No records shown in report ?

Question

I have created a crystal report using ado.net dataset ("OleDB to SQL server database") and load it to a crystal report viewer in testreport2.aspx. No errors when run but no records where shown.
There is no problem with the data table return from GeneralProduct class as the DropDownList1 contains 30 item and textbox1 displays a total of 30 records from data table return.
=================================================
Imports CrystalDecisions.CrystalReports.Engine
Partial Class testreport2
    Inherits System.Web.UI.Page
    Private oRpt As ReportDocument
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            CrystalReportViewer1.EnableDatabaseLogonPrompt = False
            oRpt = New ReportDocument
            oRpt.Load(Server.MapPath("CrystalReport2.rpt"))
            Dim _GeneralProduct As New GeneralProduct
            _GeneralProduct.GetGeneralProductDataTable()
            TextBox1.Text = "Record Count [" & CStr(_GeneralProduct.RecordsCount) & "]"
            oRpt.SetDataSource(_GeneralProduct.oDataTable)
            CrystalReportViewer1.ReportSource = oRpt
            CrystalReportViewer1.DataBind()
            CrystalReportViewer1.RefreshReport()
            dd.DataTextField = "ProductID"
            dd.DataValueField = "ProductID"
            dd.DataSource = _GeneralProduct.oDataTable
            dd.DataBind()
            _GeneralProduct = Nothing
        End If
        If IsPostBack Then
            oRpt = Session.Item("oReport")
            CrystalReportViewer1.ReportSource = oRpt
        End If
    End Sub
    Protected Sub Page_Unload(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Unload
        Session.Add("oReport", oRpt)
    End Sub
End Class

Hi there,
Using Visual Studio 2008, I have created a crystal report with ado.net dataset ("OleDB to SQL server database") and load it to a crystal report viewer in testreport2.aspx. No errors occurs when run but no records where shown.
There is no problem with the data table return from GeneralProduct class as the DropDownList1 contains 30 item and textbox1 displays a total of 30 records from data table return.
Imports CrystalDecisions.CrystalReports.Engine
Partial Class testreport2
    Inherits System.Web.UI.Page
    Private oRpt As ReportDocument
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            CrystalReportViewer1.EnableDatabaseLogonPrompt = False
            oRpt = New ReportDocument
            oRpt.Load(Server.MapPath("CrystalReport2.rpt"))
            Dim _GeneralProduct As New GeneralProduct
            _GeneralProduct.GetGeneralProductDataTable()
            TextBox1.Text = "Record Count [" & CStr(_GeneralProduct.RecordsCount) & "]"
            oRpt.SetDataSource(_GeneralProduct.oDataTable)
            CrystalReportViewer1.ReportSource = oRpt
            CrystalReportViewer1.DataBind()
            CrystalReportViewer1.RefreshReport()
            DropDownList1.DataTextField = "ProductID"
            DropDownList1.DataValueField = "ProductID"
            DropDownList1.DataSource = _GeneralProduct.oDataTable
            DropDownList1.DataBind()
            _GeneralProduct = Nothing
        End If
        If IsPostBack Then
            oRpt = Session.Item("oReport")
            CrystalReportViewer1.ReportSource = oRpt
        End If
    End Sub
    Protected Sub Page_Unload(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Unload
        Session.Add("oReport", oRpt)
    End Sub
End Class
