Reinstate ArcGIS.Desktop.Mapping.LayerPosition enum

[StefanDieters1]

In the transition from ArcGIS Pro 2.9 to Pro 3 the ArcGIS.Desktop.Mapping.LayerPosition was removed i.e.

see https://pro.arcgis.com/en/pro-app/3.0/sdk/api-reference/topic15120.html

https://pro.arcgis.com/en/pro-app/3.0/sdk/api-reference/topic15120.html#i-heading--detailed-list-of-...

look in API Changes Detailed List of Changes ArcGIS-Core 15th instance of 29 for LayerPosition.

The LayerPosition.AutoArrange option was very handy for adding external basemaps to a map. It would group basemaps together at the bottom of the Table Of Contents.

As in this useage:

layer = await QueuedTask.Run(() => LayerFactory.Instance.CreateLayer(uri, mapView.Map, LayerPosition.AddToTop, ShowName));

Alternative create an equivalent method or enum with the same functionality as the AutoArrage option.

@StefanDieters1 

It got moved to MapMemberCreationParams class. Please use the MapMemberPosition property of this class for this.

Please let me know if it doesn't work for you.

Thanks

Thanks @TanuHoque

that was the clue I need to convert my code across.

For anybody else that needs help here is a code snippet:

                        // Create the parameters
                        // note many more parameters are possible
                        // Use this pattern to create Feature layers, service layers ...
                        var parmeters = new LayerCreationParams(uri)
                        {
                            Name = ShowName,
                            MapMemberPosition = MapMemberPosition.AutoArrange,
                            IsVisible= true,                            
                        };
                        
                        // Layers such as the world toppgraphic and basemaps added via Layer > Basmap > select from gallery are not feature layers.
                        layer = await QueuedTask.Run(() => LayerFactory.Instance.CreateLayer<Layer>(parmeters, mapView.Map));

uri is the Uri(Path to the service providing the basemap) e.g. https://services.thelist.tas.gov.au/arcgis/rest/services/Basemaps/Topographic/MapServer

ShowName is a string describing the layer.
