[Solved] ASP.Net RLDC Export Error: Thread is abored

I have below mentioned codes

Try
    If Session("UserID") = Nothing Then
        DBH.SessionExpired()
    Else
        Dim CustomerId As Int64 = ddCustomers.SelectedValue
        Dim MonthId As Integer = ddMonths.SelectedValue
        Dim InvDate As Date = TxtInvoiceDate.Text
        Dim TripIdList As String = ""
        Dim SqlStr As String = "ViewTripsDetails '" & Session("CompanyId") & "','" & Session("FyId") & "','" & CustomerId & "','" & MonthId & "','" & TripIdList & "' "
        ReportViewer1.ProcessingMode = ProcessingMode.Local
        ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Reports/RptInvoice.rdlc")
        Dim DataSetInv As DsInvoice = GetData(SqlStr)
        Dim datasource As New ReportDataSource("InvData", DataSetInv.Tables(0))
        ReportViewer1.LocalReport.DataSources.Clear()
        ReportViewer1.LocalReport.DataSources.Add(datasource)
        Dim warnings As Warning()
        Dim streamIds As String()
        Dim contentType As String
        Dim encoding As String
        Dim extension As String
        Dim bytes As Byte() = ReportViewer1.LocalReport.Render("PDF", Nothing, contentType, encoding, extension, streamIds, warnings)
        Response.Clear()
        Response.Buffer = True
        Response.Charset = ""
        Response.Cache.SetCacheability(HttpCacheability.NoCache)
        Response.ContentType = contentType
        Response.AppendHeader("Content-Disposition", "attachment; filename=RDLC." & extension)
        Response.BinaryWrite(bytes)
        Response.Flush()
        Response.End()
    End If
Catch ex As Exception
    msg.Text = ex.Message.ToString
    DBH.ShowTstr(DBH.ToastType.Error, ex.Message.ToString, "Opps ! There is an error")
End Try

By the help of above codes I would like to generate and downlaod the pdf file from rdlc report.

but it is throwing error "Thread is abored".

Also not downlod the report in pdf form.
