C# 设置Rtf文本时，RichEditBox（UWP）忽略字体和前景
我正在使用C# 设置Rtf文本时，RichEditBox（UWP）忽略字体和前景,c#,xaml,windows-runtime,uwp,windows-10,C#,Xaml,Windows Runtime,Uwp,Windows 10,我正在使用RichEditBox，在保存和恢复Rtf文本时遇到一些问题 以下是我导出的Rtf文本示例，正如您所看到的，正确保存了不同的前景色和字体系列（我已手动缩进以便于阅读）： 问题：我打电话 EditBox.Document.SetText(TextSetOptions.FormatRtf, myRtfString); 文本将加载到控件中，但字体系列和前景色将被完全忽略。 我已经试过打电话： EditBox.Document.ApplyDisplayUpdates(); 这并不能解决问题
RichEditBoxEditBox.Document.SetText(TextSetOptions.FormatRtf, myRtfString);
EditBox.Document.ApplyDisplayUpdates();

此问题目前无法通过以下代码在最新的windows 10 build 14393中复制：
XAML代码
... mc:Ignorable="d" Loaded="Page_Loaded">
<StackPanel Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<RichEditBox x:Name="EditBox" Height="400" Margin="40" >
</RichEditBox>
</StackPanel>
如果您仍然希望在您的环境中找到解决方案，请尝试以RichEditTextBox
的样式查找“聚焦视图状态”下的以下代码，并将其注释掉。有关这方面的更多详细信息，请参考
我这边的结果是：
非常感谢您的回答！我已经删除了这些可视状态（我用我正在使用的完整样式编辑了我的答案），我只是按照您的建议将SetText调用移动到加载的事件处理程序中（我在页面构造函数中调用它），它解决了这个问题。干杯
