At googlemapcontrol.com you can find information about Google Maps Control and look at the code samples to get familiar with the control.
We created the GoogleMap Control Suite of map controls, extenders and components add interactive, customized maps and GIS features to the websites and applications you build with the Microsoft .NET and Xamarin Frameworks. As a software developer, you can use GMC Map Suite’s powerful map API to add geospatial functionality to your projects, including geocoding, spatial analysis, optimized routing, geoprocessing, and much more using C# and VB.NET.
Some of the features included in the Google Map JS API version 3 Wrapper
Add any markers of your choice and style
Geocoding is the process of converting addresses (like ”1600 Amphitheatre Parkway, Mountain View, CA”) into geographic coordinates (like latitude 37.423021 and longitude -122.083739), which you can use to place markers on a map, or position the map.Reverse geocoding is the process of converting geographic coordinates into a human-readable address. The Google Maps Geocoding API’s reverse geocoding service also lets you find the address for a given place ID.
Import data from either a local or remote source, and display it on your map
Handling Map Events
Handle serverside-events using the Google Maps .NET Control. Advanced serverside event handling using callbacks
Add lines, Poylgon, Circles
Add what youy want
The DrawingManager class provides a graphical interface for users to draw polygons, rectangles, polylines, circles, and markers on the map.
Most developers can simply use the basic map types noted below. However, you can also define your own map tiles using custom map types or modify the presentation of existing map types using Styled Maps. When providing custom map types, you will need to understand how to modify the map’s Map Type Registry.
Add infoWindow’s to multiple markers on a Google Map. Fill it with innerHTML content like images, database content and ASP-net buttons
Add custom labels
Adding Overlays to Maps
The whole point of displaying a map on your page is to present some information. Google’s Map API allows you to display two types of overlays: markers and polylines.
