Question

I am building a Maui App and i have noticed that on Windows , when i wrap a picker inside a Frame element , the selected item disappears. Has anyone encountered the same issue and found a workaround ? or am i doing somenthing wrong?

I have created a very simple example , the upper picker works properly , while the 2nd is showing this issue. https://streamable.com/v16niw

    <Grid
        RowDefinitions="*,*">

        <Picker
            Grid.Column="0"
            Grid.Row="0"
            x:Name="Monkey"
            HorizontalOptions="Center"
            HorizontalTextAlignment="Center"
            FontAttributes="Bold">
            <Picker.Items>
                <x:String>Baboon</x:String>
                <x:String>Capuchin Monkey</x:String>
                <x:String>Blue Monkey</x:String>
                <x:String>Squirrel Monkey</x:String>

当一把一个小块元素中一个小小小小块块的 pick子包裹时,选定项目消失。

我测试了你提供的代码,发现你在第二批“白”的采集器中设置了<代码>TextColor。我把它定在“黑色”上,这样它就会很好地发挥作用。
