Cannot get Crystal Reports 2008 to display data.

Open original thread
Built a CR using following data taken from a database and loaded into a dataset. Below is the code to construct the dataset and set up the report. I put 2 Datagridviews on the form to display the data. Both grids display data, but the report shows nothing.

Dim ds As New rptDataSet 'DataSet I created using the IDE
Dim t as DataTable = ds.TmsSchedule  'Primary DataTable with Source material
Dim s As DataTable = ds.School       'Second table with Student assignments
' Pull the data from the database and put it in the dataset.
Dim sc = From tms In db.TmsSchedules _
     Join sch In db.Schools On sch.SchoolDate Equals tms.schDate _
     Where tms.schDate >= firstDate And tms.schDate <= lastDate _
     Select tms.schDate, sch.SchoolDate ' etc.
Dim r As DataRow
Dim rs As DataRow
For Each dr In sc
   r = t.NewRow()
   r("schDate") = dr.schDate
       ' etc.
   rs = s.NewRow()
   rs("SchoolDate") = dr.SchoolDate
       ' etc.
' All the above works and display in the DataGridViews on the report
' Below is exactly the same as in another report, but nothing displays.
Dim objRpt As New rptSchedule 'Report I built from the above Dataset
objRpt.SetDataSource(ds)          'Point the report to the dataset
CrystalReportViewer1.ReportSource = objRpt 'Set reportviewer to the report
CrystalReportViewer1.Refresh()    'Refresh the report.
