The MapAreasCollection class represents a collection of MapArea objects, which in turn represent map areas of a client-side image map, such as HTML <AREA> tags.
This class is used in two ways:
As the MapAreas property of the root Chart object, which is used for custom map areas. These custom map areas have a user-defined shape and coordinates, and can be added at either design time or at run time using the overloaded M:System.Web.UI.DataVisualization.MapAreasCollection.Add or M:System.Web.UI.DataVisualization.MapAreasCollection.Insert methods.
In the CustomizeMapAreas event, as the MapAreaItems property of the CustomizeMapAreasEventArgs parameter. This MapAreaItems property stores T[:System.Web.UI.DataVisualization.Charting.MapArea] objects that have automatically been created for a chart object (map areas are automatically created when an applicable chart element, such as a data point, series, legend item or stripline object, has a non-empty ToolTip, Url or MapAreaAttributes property). In this case the dimensions and location of a map area are determined by the chart element. The MapAreaItems property enables you to delete or modify these automatically generated map areas, and can also be used to add custom map areas.
A client-side image map will only be created at run time if the IsMapEnabled property of the root Chart object is true. This is the default.
Important To create an image map using the previously described MapArea objects, the RenderType property of the Chart object must be set to ImageTag. It is possible to create an image map when using binary streaming, but a special technique must be used.
