at the heart of Microsoft Power Apps canvas apps today and is inspired by Microsoft Excel.   It enables the full spectrum of development from no code to pro code with no cliffs in between, enabling diverse teams to work together and saving everyone time and money.  We are very excited to bring it to more of the Power Platform and to share it with everyone as open source.  Only through a strong user community can a language grow and flourish.

Enhanced component properties

Greg Lindhorst, Principal Program Manager, 2021年2月18日

Enjoy two new experimental features for formula based components. Behavior properties enable a component to fire a custom event into its container, such as OnChange. Property parameters enable the passing of arguments for a property evaluation, providing our first steps toward formula based user defined functions.

Source code files for Canvas apps

Greg Lindhorst, Principal Program Manager, 2021年1月14日

Imagine using GitHub and Visual Studio Code with the text formulas of a Canvas app.  Teams can collaborate on apps: they can work on private branches, diff changes, create pull requests for review, and merge into master. We are very pleased to announce the experimental release of a tool that enables these modern miracles.  It is but the first step as we make application lifecycle management easier for formulas and Canvas apps.

Formulas: ThisRecord, As, and Sequence

Greg Lindhorst, Principal Program Manager, 2020年7月20日

You can now refer to the whole record in ForAll and other record scope functions with ThisRecord.  You can even name that record with the As operator, allowing you to clarify formulas and work with all the records in nested ForAll and Gallery controls.  And finally, we’ve added Excel’s Sequence function to generate a table containing a sequence of numbers, perfect for iterating a specific number of times with ForAll.

Announcing Column Comparison through FetchXML, SDK, and OData

Nathan Helgren, 2020年7月14日

We are happy to announce the availability of column comparisons. This has been a common ask from our MVPs and ISVs for a while now and it’s exciting to provide this functionality.

Authoring formulas with dynamic schema in Power Apps

Lance Delano, Principal Program Manager, 2020年6月23日

It is now possible to use dynamic schema as part of Power Apps formulas.

Formulas: Notify timeout and Exit sign out

Greg Lindhorst, Principal Program Manager, 2020年5月22日

You can now set the timeout for the Notify function, controlling how long the banner appears, from 1 millisecond to infinity. And you can now sign out the current user with the Exit function, important in situations were devices are shared such as health care.

Formulas: Launch to self and Self operator

Greg Lindhorst, Principal Program Manager, 2020年5月21日

You can now replace a canvas app with another app or a web page in the same browser tab. In addition, a control can refer to itself in formulas.

Introducing Monitor to debug apps and improve performance

Greg Lindhorst, Principal Program Manager, 2019年10月18日

You now have a new tool to better understand, debug, and improve your apps.  Similar to a network trace, Monitor provides a running list of all the activity within your app.   You can examine what data requests are made from your app, how long they took, how much data was returned, and which resulted in an error.
