Question

I am trying to define a standard foreground color for the controls in my page. However, I get the error “An object of the type “System.String” cannot be applied to a property that expects the type “Windows.UI.Xaml.Media.Brush”.

In myPage.xaml

<TextBlock TextWrapping="Wrap" 
           Foreground="{StaticResource ForegroundThemeBrush}" />

In StandardStyles.xaml

<ResourceDictionary x:Key="Default">

  <x:String x:Key="BackgroundThemeBrush">#484848</x:String>
  <x:String x:Key="ForegroundThemeBrush">#efefef</x:String>

</ResourceDictionary>

Answer 1

you need to define SolidColorBrush not x:String

<ResourceDictionary x:Key="Default">
  <SolidColorBrush x:Key="BackgroundThemeBrush" Color="#484848"/>
  <SolidColorBrush x:Key="ForegroundThemeBrush" Color="#efefef"/>
</ResourceDictionary>
