RichTextBox在Windows 7和Vista上缓慢刷新 [英] RichTextBox slow refreshing on Windows 7 and Vista

问题描述

你好，

我对RichTextBox的性能（打字时）有问题。

这是我的简单窗口：
$


< 窗口
x ： 类 =" RichTextBoxPerformance.Window1"

xmlns = http://schemas.microsoft.com/winfx/2006/xaml/演示文稿

xmlns ： x = http://schemas.microsoft.com/winfx/2006/xaml

标题 =" RichTextBox测试"
高度 =" 300" 宽度 =" 300">

< RichTextBox
/>

< / 窗口 >

后面没有代码。我的示例基于WPF版本3.5。我也建立了WPF版本4.0的示例存在同样的问题。

如果我在Windows 7（32位和64位）或Vista上运行此示例，RichTextBox刷新文本的速度很慢如果我在XP SP3上运行它，那么RichTextBox刷新速度非常快。

问题是什么，我该如何解决这个问题，或者这是一个错误？

感谢您的帮助。

您好JProud，

您是否为RichTextBox加载了一个大尺寸的文件？请提供更多信息或步骤以便我们重现这个问题？

实际上，我的操作系统是windows7，但之前我没有遇到过同样的问题。你可以看看下面谈到类似问题而没有完美答案。但我认为可以提供一些提示：

Hi together,

I've a problem with the Performance (while typing) of the RichTextBox.

This is my simple window:

<Window x:Class="RichTextBoxPerformance.Window1"
xmlns=http://schemas.microsoft.com/winfx/2006/xaml/presentation
xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml
Title="RichTextBox Test" Height="300" Width="300">
<RichTextBox />
</Window>

There is no code behind. My sample is based on WPF Version 3.5. I've also built a sample with WPF Version 4.0 and there is the same problem.

If I run this sample on a Windows 7 (32Bit and also 64Bit) or on Vista the RichTextBox refreshs the text very slow. If I run this on a XP SP3 the RichTextBox refreshs quite fast.

What is the Problem, how can i solve this, or is this a bug?

Thanks for every help.

Hi JProud,

Did you load a file of a big size to the RichTextBox? Could you please provide more information or steps so we can reproduce the issue?

Actually, my operation system is windows7, but I did not meet the same issue before. You can take a look at the tread below which talks about a similar issue without a perfect answer. But I think it can provide some hints:
