Private Sub ReportViewer1_Load(sender As Object, e As EventArgs) Handles ReportViewer1.Load

Try

If cn.State = ConnectionState.Closed Then
cn.Open()
End If

If cn.State <> ConnectionState.Open Then
MsgBox("Database Connectivity Error", MsgBoxStyle.Information)
Me.Close()

End If

ds.Reset()
str = "select * from TabSales"
cmd = New SqlCommand(str, cn)
da.SelectCommand = cmd
da.Fill(ds)
da.Dispose()
cmd.Dispose()
cn.Close()

Dim rds = New ReportDataSource("dsSales", ds.Tables(0))
MsgBox(ds.Tables(0, 1))
ReportViewer1.LocalReport.ReportEmbeddedResource = "Harsha_Bill.Invoice.rdlc"
ReportViewer1.LocalReport.DataSources.Clear()
ReportViewer1.LocalReport.DataSources.Add(rds)
ReportViewer1.RefreshReport()

Catch ex As Exception
MessageBox.Show(ex.Message, My.Application.Info.Title, MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub

End Class

At a guess, it's the source name: I suspect that "dsSales" is not the name of the data in the table itself. Try this:

VB

Dim dt as DataTable = ds.Tables(0);
Dim rds = new ReportDataSource(dt.TableName, dt)

I would also strongly suggest that you use Using blocks, instead of manually closing and disposing - that way, even if there is an error the system will clear up after you.
