使用自定義打印模板（用戶控件）在Silverlight 4中進行多頁打印

我需要使用自定義打印模板打印多個頁面的一些幫助。打印模板（一個Silverlight用戶控件）由兩個文本塊（標題和內容顯示並隨後打印相應的文本）組成。我遇到的問題是它唯一能夠打印1頁，我如何擴展它以打印多個頁面。這是工作流程 - 第一次嵌入在子窗口（樣定製消息框的）文本塊上顯示使用自定義打印模板（用戶控件）在Silverlight 4中進行多頁打印

含量（待印刷其可以是非常大）。
此內容需要打印，所以我創建了一個自定義打印模板，它將分別打印標題和內容。
現在，我不確定如何將其擴展爲打印多個頁面。

這裏是我的XAML -

<StackPanel VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="10,10,10,10" > 
     <Border HorizontalAlignment="Stretch" VerticalAlignment="Stretch" CornerRadius="10" BorderThickness="5" Background="White" Height="50" > 
      <TextBlock HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="2" TextWrapping="Wrap" Name="TitleTextBlock" FontSize="16" 
         TextAlignment="Center" FontFamily="Times New Roman" FontStyle="Italic" FontWeight="SemiBold" > 
      </TextBlock> 
     </Border> 
     <Border HorizontalAlignment="Stretch" VerticalAlignment="Stretch" CornerRadius="10" Margin="0,10,0,0" BorderThickness="5" Background="White" Height="950" > 
      <TextBlock HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="10" TextWrapping="Wrap" Name="ContentTextBlock" FontSize="14" 
         FontFamily="Times New Roman" FontWeight="Normal" > 
      </TextBlock> 
     </Border> 
</StackPanel>

和我的代碼 -

Private Sub btnPrint_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) 
    printDoc.Print("MyTest") 
End Sub 

Private Sub printDoc_PrintPage(ByVal sender As Object, ByVal e As PrintPageEventArgs) 

    Dim printPage As New PrintingPageTemplate 

    'printPage.PageTitle = Me.Title.ToString 
    'printPage.PageContent = Me.txtMessage.Text 
    printPage.TitleTextBlock.Text = Me.Title.ToString 
    printPage.ContentTextBlock.Text = Me.txtMessage.Text 'The txtMessage is a text block which consists of data to be printed and it can have very large content 

    e.PageVisual = printPage 
    'e.HasMorePages = True ' This doesn't work 
End Sub

需要一些邏輯將檢查TitleTextBlock的總規模，創造PrintingTemplate的新實例。有人可以請指出我怎麼能做到這一點？（我希望我能夠爲我的問題提供足夠的信息）。
