CircleHotSpot Constructor

Initializes a new instance of the CircleHotSpot class.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public CircleHotSpot()

Use this constructor to initialize a new instance of the CircleHotSpot class.

The following code example demonstrates how to programmatically create two CircleHotSpot objects, set their properties, and add them to the ImageMap control's HotSpotCollection. For this example to work correctly, you must supply your own image for the ImageUrl property and update the path to the image appropriately so that the application can locate it.
