HotSpotMode enum has following values Inactive NotSet Navigate Postback You can set HotSpotMode either on ImageMap control or individual HotSpot control for the ImageMap. If you specify it on ImageMap only, all the HotSpot controls interhit the behavior. All HotSpot controls must be set to NotSet to inherit the behaviour. If you specify NotSet on ImageMap and HotSpot control, the default behaviour is Naviagate. If you specify NotSet only on HotSpot, it works out the behaviour based on the setting on ImageMap. The setting on HotSpot takes precendence over the ImageMap. The settings take precendence in the order they are specified. Hence you should specify inactive map before you specify active map to create complex mapping.
