Hi, please find attached a very basic demo (built with version 11.2), which illustrates the following point:
Our users are complaining about the slow scrolling performance when scrolling down the grid.
Is there a reason for this inconsistency?
Hi,
A support case has been created and you should be contacted shortly. This sounds similar to another issue we recently fixed and is in testing currently. The Developer Support Engineer should verify the reported issue here is the same that we recently fixed and if so you'll be notified when the fix is released.
Please refrain from creating multiple threads about the same topic.
Hello gsharm3,
I tried your example, I tested it with your version and also the latest version of Net Advantage controls and do not see such behavior as the described. Yes, the performance is poor but please note that this WinGrid instance has a lot of rows and columns, therefore there are a lot of UIElements. They need to be painted everytime you scroll. I could not see any difference when scrolling up and scrolling down. Please take a look at the attached video file.
Thanks Boris.
It looks like the issue is not evident when the window is small.
Maximize the Window and try again.
You will see the scrolling up is substantially slower than scrolling down.
I still do not get this kind of behavior. Could you please provide a sample video of what you are describing as in issue.
Does this happen every time or only the first time?
In other words, if you scroll down once, then scroll back up to the top, and then scroll down again, is it faster the second time or is it still just as slow as the first time you scrolled down?
