Answer 1

"ProductsDataSet" is the name of the DataSource you are giving it. Your Error is saying "A data source instance has not been supplied for the data source“Product_Detail” in Microsoft reporting service"

I'm assuming you're assigning it the wrong name.

Try,

ReportDataSource rds = new ReportDataSource("Product_Detail", ds.Tables[0]);

If you do have a datasource in the report called "ProductsDataSet" then you probably have 2, in which you'd wanna delete the one you aren't using or assign it a datasource as well.
