Configure CoordinateConversion Widget to Show Only XY Format as Lat, Lon (ArcGIS JS API v4.32)

Hi everyone,

I'm working on an Angular app using ArcGIS JavaScript API v4.32, and I need help customizing the CoordinateConversion widget.

I want to achieve two things:

Keep only the "XY" format option (i.e., hide MGRS, UTM, etc.).
Display it in Lat, Lon order (Latitude first, then Longitude)

I’ve tried this:

const latLonFormat = new CoordinateFormat({ name: "Lat Lon", currentPattern: "YX", defaultPattern: "YX" }); const coordinateConversion = new CoordinateConversion({ view: this.view, formats: [latLonFormat], multipleConversions: false, visibleElements: { settingsButton: false, editButton: false, expandButton: true, captureButton: true } });

But the widget still displays Longitude, Latitude (i.e., X, Y), regardless of what I set in currentPattern.

Hi @alabanu, thanks for posting your question here. You can do this, but you need to handle both the conversion and the reverse-conversion functions. Here is a sample app that you can follow:
