I am using dotnetnuke to show my report but I don't know why I am getting this exception.



This is my telerik report project code and I have added this reference in my website.

Partial Public Class jobReport
    Inherits Telerik.Reporting.Report
    Public Sub New()
        InitializeComponent()
        Me.datasource = Nothing
    End Sub


    Private Sub jobReport_NeedDataSource(ByVal sender As Object, ByVal e As System.EventArgs)
        ' Take the Telerik.Reporting.Processing.Report instance
        Dim report As Telerik.Reporting.Processing.Report = DirectCast(sender, Telerik.Reporting.Processing.Report)


        ' Transfer the processing Parameter value to the parameter of the select command         
        Me.SqlDataAdapter1.SelectCommand.Parameters("@p_JobID").Value = report.Parameters("ID").Value


        ' and set the adapter as it's DataSource         
        report.DataSource = Me.SqlDataAdapter1
    End Sub



End Class


This is my website code and i am adding one parameter here and passing a value from query string.

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load


        If Not IsPostBack Then


            Dim nJobID As Integer
            nJobID = Request.QueryString("JobID")
            If nJobID <> 0 Then
                Dim rptJobList As New jobReport
                Dim reportParameter1 As New Telerik.Reporting.ReportParameter()
                reportParameter1.Name = "ID"
                reportParameter1.Text = "Enter Value for Parameter1"
                reportParameter1.Type = Telerik.Reporting.ReportParameterType.Integer
                reportParameter1.AllowBlank = False
                reportParameter1.AllowNull = False
                reportParameter1.Value = nJobID
                reportParameter1.Visible = True
                rptJobList.ReportParameters.Add(reportParameter1)
                rptJobList.ReportParameters("ID").Value = nJobID
                reportViewer.Report = rptJobList
            End If


        End If
    End Sub
