Scroll performance issue

Hi Roger,

That's odd, we don't see the same thing in the WPF version.  In fact the WPF version was built for speed in large documents.  When we PgDn scroll in a very large 10,000 line document, it is flipping by very fast and only takes a few (maybe about 5) seconds to reach the end.  See if you can duplicate this issue in our SDI Editor demo. 

If not, then please make a new simple sample project that shows the issue and send it to our support address. Reference this post and rename the .zip file extension so it doesn't get spam blocked.  Perhaps you are doing something in your setup that causes it to take extra time.

Sorry but we don't support images in the forums.  You can link to an image that you've posted elsewhere though.

Thanks for the reply.

Sorry, as you say, it seems our problems apparently.

We added new ClassificationTags of two different colors.

Thereby, loop processing in the ActiproSoftware.Windows.Controls.SyntaxEditor.Implementation.RenderingCache.CreateSequencedRuns is has increased, It seems to influence to the deterioration of performance.

So we have a question.

Without coloring process while the scrolling, we want to do the coloring process after the scrolling is complete.

Is there a way to achieve these goals?

Also, is there a way to improve the performance another way?

Hi Roger,

It would probably help us answer your question better if you make a new simple sample project that shows the issue and what you are currently doing.  Also describe more about what you are trying to color and if it's something where you know the ranges that will be colored ahead of time or if you have to do it on the fly.  Send your sample to our support address and reference this post.  Rename the .zip file extension so it doesn't get spam blocked.  Thanks!
