I have a report that is used by a windows service and a form application. So, I want to put embed the report in a DLL file that can be used by both.
The problem is that
Just use the full namespace of the assembly, then folder names and then the name of the file:
rv.LocalReport.ReportEmbeddedResource =
"My.Assembly.Namespace.Folder1.Folder2.MyReport.rdlc";
Then make sure the report file is set as an embedded resource using the properties pane.
Probably the best thing to do would be to get a stream to the RDLC resource from the other assembly, then pass that to the "LoadReportDefinition" method of the Report Viewer control.
Details of how to get a stream from an embedded resource in a different assembly can be found here : Retrieving Resources with the ResourceManager Class
Additionally, you will need to refer to the embedded resource using it's full namespace path.
E.g. if you have an application with a default namespace of TheApp, and you keep a report called "MyReport.rdlc" in a folder called "Reports", the report reference call would be:-
rv.LocalReport.ReportEmbeddedResource = "TheApp.Reports.MyReport.rdlc";
Something like this should do it:
Assembly assembly = Assembly.LoadFrom("Reports.dll");
Stream stream = assembly.GetManifestResourceStream("Reports.MyReport.rdlc");
reportViewer.LocalReport.LoadReportDefinition(stream);
