The Radius property allows you to get or set a value that represents the distance in pixels from the center to the edge of the circular region defined by this CircleHotSpot object. To completely define a CircleHotSpot object, you must specify a value for the Radius property as well as the X and Y properties.
The following code example demonstrates how to create an ImageMap control that contains two CircleHotSpot objects. One is created declaratively; its X, Y, and Radius properties are likewise set declaratively. The other is created programmatically and its X, Y, and Radius properties are set programmatically. 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.
