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.

when custom renderer is registered, it is not applied to the TreeView control. The default one overrides the custom one.

If there is an input control (Editor, Entry) inside the ItemTemplate of the TreeViewDescriptor and its Text is bound to any property of the data item, changing the ItemsSource of the TreeView raises an exception of type AccessViolationException.

Release R3 2019
When the custom ItemTemplate sets bigger value of its Height e.g. more than 44 pixels, the content of the UITreeViewCell is not sized correctly. Only the cell gets the correct value.

When using MvvmCross framework to load data when the View appears on the screen the ListView cannot be scrolled. It starts jumping rapidly instead.

Workaround:
Load the data in the constructor of the respective ViewModel instead inside its ViewAppearing() method.

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

Provide an option to allow the checkbox to be rendered to the right of the node's content. 

 

A mock code example:

<RadTreeView CheckBoxHorizontalOptions="End" />

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.

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

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.
