VirtualizingStackPanel not aligning menu items vertical on applying theme

Question

Before applying WPF theme - BureauBlue.xaml theme, I can see menu items aligning vertically with the below code:

<Menu.ItemsPanel>
    <ItemsPanelTemplate>
        <VirtualizingStackPanel Orientation="Vertical"/>
    </ItemsPanelTemplate>
</Menu.ItemsPanel>

But the same logic is aligning the menu items horizontally once I apply the theme.

Could you please assist me in resolving this?

Answer 1

I am able to solve the problem.

I am supposed to use VirtualizingStackPanel to display the menu items vertically.

In the theme style for Menu, StackPanel orientation is coded as Horizontal.

I just copied the code from the theme xaml and created a new style where the only change is Orientation from Horizontal to Vertical.

For the Menu, I have applied the new style as a DynamicResource.

It worked.

Thanks...
