Opening a crystal report at a specific record (ASP.Net with VB.Net) linked to SQL backend

Hi,

I have a crystal report that is linked to a sql server 2000 database table via OLE DB (ADO) what is the best practice for opening the report to show only a specific record (essential that the user cannot see other records)

Is it:
1) Open the report and pass a parameter for the key field. If yes could you please provide an example.
2) Create a dataset with just the record relating to the key field and set the reports datasource to the dataset. This is working for the attached code but if there is a simpler way then I'd be happy to use it rather than having to do this for every report I need to open.
3) Some other way


Dim reportPath As String = Server.MapPath("Test123.rpt")
        Dim myConnection As New SqlConnection
        myConnection.ConnectionString = ConnectionStrings("MyDB").ConnectionString
        Response.Write(myConnection.ConnectionString)
        Dim MyCommand As New SqlCommand()
        MyCommand.Connection = myConnection
        MyCommand.CommandText = "Select * from TableName where FPlanID = " & intPlanID 'session variable
        MyCommand.CommandType = CommandType.Text
        Dim MyDA As New SqlDataAdapter()
        MyDA.SelectCommand = MyCommand
        Dim myDS As New DataSet()
        Dim rpt As New ReportDocument
        MyDA.Fill(myDS, "TableName")
        rpt.Load(reportPath)
        rpt.SetDataSource(myDS)
        rpt.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, False, "ExportedReport")

I'm having an issue with option 2 as the report now contains sub reports so I'm getting a login error when the report opens as the sub report references a different but related table, hmmm.

I would usually define a RowFilter for a DataTable.DefaultView, and bind to the DataTable.DefaultView.  I would think that you could do that with a Crystal Report.

Simple example:

Dim dv As New DataView(Me.DataSet1.Tables(0))
dv.RowFilter = "Name = 'Bob' "
Dim rpt As New CrystalReport1()
rpt.SetDataSource(dv)
