    Remarks

    If following behavior is to be expected for the different possible values of this property:

    Never - an image map is never generated.

    Auto - an image map is automatically generated for all built-in async commands (like "refresh" and "autoRefresh") and is sent to the client, but only if there are elements that will produce image map areas.

    Manual - no image map is automatically generated; a manually added image map will be sent to the client only if there are elements that will produce image map areas. See AsyncQueryCommandResult for details how to add an image map manually to the result of an async command.

    Always - an image map is allways generated and sent to the client - for all commands and regardless of whether image map areas are generated or not.

    For all values, except Never, an image map is generated once every time the web control is initially rendered. This image map is available at the client immediatly after the Nevron JavaScript callback service has been initialized.

    To add areas to the image map, initialize the InteractivityStyle property of the Style object of visual elements with an instance of the Nevron.GraphicsCore.NInteractivityStyle class.
