.rdlc Report - Cannot create a data reader for dataset 'DataSet1'

Question

I have created a .rdlc-Report under VS 2012 using the report wizard and added data source and dataset. When I try to render the report using the code below I get following error message: Cannot create a data reader for dataset 'DataSet1'. ``` bytes = localReport.Render("PDF", sdeviceinfo, out smimetype, out sencoding, out sfilenameextension, out streamids, out myWarnings); ```

Accepted Answer

I have same problem that "Cannot create a data reader for dataset 'zzz'"

The answer is `ReportDataSource(string xxx, DataTable yyy)`

You should use the right name. xxx should be zzz
