Power Fx: Column names escape double quotes

Headshot of article author Greg Lindhorst

, Principal PM Architect, Τετάρτη, 10 Απριλίου 2024

We are making a small syntax change to how column names are specified in AddColumns, DropColumns, ShowColumns, RenameColumns, Search, GroupBy, Ungroup, and DataSourceInfo functions.  Today they need to be wrapped in double quotes as a text string, but tomorrow they will not.  We will automatically update the syntax in existing apps to reflect the new syntax.  The change makes these functions consistent with other uses of column names, easier to use by no longer requiring logical names, and consistent with other Power Fx 1.0 hosts such as Copilot Studio, Power Automate Desktop, and Cards that have been using this new syntax for the last year.

Headshot of article author Greg Lindhorst

, Principal PM Architect, Τετάρτη, 20 Οκτωβρίου 2021

There is a new declarative way to control the first screen shown in a Canvas app: App.StartScreen. It is our first step in providing declarative alternatives for all the things that are done in App.OnStart today. App.OnStart is the source of many app load performance issues as it’s imperative nature prevents many optimizations. Not only that, declarative alternatives are easier to use and less error prone.
