Use SSRS. Either use asp.net pages for SSRS reports and end-user design, or use a silverlight report control like http://www.perpetuumsoft.com/Silverlight-Viewer-for-Reporting-Services.aspx?lang=en.

>>>We are in the process of rewriting our app using C# / Silverlight, and I'm researching .NET-based reporting engines to incorporate that support a Silverlight report preview control. Based on a cursory search, I came up with a short-list of products to look at more deeply:
>>>
>>>Xtra Reports (DevExpress)
>>>NetAdvantage Reporting (Infragistics)
>>>Report Sharp-Shooter (Perpetuum)
>>>ActiveReports (GrapeCity)
>>>Stimulsoft Reports
>>>Telerik Reporting

>>>I was wondering if anyone knew of any other products that might be worthwhile for me to examine, or any to stay away from.
