-<!-- Class --> 
-Serves as the base class for the overlay that generates and manages markers. 
-=== Remarks === 
-The &​lt;​strong&​gt;​MarkerOverlay&​lt;/​strong&​gt;​ class is the base class for any overlay that deals with markers. A &​lt;​strong&​gt;​MarkerOverlay&​lt;/​strong&​gt;​ object corresponds to a &​lt;​strong&​gt;​div&​lt;/​strong&​gt;​ that holds a group of marker images at the client side. The MarkerOverlay class has a &​lt;​strong&​gt;​GetMarkers&​lt;/​strong&​gt;​ method that generates a collection of markers. These markers will be serialized to a JSON string and sent to the client to create the client marker objects. If you want to create your own MarkerOverlay,​ inherit from this class and override the &​lt;​strong&​gt;​GetMarkerCore&​lt;/​strong&​gt;​ method.

-==== OnClick(MarkerOverlayClickEventArgs) ==== 
-Raises the Click event of the MarkerOverlay object. 
-=== Remarks === 
-The &​lt;​strong&​gt;​OnClick&​lt;/​strong&​gt;​ method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.&​lt;​strong&​gt;​Notes to Inheritors:&​lt;/​strong&​gt;​ When overriding &​lt;​strong&​gt;​OnClick&​lt;/​strong&​gt;​ in a derived class, be sure to call the base class'​s &​lt;​strong&​gt;​OnClick&​lt;/​strong&​gt;​ method so that registered delegates receive the event.
