    Me.ReportViewer1.RefreshReport()

Answer 4

if you add another table to the xsd form after adding the report to the report viewer you might get this error.

1. delete to report viewer and add it again
2. set the report to the report viewer

3. now go to the Load event of the form (that includes the report viewer and add the Fill for new dataset.

   private void rptForm_Load(object sender, EventArgs e) {
     this.vwrpt_TableAdapter1.Fill(this.DataSet1.vwDataset);
   }
   

Answer 5

I just had this issue with VS 16.4.6 and the latest report designer extension 15.3.1.

For me it was caused by giving the data set a slightly different name to the set I'd chosen from the drop down. It took me ages to figure out what was wrong. A hunch suggested it might be an issue. So I renamed the data set to match the source data entity and the error went away.

But why offer the user the chance to call the data set something else and then not test that this actually works?

The report viewer extension is still really poor quality.

Answer 6

"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.
