[DevExpress Support Team: CLONED FROM KA18788: Visual Studio 2013, 2012, 2010 performance is very slow when a page with ASP.NET controls is opened in Designer]
So now we're up to Visual Studio 2017 and the Devexpress controls are as slow as ever when working in the Designer.
At the moment, each time I change something in the HTML code, it takes about 45 seconds for the page to "refresh" before I can work again.
My PC is an i7, 7th generation with 32GB of RAM, SSD hard drive.
I've made a little video so prospective Devexpress users can see what they are in for.
(Sorry it's in swf. I recorded it in Jing.)
Hi Daniel,
Would you please send me your sample project for analysis? We will research it and see if we can solve it.
Hi,
I've taken out and commented out most of the code and attached the project.
The page to look at is Collections -> Investigations.aspx
Rename a control in the split view and save or move between the design and source.) Most likely you'll wait for up to a minute. From time to time, this causes VS 2017 to crash as well.
Please don't suggest splitting the controls into user controls, I just don't have the time to do that.
Also,
4, All other solutions that have been suggested previously in tickets - doesn't help
Regards,
Daniel.
Hi,
We need additional time to research this. Please bear with us.
How long do you expect this to take?
Daniel,
While we don't have any ETA on this, we're working on this issue and will update this thread once we have any results.
