Gets a collection of HotSpot objects that represents the defined hot spot regions in an ImageMap control.

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

[PersistenceModeAttribute(PersistenceMode.InnerDefaultProperty)]
public HotSpotCollection HotSpots { get; }

Property Value

Type: System.Web.UI.WebControls.HotSpotCollection
A HotSpotCollection object that represents the defined hot spot regions in an ImageMap control.

Use the HotSpots property to programmatically manage the hot spot regions in an ImageMap control. You can use the HotSpots property to add, insert, remove, and retrieve HotSpot objects. For more information, see HotSpotCollection.

The following code example demonstrates how to programmatically create an ImageMap control and add two CircleHotSpot objects to it. The HotSpots property is used to access the HotSpotCollection for the ImageMap control and add the CircleHotSpot objects to it. 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.
