Examples

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.
