I created a "Asp.net Web Application" in Visual Studios 2008 that just generates a simple invoice using Microsoft Reports.
I used the Dataset designer to design a Dataset for the Invoice Info, and another Dataset to fetch the company information.
The Report is local (.rldc) using ReportViewer 2008 (9.0.0.0)
The dataset does not have a tableadapter, it just has the datatable.
The actual data is filled manually and assigned to the report viewer during runtime.
The project runs fine without any errors in debugging.
But when I copied the files over to the webserver it gave me the
"Compiler Error Message: BC30002: Type 'InvoiceFinalizedPrinting' is not defined."
That is the dataset I created.
I double checked, the dataset is in the App_data sub folder from where the Print.aspx page is located.
It should work, but I have no idea why it doesn't.
