What I have tried:

Dim outputFormat As String = "JPEG" '' TryCast(sender, Button).Text.ToLower()
                Dim renderedBytes As Byte()
                If outputFormat = "JPEG" Then
                    renderedBytes = RV.LocalReport.Render(reportType, "<DeviceInfo><OutputFormat>JPG</OutputFormat></DeviceInfo>")
                Else
                    renderedBytes = RV.LocalReport.Render(reportType, "<DeviceInfo><OutputFormat>PNG</OutputFormat></DeviceInfo>")
                End If

                Using Stream As New FileStream(strfilepath & "\" & "JPG" & "\" & strfilename & ".JPEG", FileMode.Create)
                    Stream.Write(renderedBytes, 0, renderedBytes.Length)
                End Using
