I have a windows 8.1 app.
In Project.Shared there is ResourceDictionary SharedResources.xaml with base style,
<Style x:Key="CommonLayerListItemStyle" TargetType="TextBlock">
<Setter Property="FontFamily" Value="Segoe WP" />
<Setter Property="Foreground" Value="{StaticResource UnselectBrush}" />
<Setter Property="VerticalAlignment" Value="Stretch" />
</Style>
in Windows Phone app is StyleResources.xaml wiht style based on this
<Style x:Key="LayerListItemStyle"
BasedOn="{StaticResource CommonLayerListItemStyle}"
TargetType="TextBlock">
<Setter Property="FontSize" Value="20" />
</Style>
same in Windows app StyleResources.xaml:
<Style x:Key="LayerListItemStyle"
BasedOn="{StaticResource CommonLayerListItemStyle}"
TargetType="TextBlock">
<Setter Property="FontSize" Value="28" />
<Setter Property="Margin" Value="42,0,0,0" />
</Style>
All styles are used in UserControl created in Shared project.
I do this to override FontSize on diffrent platforms.
I merged all dictionaries in App.xaml
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles/SharedResources.xaml" />
<ResourceDictionary Source="Styles/StyleResources.xaml" />
</ResourceDictionary.MergedDictionaries>
But my app does not start with Unhandled exception
Cannot find a Resource with the Name/Key CommonLayerListItemStyle [Line: 10 Position: 37]
Why does this happens?
I had the same issue. You need to merge the SharedResources.xaml directly into StyleResources.xaml, and only reference StyleResources.xaml from App.xaml.
Here is a complete example:

somebody knows how to change the bar color, that I point out in the image
bar flyout
If you want to change the background color of Navigation Bar in shell , we could set the style of Shell navigation bar in Resource Dictionary .
<Shell.Resources>
<ResourceDictionary>
<Color x:Key="NavigationPrimary">#2196F3</Color>
<Style x:Key="BaseStyle" TargetType="Element">
<Setter Property="Shell.BackgroundColor" Value="Red" /> // set navigation bar color here
<Setter Property="Shell.ForegroundColor" Value="Blue" />
<Setter Property="Shell.TitleColor" Value="Blue" />
<Setter Property="Shell.DisabledColor" Value="#B4FFFFFF" />
<Setter Property="Shell.UnselectedColor" Value="#95FFFFFF" />
<Setter Property="Shell.TabBarBackgroundColor" Value="{StaticResource NavigationPrimary}" />
<Setter Property="Shell.TabBarForegroundColor" Value="White"/>
<Setter Property="Shell.TabBarUnselectedColor" Value="#95FFFFFF"/>
<Setter Property="Shell.TabBarTitleColor" Value="White"/>
</Style>
<Style TargetType="TabBar" BasedOn="{StaticResource BaseStyle}" />
</ResourceDictionary>
</Shell.Resources>
For NavigationPage (I assume your detail page is composed of a NavigationPage and inside your HomePage or CurrentNavigatedPageFromMenu, here is a simple style :
<Style x:Key="NavigationPageStyle" TargetType="NavigationPage">
<Setter Property="BarBackgroundColor" Value="Red" />
<Setter Property="BarTextColor" Value="White" />
</Style>
<Style BasedOn="{StaticResource NavigationPageStyle}" TargetType="NavigationPage" />
I separate them to allow to reuse the style on other Navigation page control I've extended.
In code behind, in the constructor of your page (can be usefull to provide a different color depend on the page you are, exemple : red for error page, green for parameter, blue for others).
((NavigationPage)Application.Current.MainPage).BarBackgroundColor = Color.Red;
((NavigationPage)Application.Current.MainPage).BarTextColor = Color.White;
You can find some usefull tips [Xamarin Forum too][1].
Don't ask me why, but I thought only <ContentPage> can have <ContentPage.Resources>.
So I had a bunch of color setters and what not in almost every XAML page like this:
<ContentPage.Resources>
<Style TargetType="NavigationPage">
<Setter Property="BarBackgroundColor" Value="#000" />
<Setter Property="BarTextColor" Value="#20b8a2" />
</Style>
<Style TargetType="ContentPage">
<Setter Property="BackgroundColor" Value="#231f20" />
</Style>
<Style TargetType="Label">
<Setter Property="TextColor" Value="#f7f7f7" />
</Style>
<Style TargetType="Entry">
<Setter Property="TextColor" Value="#f7f7f7" />
</Style>
<Style TargetType="Button">
<Setter Property="BackgroundColor" Value="#0089c1" />
<Setter Property="TextColor" Value="#f7f7f7" />
<Setter Property="CornerRadius" Value="0" />
</Style>
</ContentPage.Resources>
So how to change all main colors in one place?
So instead of having resources in every Solution/App/Views/SubPage.xaml file there is obviously an outermost XAML file in general projects root Solution/App/App.xaml where you can simply set these resources for entire application.
<Application ...>
<Application.Resources>
<Color x:Key="PrimaryColor">#20b8a2</Color> <!-- turqoise -->
<Color x:Key="SecondaryColor">#0089c1</Color> <!-- blue -->
<Color x:Key="TertiaryColor">#ef569f</Color> <!-- pink -->
<Color x:Key="ThemeExtremeColor">#000000</Color>
<Color x:Key="ThemeMainColor">#231f20</Color>
<Color x:Key="ThemeLighterColor">#333333</Color>
<Color x:Key="TextColor">#f7f7f7</Color>
<Style TargetType="NavigationPage">
<Setter Property="BarBackgroundColor" Value="{StaticResource ThemeExtremeColor}" />
<Setter Property="BarTextColor" Value="{StaticResource PrimaryColor}" />
</Style>
<Style TargetType="ContentPage">
<Setter Property="BackgroundColor" Value="{StaticResource ThemeMainColor}" />
</Style>
<Style TargetType="Grid">
<Setter Property="BackgroundColor" Value="{StaticResource ThemeMainColor}" />
</Style>
<!--<Style TargetType="ListView">
<Setter Property="BackgroundColor" Value="{StaticResource ThemeMainColor}" />
</Style>-->
<Style TargetType="Label">
<Setter Property="TextColor" Value="{StaticResource TextColor}" />
</Style>
<Style TargetType="Entry">
<Setter Property="TextColor" Value="{StaticResource TextColor}" />
</Style>
<Style TargetType="Button">
<Setter Property="BackgroundColor" Value="{StaticResource SecondaryColor}" />
<Setter Property="TextColor" Value="{StaticResource TextColor}" />
<Setter Property="CornerRadius" Value="0" />
</Style>
</Application.Resources>
....
</Application>
Now "{StaticResource TextColor}" can be used anywhere in XAML.
I have a UWP App. The Styles works without a problem when I execute the app. But not in the Designer. Especially User Control can't be loaded. The Error message who is displayed is:
Cannot find a Resource with the Name / Key [Name]
When I go to that User Control it mostly is displayed correctly.
I reference the style with:
Style="{StaticResource DeemphasizedBodyTextBlockStyle}"
I have a file for my Textstyles. In that file I have the style defined as followed:
<Style x:Key="DeemphasizedBodyTextBlockStyle"
TargetType="TextBlock"
BasedOn="{StaticResource BodyTextBlockStyle}">
<Setter Property="FontSize"
Value="12" />
<Setter Property="TextWrapping"
Value="NoWrap" />
<Setter Property="CharacterSpacing"
Value="75" />
<Setter Property="HorizontalAlignment"
Value="Left" />
<Setter Property="VerticalAlignment"
Value="Top" />
<Setter Property="Foreground"
Value="{StaticResource AppForegroundColorSecondary}" />
</Style>
And in the properties of the view project I have a Designer Resource file added (as page) with the following content:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ms-appx:///Style/AppStyles.xaml" />
<ResourceDictionary Source="ms-appx:///Style/ColorsDark.xaml" />
<ResourceDictionary Source="ms-appx:///Style/ColorsLight.xaml" />
<ResourceDictionary Source="ms-appx:///Style/ControlStyles.xaml" />
<ResourceDictionary Source="ms-appx:///Style/TextStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

My styles are separated in separate files for better organization and readability. All files are referenced in my App.xaml. Some styles are BasedOn other styles, so I have placed them in the proper order so that the inherited styles are loaded before the dependent ones. However, I am still getting the following error on my XAML views that reference a font style, for example...Cannot find a Resource with the Name/Key SourceSansPro-Light.
Can someone enlighten me on why this Name/Key cannot be found? Here's the relevant code.
App.xaml
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Common/Styles/StyleResources.xaml" />
<ResourceDictionary Source="Common/Styles/InputStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
StyleResources.xaml
<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Light">
<SolidColorBrush x:Key="TextBoxBackgroundBrush" Color="White"/>
</ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>
<FontFamily x:Key="SourceSansPro-Light">../../Assets/Fonts/SourceSansPro-Light.otf#Source Sans Pro</FontFamily>
<Style x:Key="TextBlockStyle" TargetType="TextBlock" BasedOn="{StaticResource BaseTextBlockStyle}">
<Setter Property="FontSize" Value="18"/>
<Setter Property="FontFamily" Value="{StaticResource SourceSansPro-Semibold}" />
</Style>
InputStyles.xaml
<Style x:Key="SecondaryTextStyle" TargetType="TextBlock" BasedOn="{StaticResource TextBlockStyle}">
<Setter Property="FontFamily" Value="{StaticResource SourceSansPro-Light}"/>
</Style>
HomePage.xaml (where style, SourceSansPro-Light, is being called in this view)
<Page.Resources>
<Style x:Name="InfoBodyTextStyle" TargetType="TextBlock">
<Setter Property="FontFamily" Value="{StaticResource SourceSansPro-Light}"/>
</Style>
Please try this code.
<Style TargetType="TextBlock">
<Setter Property="Foreground" Value="#FF64CCEF"/>
<Setter Property="SnapsToDevicePixels" Value="True"/>
<Setter Property="FontFamily" Value="{DynamicResource FontFamilyResource}"/>
</Style>
<FontFamily x:Key="FontFamilyResource">/ApplicationName(SolutionName);component/Resources/Fonts/#Vladimir Script</FontFamily>
In Windows 8, you were able to create your own themes for your application (here's a tutorial).
In Windows 8.1 Applications, themes are handled differently: you can change them at run-time and set a theme for a specific control in your XAML (if you don't want to apply the theme to the whole Application).
For instance:
<Grid x:Name="MainGrid" RequestedTheme="Dark">
However, I could not find a way to create my own themes. The property RequestedTheme takes an enumeration (its type is FrameworkElement.RequestedTheme) and an enumeration by definition cannot be extended (in C#). Also, if I want to define a new Theme Dictionary I would have written:
<ResourceDictionary.ThemeDictionaries>
But it is not available in Windows 8.1.
How can one create a theme in Windows 8.1? Am I limited to the existing ones (light & dark)?
Yes you're restricted to 3 themes I believe
Default (light)
Dark
High Contrast
You can create new styles or override existing ones for the 3 themes like this in 8.1
<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Default">
<Style TargetType="TextBlock">
<Setter Property="FontSize" Value="24" />
<Setter Property="Foreground" Value="Green"/>
</Style>
</ResourceDictionary>
<ResourceDictionary x:Key="Dark">
<Style TargetType="TextBlock">
<Setter Property="FontSize" Value="30" />
<Setter Property="Foreground" Value="Orange"/>
</Style>
</ResourceDictionary>
<ResourceDictionary x:Key="HighContrast">
<Style TargetType="TextBlock">
<Setter Property="FontSize" Value="24" />
<Setter Property="Foreground" Value="Blue"/>
</Style>
</ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>
