How to Add Markers at the Tapped Locations in the .NET MAUI Maps (SfMaps)?
In the Syncfusion® .NET MAUI Maps control, you can add markers at tapped locations in the SfMaps through the following steps:
Step 1: Add the SfMaps control to your layout. Initialize the MapTileLayer to render the tiles returned from the Web Map Tile Services and set the URL to the UrlTemplate property, as shown in the following code sample.
XAML:
<map:SfMaps x:Name="map">
<map:SfMaps.Layer>
<map:MapTileLayer x:Name="tileLayer"
UrlTemplate="https://tile.openstreetmap.org/{z}/{x}/{y}.png">
</map:MapTileLayer>
</map:SfMaps.Layer>
</map:SfMaps>
Step 2: Add MapMarker to the MapTileLayer’s MapMarkerCollection, as shown in the following code sample.
XAML:
<map:MapTileLayer.Markers> <map:MapMarkerCollection> <map:MapMarker x:Name="marker" Latitude="-14.235004" Longitude="-51.92528" /> </map:MapMarkerCollection> </map:MapTileLayer.Markers>
Step 3: In the MapTileLayer.Tapped event, obtain the touch position and set the corresponding Latitude and Longitude to the marker’s Latitude and Longitude properties, as shown in the following code sample.
C#:
public class MapsBehavior : Behavior<ContentPage>
{
private MapTileLayer tileLayer;
private MapMarker marker;
protected override void OnAttachedTo(ContentPage bindable)
{
base.OnAttachedTo(bindable);
this.tileLayer = bindable.FindByName<MapTileLayer>("tileLayer");
this.tileLayer.Tapped += TileLayer_Tapped;
this.marker = bindable.FindByName<MapMarker>("marker");
}
private void TileLayer_Tapped(object sender, Syncfusion.Maui.Maps.TappedEventArgs e)
{
var location = tileLayer.GetLatLngFromPoint(e.Position);
marker.Latitude = location.Latitude;
marker.Longitude = location.Longitude;
}
protected override void OnDetachingFrom(ContentPage bindable)
{
base.OnDetachingFrom(bindable);
if (this.tileLayer != null)
{
this.tileLayer.Tapped -= TileLayer_Tapped;
}
this.tileLayer = null;
this.marker = null;
}
}Download the complete sample on GitHub.
