在托管的WPF复合控件中的奇怪的滚动条UI [英] Weird scrollbar UI in hosted WPF composite control

问题描述

我的窗口应用程序主机AvalonEdit（有问题的复合WPF控件）在其形式之一，以满足其文本编辑要求。这里是我使用的代码：

My windows forms application hosts AvalonEdit (the composite WPF control in question) in one of its forms to cater to its text editing requirements. Here's the code I use:

WPFHost = gcnew ElementHost();
TextField = gcnew AvalonEdit::TextEditor();
WPFHost->Dock = DockStyle::Fill;
WPFHost->Child = TextField;

TextField->Options->AllowScrollBelowDocument = false;
TextField->Options->EnableEmailHyperlinks = false;
TextField->Options->EnableHyperlinks = true;
TextField->Options->RequireControlModifierForHyperlinkClick = true;
TextField->ShowLineNumbers = true;

ContainerControl->Controls->Add(WPFHost); // the container is a panel

代码编译并执行得很好，除了滚动条 - http://dl.dropbox.com/u/2584752/avalonEditBug.png 。右键点击栏左侧会产生一个ArgumentOutOfRange异常。

The code compiles and executes fine, except for the scrollbars - http://dl.dropbox.com/u/2584752/avalonEditBug.png . Right clicking on what's left of the bar raises an ArgumentOutOfRange exception.

奇怪的是，当我尝试在新创建的示例中托管控件时，我无法重现该问题项目。 'mI使用最新版本的文本编辑器并安装了所有必需的程序集。

Strangely, I wasn't able to reproduce the issue when I tried hosting the control in a newly created sample project. 'mI using the latest build of the text editor and have all the requisite assemblies installed.

编辑：在用户控件中包含编辑器也没有帮助。

Wrapping the editor in a usercontrol doesn't help either.

推荐答案

我已经为这个线程中提到的问题实现了一个解决方法[使用WinForms ScrollBar同步WPF ScrollViewer ]。

I've implemented a workaround for the issue as mentioned in this thread [ Synchronizing a WPF ScrollViewer with a WinForms ScrollBar ].
