Change Border MinimumHeightRequest from StaticRecourse depending Light or Dark Theme - collectionview

Question

In a CollectionView i use a Border with MinimumHeightRequest , trying to change the Height with StaticRecource depending on Dark or Light Theme.
Works with change the Stroke color or the Border but not the Height. Is this the wrong way or am i missing something.
In App.xaml the Style.
<Style x:Key="Nieuwslight" TargetType="Border">
<Setter Property="MinimumHeightRequest" Value="300" />
</Style>
<Style x:Key="NieuwsDark" TargetType="Border">
<Setter Property="MinimumHeightRequest" Value="220" />
</Style>
And the CollectionView with the Border
<CollectionView
x:Name="lstBal"
Grid.Row="1"
Grid.ColumnSpan="3"
BackgroundColor="{AppThemeBinding Light={StaticResource systemRed},
Dark={StaticResource Donkerrood}}"
ItemsSource="{Binding .}"
SelectionChanged="lstBal_SelectionChanged"
SelectionMode="Single">
<CollectionView.ItemsLayout>
<LinearItemsLayout ItemSpacing="20" Orientation="Vertical" />
</CollectionView.ItemsLayout>
<CollectionView.ItemTemplate>
<DataTemplate>
<Border x:Name="NieuwsBorder"
MinimumHeightRequest="{AppThemeBinding Light={StaticResource Nieuwslight},
Dark={StaticResource NieuwsDark}}"
Stroke="{AppThemeBinding Light={StaticResource LightBorderColor},
Dark={StaticResource Maroon}}"
StrokeShape=" RoundRectangle 10"
StrokeThickness="2">
<Grid Padding="15,0,0,0" ColumnDefinitions="*,2*">
<Frame
BackgroundColor="Transparent"
BorderColor="Transparent"
CornerRadius="15"
HeightRequest="150">
<Image
Aspect="AspectFill"
HeightRequest="150"
WidthRequest="120">
<Image.Source>
<UriImageSource
CacheValidity="5"
CachingEnabled="True"
Uri="{Binding Foto}" />
</Image.Source>
</Image>
</Frame>
<Label
Grid.Column="1"
Padding="25,5,5,0"
FontSize="22"
Text="{Binding Fototekst}"
TextColor="{AppThemeBinding Light={StaticResource DarkColor},
Dark={StaticResource LightTextColor}}" />
<Grid>
<Grid RowDefinitions="Auto,*,Auto" />
</Grid>
</Grid>
</Border>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>

Solved it .
In App.xaml set the Height for Minimum or Large.
<x:Double x:Key="defaultMinimumHeightRequest">220</x:Double>
<x:Double x:Key="largeMinimumHeightRequest">300</x:Double>
And in MainPage.xaml for the Border
<Border x:Name="NieuwsBorder"
MinimumHeightRequest="{AppThemeBinding Light={StaticResource defaultMinimumHeightRequest},
Dark={StaticResource largeMinimumHeightRequest}}"/>
