I've created a simple report with 1 parameter field "country" and 1 parameter field that allows multiple values "states". I added "country" to the Header and "states" to Details.

Now, I have written VB codes to pass parameters into the fields. "country" displays well but "states" only display the 1st one. This is the code I used:


    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
        Dim oRpt As New ReportDocument
        oRpt.Load(Server.MapPath("/TestingApp/CrystalReport1.rpt"),
OpenReportMethod.OpenReportByTempCopy)
        CrystalReportViewer1.ReportSource = oRpt

        Dim paramFields As ParameterFields =
CrystalReportViewer1.ParameterFieldInfo
        addValueToParameterFields(paramFields("country"), "Case 123")
        addValueToParameterFields(paramFields("states"), "123")
        addValueToParameterFields(paramFields("states"), "456")
        addValueToParameterFields(paramFields("states"), "789")

        CrystalReportViewer1.ParameterFieldInfo = paramFields
        CrystalReportViewer1.DataBind()
    End Sub

    Private Sub addValueToParameterFields(ByRef paramField As
ParameterField, ByVal val As String)
        Dim discreteVal As New ParameterDiscreteValue
        discreteVal.Value = val
        paramField.CurrentValues.Add(discreteVal)
   End Sub


Can someone tell me what is wrong?
