Mam okno z poniższym XAML:Dlaczego kolejność kart między/wewnątrz widoku drzewa nie działa?
<Window x:Class="TestDemoApp.TreeViewWindow"

<ListView TabIndex="1" BorderThickness="5" Focusable="True" IsTabStop="True" KeyboardNavigation.TabNavigation="Continue" FocusVisualStyle="{StaticResource FocusedStyle}">
<ListViewItem TabIndex="2" Content="List Item 1"/>
<ListViewItem TabIndex="3" Content="List Item 2"/>
</ListView>
<TreeView TabIndex="6" BorderThickness="5" Focusable="True" IsTabStop="True" KeyboardNavigation.TabNavigation="Continue" Grid.Row="1" FocusVisualStyle="{StaticResource FocusedStyle}">
<TreeView.Items>
<TreeViewItem TabIndex="7" Header="Tree Item 1">
<TreeViewItem Header="Tree Item 11"></TreeViewItem>
<TreeViewItem Header="Tree Item 12"/>
</TreeViewItem>
<TreeViewItem Header="Tree Item 2">
</TreeViewItem>
</TreeView.Items>
</TreeView>
</Grid>
</Window>
Kiedy uruchamiam program, kolejność karta jest:
1. List View 2. List Item 1 3. List Item 2 4. Tree View 5. Tree Item 1 6. Tree Item 2 7. List View (#1) 8. List Item 1 (#2) 9. List Item 2 (#3) 10. Tree Item 2 (6#) 11+ Repeat #7 - #10
Oczekiwane zachowanie jest, że to powtarza się od # 1 do # 6 na kolejne iteracje, zamiast tego pomija # 4 i # 5 w kolejnych iteracjach.
Dlaczego tak jest? I jak mogę to naprawić?
