DevX has just published Part 1 of my article Building Report-enabled Applications with the Windows Forms ReportViewer. Part 2 (ASP.NET ReportViewer) should be out by the end of February.
Reporting is an integral part of every complete application. The Report Viewer controls greatly reduce the development effort required to report-enable .NET applications. Part one of this two-part article shows you how you can leverage the Windows Forms ReportViewer to integrate your Windows Forms .NET applications with Reporting Services 2005.
