Scrolling a TreeView with expandable items on iOS causes items to randomly change position in the control and prevent items from being selected.
This renders the control unusable on iOS when expandable items are present.
I've attached a basic project that demonstrates the issue.
The project just needs the latest Telerik binaries added to it. They were too large to include.
I believe this is the same issue Martin was experiencing in the comments of https://feedback.telerik.com/xamarin/1427193-treeview-ios-wrong-visualization-with-custom-itemtemplate
Please let us know:
Currently this could be accomplished through methods.
When CollapseAll method is called, if the first element is out of the screen (after a scroll), the treeview crashes. Available in minor release 2018.3.1109. It will also be available in the R1 2019 release.
