Question

我正在尝试打印FlowDocument。在花了大量时间尝试多个页面后，我失败并选择了更简单的东西，但我现在无法解释文本何时没有输出到页面。这一定是我想到的雪盲。下面有两个表，在两个显示器上放置一个转换器，通过FlowDocument的DataContext填充值。

<Table>
    <Table.Columns>
        <TableColumn Width="Auto"/>
        <TableColumn Width="34"/>
        <TableColumn Width="Auto"/>
    </Table.Columns>
    <TableRowGroup>
        <TableRow>
            <TableCell>
                <Paragraph>
                    <Image Source="{Binding Icon,Converter={StaticResource IconConverter},ConverterParameter=32}" Width="32" Height="32"/>
                </Paragraph>
            </TableCell>
            <TableCell>
                <Paragraph>
                    <TextBlock Text="{Binding Name,Converter={StaticResource dbg}}" TextWrapping="Wrap" TextTrimming="CharacterEllipsis" VerticalAlignment="Center" FontSize="18" Foreground="Black" />
                </Paragraph>
            </TableCell>
            <TableCell>
                <Paragraph>
                    <TextBlock Text="Static text works fine" TextAlignment="Right"  />
                    <TextBlock Text="Static text works here too fine" TextAlignment="Right"  />
                </Paragraph>
            </TableCell>
        </TableRow>
    </TableRowGroup>
</Table>
<BlockUIContainer>
    <Line Stretch="Fill" Stroke="DarkBlue" X2="1"/>
</BlockUIContainer>

使用以下方式打印文档：

PrintDialog dlg = new PrintDialog();
if(dlg.ShowDialog() == true) {
  int margin = 5;
  Size pageSize = new Size(dlg.PrintableAreaWidth - margin * 2, dlg.PrintableAreaHeight - margin * 2);
  FlowDocument document = WPFUtils.LoadFlowDocument(System.IO.Path.Combine(Utils.GetApplicationPath(), "AccountPrintView.xaml"), account); // loads the document from a XAML file
  IDocumentPaginatorSource paginator = document as IDocumentPaginatorSource;
  paginator.DocumentPaginator.PageSize = pageSize;
  dlg.PrintDocument(paginator.DocumentPaginator, "Print output");
}

我有点想到这个，我看不出问题。如果有人能说清楚的话，我真的很感激。

这本身并不是一个真正的答案，但您是否可以使用FlowDocumentReader？它已经在Ctrl-P上预先连接了打印内容（并公开了“打印”方法）......说，您可以试试这个：Printing a Windows Foundation Presentation FlowDocument

WPF：打印FlowDocument
