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?
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.
