SharpDevelop Community

Hi all,

I tried to integrate the ICSharpCode.TextEditor.dll into my c# app. using .NET 2005 develop environment to create an editor with syntax highlighting functionality.

Everything works fine, as a template - I used the CSharpCodeCompletion example as well as the SharpPad example.

The problem is, my own solution as well as the two mentioned examples above are extrem slow while scrolling in a document with just 100 lines of code.

I have read something about performance problems concerning the ICSharpCode.TextEditor.dll - is there any solution available right now?

I am wondering because if I try the compiled Version of the SharpDevelopWroxEdition the TextEditor is very fast.

Thanks, Til
 

There are known performance problems with lots (>500) of folding markers or text markers, but that isn't your problem. 

The text drawing has changed a lot since the SharpDevelopWroxEdition. For a few users, the new way seems to be slow, but we cannot find the cause because we cannot reproduce the problem.

It could help if you list your system configuration (incl. graphics driver version) as well as 3rd-party software running in the background that could cause this.

Daniel's covered pretty much everything. The only other thing to do is try running it outside of SharpDevelop since scrolling can be slow if you're running your app under the debugger.
