I have Visual Studio 2008, with the Business Intelligence Toolset. I want to build a WinForm application for my group that will contain a ReportViewer object. ReportViewer will only accept Reports from an RDLC file with the 2005 schema, not the 2008 schema. I also want the users to be able to build and view their Reports on the fly using the tool, without Visual Studio. It is possible to do this by manually editing the XML file, but nothing beats having a GUI. I have found that I can include the Microsoft.ReportDesigner.LayoutEditor control in my application (from C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\PrivateAssemblies), which allows me to create and edit RDL 2008 files on the fly, but I cannot view them with the ReportViewer. I do not see this as an issue, because our company has a site license, and the program will not be externally distributed. Where can I find the DLL that contains the ReportDesigner to create RDLC 2005 files? Since I can right-click and Add a Report object in Visual Studio 2008, and it opens with the 2005 editor, I know it must be somewhere on the computer, but I could use help finding the Winform control.
