The maptip sample at this location http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#MapTipWidget provides a popup containing attribute data when the state is clicked. This seems to be a built in feature of the maptip control since I can find no code to create it. Is there a way to surpress this action? I am handling the mouse click and attribute data differently and do not want this popup to occur. Thanks
