In my .Web MAUI app with CommunityToolkit.mvvm and CommunityToolkit.maui, I’ve an expander with a CollectionView in it:
<toolkit:Expander Margin="0,25">
<toolkit:Expander.Header>
<StackLayout Orientation="Horizontal">
<Label Textual content="{Binding LabelSelectTimeText}" FontFamily = "FontAwesome" Margin="0,0,25,0" VerticalTextAlignment="Heart" />
<Label Textual content="{Binding SelectedTimeDisplay, Mode=TwoWay, StringFormat="{0:hh:mm tt}"}" FontSize="Medium" VerticalTextAlignment="Heart" />
</StackLayout>
</toolkit:Expander.Header>
<CollectionView
SelectionChanged="CollectionView_SelectionChanged"
Margin="5,5,5,15"
ItemSizingStrategy="MeasureAllItems"
ItemsSource="{Binding Instances}"
SelectedItem="{Binding SelectedTime, Mode=TwoWay}"
SelectionMode="Single">
<CollectionView.ItemsLayout>
<GridItemsLayout Orientation="Vertical" Span="3" />
</CollectionView.ItemsLayout>
<CollectionView.ItemTemplate>
<DataTemplate>
<ContentView Padding="5" IsEnabled="{Binding IsAvailable}" >
<Border
StrokeThickness="1"
StrokeShape="RoundRectangle 10">
<Label
Textual content="{Binding Time, StringFormat="{0:hh:mm tt}"}"
Padding="10"
FontAttributes="Daring"
HorizontalTextAlignment="Heart"
BackgroundColor="{Binding IsAvailable, Converter={StaticResource BooleanToTimeColorConverter}}"
TextColor="Black" />
</Border>
</ContentView>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
</toolkit:Expander>
On Android it really works as anticipated, however on iOS the contents exhibits up when expanded first time, and after that no extra. When the expander is collapsed, after which expanded subsequent time, it’s empty. How can this be mounted?
