Map Points in WPF Maps (SfMap)
18 Aug 202124 minutes to read
Points are one of the record type in shape file layer. Points are used to specify the specific point in the map. For example, used to specify the capital of countries. Points in the shape file is given as latitude and longitude coordinates in the shapes file. Those points should be converted as MapPoints.
Customizing the MapPoint
The default appearance of the MapPoint can be customized by using the MapPointTemplate property. The MapPointTemplate property is available in the ShapeFileLayer.
About MapPointTemplate Property
MapPointTemplate is a DataTemplate type, used to customize or override the default template of MapPoints.

MapPointPopup
MapPointPopup is a popup, displayed when the point is moved to MapPoint. It shows additional information from the object bounded with the MapPoint. You can get the object from dbf file.
MapPointPopupTemplate
MapPointPopupTemplate is a DataTemplate, used to expose the template for the MapPoint.
