Hi I'm having problem to add a Web Part in sharepoint service, I'm starting to use SharePoint so I don't know much about it. In this time I want to add a web part to presents a dashboard, so I'm using a ChartPart, I followed the manual but when I add the web part I receive Unable to add selected web parts ChartPart: A Web Part or Web Form Control on this Page cannot be displayed or imported. The type could not be found or it is not registered as safe I've read a lot of discussion but I think that they are advanced user and I don;t understand what they saying. Please HELP ME.
