Currently if the TreeView has deeper hierarchy or items with longer text, the end user will not be able to scroll horizontally.

When you have longer text shown in TreeView items and it is wrapped in 2 or 3 rows, the text is clipped incorrectly.

Please let us know:

  • Should the color be applied to the expand indicator as well, or should there be a separate property for this
  • Should the color be applied to the checkbox as well, or should there be a separate property for this

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

When you have custom ItemTemplates defined with different height, scrolling up through the items causes flickering, also you cannot scroll down to display all the items.

If items are loaded on demand and treeview is placed inside StackLayout, when collapsing and expanding items, at some point the rendering is messed up.

Trying to collapse an item after reinitialization of the RadTreeView causes the exception. The scenario can easily be recreated if all items from the ItemsSource are removed one by one and then added again then expand and collapse an item.

Calling TreeView's CheckItem method when the control is loaded, so that you mimic a "pre-checked" TreeView results in NullReferenceException in RadTreeView.Checkbox ToggleItem method.
