WPF RichTextBox性能 [英] WPF RichTextBox Performance

问题描述

当加载50KB文本文档时，WPF的RichTextBox控件的性能确实很慢。滚动慢速并按Ctrl-A选择所有文本需要10秒钟以上。 （这在记事本上是不经意的。）

WPF's RichTextBox control's performance is real slow when a 50KB text document is loaded. Scrolling laggy and pressing Ctrl-A to select all the text takes more than 10 seconds. (This is intantaneous on Notepad).

我没有做任何奇特的位图效果。这正常吗？甚至在一个空的RichTextBox上键入内容似乎也比正常情况有些滞后。

I'm not doing any fancy bitmap effects. Is this normal? Even typing on an empty RichTextBox seems a bit laggy than normal.

是否有此修复程序？备择方案？谢谢！

Are there fixes for this? Alternatives? Thanks!

推荐答案

您可能需要考虑使用其他文本框控件。

You might need to consider using a different text box control.

Daniel Grunwald完全从零开始为SharpDevelop编写了Wpf文本编辑器。它称为AvalonEdit，并且在codeproject上有一篇不错的文章：

Daniel Grunwald has written the Wpf text editor for SharpDevelop completely from scratch. It is called AvalonEdit and a good article is on codeproject:

看来他已经为大文件。
