在DocumentViewer中右键单击TextBox时发生异常 [英] Exception while Right-Click on TextBox within DocumentViewer
问题描述
您好，
我正在创建简单的DocumentViewer，然后将Xps文档加载到其中，然后在文档的第一页上创建TextBox控件.右键单击TextBox会导致从 PresentationCore 引发的不清楚的异常，我无法调试也不能低估该异常.任何帮助表示赞赏.详细信息在下面.
我有以下 XAML :
Hello,
I'm creating simple DocumentViewer, then load Xps document into it, then create the TextBox control on the first page of the document. Right-click on the TextBox leads to unclear exception thrown from PresentationCore , which I cannot debug nor understant. Any help is appreciated. Details go below.
I have the following XAML :
<Window x:Class="Test.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Grid>
<DocumentViewer Name="documentViewer">
</DocumentViewer>
</Grid>
</Window>
以及以下代码:
And the following code :
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
XpsDocument xpsDocument = new XpsDocument("C:/Temp/test.xps", FileAccess.Read);
FixedDocumentSequence docSequence = xpsDocument.GetFixedDocumentSequence();
FixedDocument doc = docSequence.References[0].GetDocument(false);
documentViewer.Document = doc;
PageContent pageContent = doc.Pages[0];
FixedPage fixedPage = pageContent.GetPageRoot(false);
TextBox tb = new TextBox();
tb.Width = 100;
tb.Height = 100;
fixedPage.Children.Add(tb);
}
}
基本上我是怎么做的:
Basically what I do:
- 我加载Xps文档并在DocumentViewer中显示
- 创建TextBox控件并将其添加到FixedDocument第一页的Children集合中
一切正常，但是如果我在运行时右键单击TextBox，我会立即从 PresentationFramework 收到以下异常:
消息: 不能将"System.Windows.Data.MultiBindingExpression"值分配给对象"System.Windows.Controls.Primitives.RepeatButton"的属性"Visibility".找不到与"und"相关的非中性文化.对象'System.Windows.Data.MultiBinding'出错."

Everything works fine, but if I right click on the TextBox in the run-time I immediately get the following exception from PresentationFramework :

推荐答案
其他发现:问题似乎与TextBox控件的上下文菜单有关.如果我添加以下代码
Additional findings: it seems like the problem has something to do with the Context Menu of the TextBox control. If I add the following code
tb.ContextMenu = null;
右键单击仅显示基础DocumentViewer的上下文菜单，不会引发异常.但是，TextBox的ContextMenu仍未显示.
Right-click just shows the context menu of the underlying DocumentViewer and doesn't fire exception. However, ContextMenu of the TextBox is still not shown.
这篇关于在DocumentViewer中右键单击TextBox时发生异常的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
