Picker used in Popup not inheriting color brushes

Question

Hello,

I'm styling my Pickers as described in one comment here:

https://github.com/dotnet/maui/issues/13418

    <maui:MauiWinUIApplication.Resources>
        <SolidColorBrush x:Key="ComboBoxItemForegroundPointerOver" Color="#00FF00" /> 
        <SolidColorBrush x:Key="ComboBoxDropDownBackground" Color="#444444" />
        <SolidColorBrush x:Key="ComboBoxItemForeground" Color="#FFFFFF" />
        <SolidColorBrush x:Key="ComboBoxForegroundPointerOver" Color="#FFFFFF" />
        <SolidColorBrush x:Key="ComboBoxItemForegroundSelected" Color="#FFFFFF" />
        <SolidColorBrush x:Key="ComboBoxItemForegroundSelectedPointerOver" Color="#00FF00" />
        <SolidColorBrush x:Key="ComboBoxItemForegroundPressed" Color="#FF00FF" />
        <SolidColorBrush x:Key="ComboBoxForegroundPressed" Color="#FFFFFF" />
        <SolidColorBrush x:Key="ComboBoxItemForegroundSelectedPressed" Color="#00FF00" />
        <SolidColorBrush x:Key="ComboBoxItemBackgroundSelected" Color="#777777" />
        <SolidColorBrush x:Key="ComboBoxItemBackgroundSelectedPointerOver" Color="#777777" />
        <SolidColorBrush x:Key="ComboBoxItemBackgroundSelectedPressed" Color="#777777" />
    </maui:MauiWinUIApplication.Resources>

This approach correctly styles my pickers when used in a ContentPage. However, if I use a picker in a toolkit:Popup, it does not style the picker correctly. I tried setting the color brushes directly to the popup resources, but it did not work. The described behavior can be reproduced with this repository:

https://github.com/nuxosio/maui-pickers-popup

If you check in my reproduction repository, you will see a picker in the MainPage with a green color while hovering. If you open the popup, the same picker is there, but the green color is not seen anymore.

I hope someone can give me some ideas for solving this issue.

Hello,

Thanks for your feedback.

ToolKit:Popup corresponds to the Microsoft.UI.Xaml.Controls.Primitives.Popup control in WinUI3, and after testing, this issue does not occur in WinUI3 native Popup. Therefore, this issue should be specific to ToolKit:Pupop.

For this issue, it is recommended that you report it to the official Toolkit repository to make the development team aware of it.

Best Regards,

Alec Liu.
