How to directly print radgridview to Telerik report viewer ?

This is my code to print Radgridview
Public Sub ImprimirListado()
        'Muestro la ventana de impresión del RadGridView
        Try
            Dim Impreso As New RadPrintDocument
            Impreso.AssociatedObject = Me.RadGridView
            Dim VistaPrevia As RadPrintPreviewDialog = New RadPrintPreviewDialog(Impreso)
            VistaPrevia.ThemeName = "Office2013Light"
            VistaPrevia.WindowState = FormWindowState.Maximized
            VistaPrevia.ShowDialog()
        Catch ex As Exception
            MessageBox.Show(String.Format("Error en: {0}", Me.Name) + Chr(13) + "Evento: ImprimirListado" + Chr(13) + "Mensaje: " & ex.Message, "Atención", MessageBoxButtons.OK, MessageBoxIcon.Warning)
        End Try
