I happened to download ActiveAnalysis from the grapecity web site and just discovered Componentsource.com. Very pleasantly surprised by the promise this components holds for developing OLAP and data visualization apps, tonnes of features available with minimal coding. I like the fact that I can use just one component to develop on windows forms, silverlight and asp.net and impress my customers with the seamless switching between text and graphics views regardless of whether we build a web app or a windows app. Very cool product! The stand-alone Viewer with source code, solution galleries and good documentation were a bonus!
