Describe the bug
The following TreeView causes a crash
<TreeView
SelectionMode="Multiple"
ItemsSource="{x:Bind TreeViewItems}">
<TreeView.ItemTemplate>
<DataTemplate x:DataType="local:TreeNode">
<TreeViewItem Visibility="Collapsed"/>
</DataTemplate>
</TreeView.ItemTemplate>
</TreeView>
Steps to reproduce the bug
- Clone the example at https://github.com/alataffective/WinUI3TreeViewCrash
- Run the example
The application crashes.
This appears to be due to the combination of TreeView SelectionMode="Multiple" and TreeViewItem Visibility="Collapsed". Changing the TreeViewItem Visibility="Visible" or the TreeView SelectionMode to another value, the application no longer crashes.
Expected behavior
The application should not crash.
