ListBox 사용자 지정 항목 인쇄

Question

WPF를 처음 사용하고 컨트롤에 표시되는대로 내 ListBox 컨트롤 사용자 지정 항목을 인쇄하려고합니다. 목록 상자 항목의 구조는 다음과 같다 :

<StackPanel Orientation="Vertical" HorizontalAlignment="Center" x:Name="PanelContainer"> 
    <Border CornerRadius="5" BorderThickness="2" BorderBrush="DarkBlue" x:Name="PanelMessage"> 
     <StackPanel Orientation="Horizontal" Background="{Binding Color}"> 
      <StackPanel Orientation="Vertical"> 
       <Image Source="{Binding SenderImage}" Width="50" Height="50" Stretch="Uniform" /> 
       <TextBlock Text="{Binding Sender}" TextAlignment="Center" Width="50" TextWrapping="Wrap" /> 
      </StackPanel> 
      <StackPanel Orientation="Horizontal" VerticalAlignment="Center"> 
       <Image Source="{Binding IsRead}" Width="15" Height="15" Stretch="Uniform" 
         VerticalAlignment="Top" /> 
       <StackPanel Orientation="Vertical" Margin="5"> 
        <TextBlock x:Name="txtbTime" Text="{Binding TimeCreated}" /> 
        <TextBlock x:Name="txtbMessage" Text="{Binding MessageBody}" 
           TextWrapping="WrapWithOverflow" HorizontalAlignment="Stretch" /> 
       </StackPanel> 
      </StackPanel> 
     </StackPanel> 
    </Border> 
</StackPanel> 

내 인쇄 코드는 다음과 같다 :

UIElement myListBoxItem = 
    (UIElement) (lbMessages.ItemContainerGenerator.ContainerFromItem((Message) lbMessages.Items[i])); 
if (myListBoxItem != null) 
{ 
    string element = XamlWriter.Save(myListBoxItem); 
    MemoryStream ms = new MemoryStream(); 
    XamlWriter.Save(element, ms); 
    ms.Seek(0, SeekOrigin.Begin); 
    object obj1 = XamlReader.Load(ms); 
    BlockUIContainer bc = new BlockUIContainer(); 
    bc.Child = obj1 as UIElement; 
    fd.Blocks.Add(bc); 
    ms.Close(); 
} 
PrintDialog dialog = new PrintDialog(); 
if (dialog.ShowDialog() == true) 
    dialog.PrintDocument(idpSource.DocumentPaginator, "Hello WPF Printing."); 

내 결과가 명확 페이지입니다.

감사합니다. 감사합니다.

DataGrid 및 ListView에 대해 동일한 문제가 있으며이 확장명으로 해결했습니다. ListBox에이 코드를 적용하면 도움이 될 수 있기를 바랍니다.

일부 검색 후 나는 다음과 같은 솔루션을 주위에 작품을 발견했습니다. 2. 값이있는 테이블을 생성하십시오. 3. 테이블 보유 값을 인쇄하십시오.

코드 :

foreach (Message message in lbMessages.Items) 
      { 

       TableRowGroup _MessageContainer = new TableRowGroup(); 

       // Rows 
       TableRow _TimeCreated = new TableRow(); 
       TableRow _imageRow = new TableRow(); 
       TableRow _TimeRow = new TableRow(); 

       // first row 
       TableCell xcell = new TableCell(new Paragraph(new Run("Image is here"))); 
       xcell.RowSpan = 2; 
       TableCell _TimeCell = new TableCell(new Paragraph(new Run(message.TimeCreated.ToString()))); 
       _TimeCreated.Cells.Add(xcell); 
       _TimeCreated.Cells.Add(_TimeCell); 

       // Second Row. 
       xcell = new TableCell(new Paragraph(new Run(message.MessageBody))); 
       _imageRow.Cells.Add(xcell); 

       // Third Row 
       xcell = new TableCell(new Paragraph(new Run(message.Sender))); 
       xcell.ColumnSpan = 2; 

       _MessageContainer.Rows.Add(_TimeCreated); 
       _MessageContainer.Rows.Add(_imageRow); 
       _MessageContainer.Rows.Add(_TimeRow); 

       Table xtable = new Table(); 
       xtable.RowGroups.Add(_MessageContainer); 
       xtable.CellSpacing = 3; 
       xtable.Background = Brushes.White; 

       document.Blocks.Add(xtable); 
}
