Greetings from Syncfusion.

Query 1: Events that could be picked up on when a marker is moved.
MarkerSelected event will be fired when selecting the marker. Please refer the following UG document for more information.
Query 2: Marker co-ordinates
We have implemented the “Get Latitude and Longitude coordinates of Markers based on point and vice versa” feature and included in our latest Beta version (17.10.32).
Please find the below details for more information about the feature.
SfMaps offers two utility methods to transform the pixel values to longitude and latitude values and vice-versa. This method is used for both ShapeFileLayer and ImageryLayer.
GeopointToViewPoint(double latitude, double longitude) - Converts the latitude and longitude values to screen point. Here, pass the parameters as latitude and longitude values, from that values we can get screen points x and y.
GetLatLonFromPoint(Point point) - Converts the screen point to longitude and latitude values. Here, pass the parameters as screen points x and y, from that points we can get longitude (Point.X) and latitude (Point.Y) values.
We have prepared the sample. Please find the sample from the following location.
Also, we have published our Volume1 Beta release and the feature was included in the new version. Please find below the Volume 1 2019 Beta Release v184.108.40.206 link.
