How to Add/Draw Polylines in the .NET MAUI Maps (SfMaps)?
In the Syncfusion® .NET MAUI Maps control, you can add or draw polylines in the SfMaps through the following steps:
Step 1: Add the SfMaps control to your layout. Initialize the MapShapeLayer, as shown in the following code sample.
XAML:
<map:SfMaps> <map:SfMaps.Layer> <map:MapShapeLayer> </map:MapShapeLayer> </map:SfMaps.Layer> </map:SfMaps>
Step 2: Set the ShapesSource property for geographical rendering and define the ShapeStroke to DarkGray to separate state borders:
XAML:
<map:MapShapeLayer ShapesSource="https://cdn.syncfusion.com/maps/map-data/india.json" ShapeStroke="DarkGray"> </map:MapShapeLayer>
The ShapesSource can be a GeoJSON or shapefile from a local file, URL, Stream, or Resource.
Step 3: Add the MapPolylineLayer to the MapShapeLayer’s Sublayers, and set the AnimationDuration and AnimationEasing properties, as shown in the following code sample.
XAML:
<map:MapShapeLayer.Sublayers>
<map:MapPolylineLayer AnimationDuration="3000"
AnimationEasing="{x:Static Easing.SinInOut}">
</map:MapPolylineLayer>
</map:MapShapeLayer.Sublayers>
Step 4: Add the Polyline Points of type MapLatLng to connect multiple location coordinates, as shown in the following code sample.
XAML:
<map:MapPolylineLayer.Polylines> <map:MapPolyline> <map:MapPolyline.Points> <map:MapLatLng Latitude="13.0827" Longitude="80.2707" /> <map:MapLatLng Latitude="13.1746" Longitude="79.6117" /> <map:MapLatLng Latitude="13.6373" Longitude="79.5037" /> <map:MapLatLng Latitude="14.4673" Longitude="78.8242" /> <map:MapLatLng Latitude="14.9091" Longitude="78.0092" /> <map:MapLatLng Latitude="16.2160" Longitude="77.3566" /> <map:MapLatLng Latitude="17.1557" Longitude="76.8697" /> <map:MapLatLng Latitude="18.0975" Longitude="75.4249" /> <map:MapLatLng Latitude="18.5204" Longitude="73.8567" /> <map:MapLatLng Latitude="19.0760" Longitude="72.8777" /> </map:MapPolyline.Points> </map:MapPolyline> </map:MapPolylineLayer.Polylines>
