Markers in .NET MAUI Maps (SfMaps)
7 Jun 202424 minutes to read
Markers can be used to denote the locations. It is possible to use the built-in symbols or display a custom control at a specific latitude and longitude on a map.
To learn more about the .NET MAUI Maps markers, you can check the following video.
Adding markers
Shape layer
You can show markers at any position on the map by providing latitude and longitude position to the MapMarker, which is from the Markers collection.

NOTE
- Refer to the
MapMarkerCollection, for collection ofMapMarker.
Appearance customization
You can customize the built-in markers appearance using the IconType, IconFill, IconStroke, IconStrokeThickness, IconWidth and IconHeight properties of the MapMarker.
-
Alignment - You can change the position of the marker from the given coordinate using the
HorizontalAlignmentandVerticalAlignmentproperties. The default value isMapAlignment.Center. The available alignment options areCenter,Start,End. -
Offset - You can adjust the marker position from the given coordinate using the
Offsetproperty. The default value of theOffsetproperty isOffset.zero.
NOTE
- The default value of the
IconTypeisMapIconType.circle.- The default value of the
IconStrokeThicknessis1.0.- The default value of the
IconFillisColor.FromRgb(138, 69, 175).- The default value of the
IconWidthandIconHeightis8.0.

Adding custom markers
You can show custom marker using the MarkerTemplate property of the MapShapeLayer which returns the template to customize markers.

Customizing data templates selector in markers
A data template selector also can be used to customize the appearance of each item with different templates based on specific constraints . You can choose a DataTemplate for each item at runtime based on the value of data-bound property using DataTemplateSelector in MarkerTooltipTemplate property.
