I have a TreeGrid with over 600,000 items.
At startup, scrolling performance is good, but when I add a subitem the performance decreases depending on the location of the parent item.
Anyone know why and how I can fix this?
In this GIF, only parent items are loaded and children are loaded on demand when the parent is expanded
Before asking this question, I suspected my code, after a scan of the application, 95% of the processors it uses by “native code” and I don’t know if this is from Eto or WPF
