如何将多个 FlowDocumentReader 添加到 StackPanel?
感谢Leom的回答我是能够通过将 FlowDocument 包装在 FlowDocumentReader 中来将其添加到 StackPanel。
但现在我有两个问题:
- 似乎只添加了第一个 FlowDocumentReader,其余的被忽略,
- 有一个不需要的边距,我无法摆脱
如何我可以向 StackPanel 添加多个 FlowDocumentReader 吗?

Title="Window1" Height="200" Width="300">
<StackPanel Margin="10">
<ContentControl x:Name="MainArea"/>

using System.Windows;

namespace TestFlowdoc23432
{
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
StackPanel sp = new StackPanel();
TextBlock tb1 = new TextBlock();
tb1.Text = "first text block";
sp.Children.Add(tb1);
TextBlock tb2 = new TextBlock();
tb2.Text = "second text block";
sp.Children.Add(tb2);
sp.Children.Add(GetFlowDocumentReader("first flow document reader"));
sp.Children.Add(GetFlowDocumentReader("second flow document reader"));
MainArea.Content = sp;
}
FlowDocumentReader GetFlowDocumentReader(string text)
{
FlowDocumentReader fdr = new FlowDocumentReader();
FlowDocument fd = new FlowDocument();
fdr.Document = fd;
fdr.Margin = new Thickness(0);
Paragraph par = new Paragraph();
par.Margin = new Thickness(0);
fd.Blocks.Add(par);
Run r = new Run(text);
par.Inlines.Add(r);
return fdr;
}
}
}
Thanks to Leom's answer I was able to add a FlowDocument to a StackPanel by wrapping it in a FlowDocumentReader.
But now I have two problems:
- it seems only the first FlowDocumentReader is added and the rest ignored
- there is an unwanted margin that I can't get rid of
How can I add multiple FlowDocumentReaders to a StackPanel without the unwanted margin?

要使文本显示在左侧,您需要在流程文档上设置 pagepadding 属性,如下所示:
您似乎只获得第一个读者的原因是因为它填充了可用空间(将其移动到第一个对象,您将看不到文本块)。
如果将 FlowDocumentReader 更改为 FlowDocumentScrollViewer 并使用 VerticalScrollBarVisibility 属性,则可以获得所需的效果。以下是应用了更改的 GetFlowDocumentReader 方法:
To make the text appear to the left you need to set the pagepadding property on your flowdocument as follows:
the reason that you only seem to get the first reader is becuase it fills the space available (move it to be the first object and you will not see the textblocks).
If you change the FlowDocumentReader to be a FlowDocumentScrollViewer and use the VerticalScrollBarVisibility property then you can get the desired effect. The following is your GetFlowDocumentReader method with the changes applied:
