RootCause

ListViewRenderer Crash on HostApp

As the HostApp uses a ListView to display a list of items, selecting a page navigates to the corresponding test cases and sets the sample page as the current main page. This action disposes the HostApp's main page, which contains the ListView. As a result, the previous list is also disposed, leading to a crash in the ListViewRenderer during the OnControlSelectionChanged event.

BindingErrors occurs on windows platform

In the HostApp, the pages private field of the ListView is set as the BindingContext of the ListView, which is causing the issue. The pages field is directly assigned to the ItemsSource, so there's no need to set the BindingContext. The problem arises because the same collection is being used for both the BindingContext and the ItemsSource, which is the root cause of the issue.

Description of Change

Ensuring that Element is not null before updating the selection will resolve the issue

BindingErrors occurs on windows platform

There is no need to define the BindingContext.
