Cannot get Crystal Reports 2008 to display data.

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.
