In code behind, this works:
this.Resources.MergedDictionaries.Add(Microsoft.Windows.Controls.Ribbon.PopularApplicationSkins.Office2007Black);
How do I do this in xaml?
Try the following:-
<Window x:Class="WPFRibbon.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:r="clr-namespace:Microsoft.Windows.Controls.Ribbon;assembly=RibbonControlsLibrary"
Title="Window1" Height="300" Width="400">
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/RibbonControlsLibrary;component/Themes/Office2007Black.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>

Defining a color in App.xaml and using as a static resource
(2 answers)
Closed 2 years ago.
I have a ResourceDictionary called MainTheme it looks like:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Color x:Key="BackgroundColor" R="35" G="35" B="35"></Color>
<Color x:Key="AccentColor" R="227" G="111" B="28"></Color>
<SolidColorBrush x:Key="BackgroundColorBrush" Color="{StaticResource BackgroundColor}"></SolidColorBrush>
<SolidColorBrush x:Key="AccentColorBrush" Color="{StaticResource AccentColor}"></SolidColorBrush>
</ResourceDictionary>
and I have a main window that looks like:
<Window x:Class="Elements.WindowsInstaller.Ui.Views.Shell"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:Elements.WindowsInstaller.Ui.Views"
mc:Ignorable="d"
Style="{StaticResource ShellStyle}"
Title="Shell" Height="450" Width="800">
<DockPanel>
<Border x:Name="Sidebar" DockPanel.Dock="Left" Width="65" Background="{DynamicResource AccentColorBrush}"></Border><!-- I have tried StaticResource and DynamicResource here -->
<ContentControl ></ContentControl>
</DockPanel>
</Window>
Then in the App.xaml I have this:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resources/MainTheme.xaml"></ResourceDictionary>
<ResourceDictionary Source="Resources/Window.xaml"></ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Can someone please tell me why the Sidebar isn't is not changing the background color?
I figured this out. The issue was the color that I set.
It should of been:
<Color x:Key="AccentColor" R="227" G="111" B="28" A="255"></Color>
could someone please help me to solve this problem, I think I have coded right the key required. This is a Style application dictionary test with just one Button. There are two error messages: Each dictionary entry must have an associated key, and All objects added to an IDictionary must have a Key attribute or some other type of key associated with them. Line 13 Position 14, both for MainWIndow.xaml.
There are no more code written by programmer in this project.
This is the MainWindow.xaml code:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary Source="App.xaml" /> This is the offending line
</ResourceDictionary>
</Window.Resources>
<Grid>
<Button Style="{StaticResource algo}" />
</Grid>
And this is the App.xaml code:
<Application x:Class="WpfApplication1.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1"
StartupUri="MainWindow.xaml">
<Application.Resources>
<Style x:Key="algo" TargetType="{x:Type Button}">
<Setter Property="Background" Value="Red" />
</Style>
</Application.Resources>
As pointed out in the comments, the syntax to reference a ResourceDictionary is
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="myresourcedictionary.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
Direct content of ResourceDictionary is considered to be the dictionary's entries. This is where the missing Key error refers to. A dictionary should have look up Keys for all its entries:
<Window.Resources>
<ResourceDictionary>
<conv:BoolToVisibilityConverter x:Key="BoolToVisibilityConverter" />
<conv:BoolToCollapsedConverter x:Key="BoolToCollapsedConverter" />
...
</ResourceDictionary>
</Window.Resources>
An exception to the rule are implicit Styles (Styles that have a TargetType instead of a Key).
In your case none of the above will help, since Resources in App.xaml are treated special. They're considered Global Resources and can be referenced from everywhere. Trying to do reference them explicitly as in the first example will result in
An error occurred while finding the resource dictionary "App.xaml".
Instead change your MainWindow.xaml to
<Window x:Class="WpfApplication1.MainWindow"
...
Title="MainWindow" Height="350" Width="525">
<Grid>
<Button Style="{StaticResource algo}" />
</Grid>
Thank you Funk, thank you Mathew Jibin, your explanations lead me to find what I think is the solution, it is as follows:
Modified App.xaml to be like this:
<Application.Resources>
<Style TargetType="Button">
<Setter Property="Background" Value="Red" />
</Style>
</Application.Resources>
And modified MainWindow deleting everything in Grid:
...
Title="MainWindow" Height="350" Width="525">
<Grid>
</Grid>
Now, everytime I create a new button it has the desired Style. Please let me know if you see any possible problem with this solution. Thanks.
Background
I am attempting to build an app in WPF using Mahapps Metro for the very first time. I have followed all of the steps in the Mahapps Quick Start guide here, yet my results look completely different (shown below):
I'm not exactly sure what else I should try. My XAML files are exactly the same as the examples.
Here is what my App.xaml file looks like:
<Application x:Class="RxExample.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:RxExample"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<!-- MahApps.Metro resource dictionaries. Make sure that all file names are Case Sensitive! -->
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<!-- Accent and AppTheme setting -->
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Here is what my MainWindow.xaml file looks like:
<Window x:Class="RxExample.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:RxExample"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="368*"/>
<ColumnDefinition Width="149*"/>
</Grid.ColumnDefinitions>
</Grid>
Question
What may be the issue here, or is it Mahapps?
Try adding the following to your App.xaml file:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
Also make sure you change in your MainWindow.xaml:
Window x:Class... for <Controls:MetroWindow x:Class..`
and changing Baseclass in your MainWindow.xaml.cs, instead of MainWindow : Window it must be MainWindow : MetroWindow
At least I think this is the problem...
I have a project structured like so (files omitted for brevity)
Project
Assets
ResourceDictionaries
Styles.xaml
MainWindow.xaml
I am referencing the resource dictionary as follows in MainWindow.xaml
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Assets/ResourceDictionaries/Styles.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
<Window.Resources/>
But none of the styles are being applied to any elements.
I've checked the Build Action is set to page. I've also tried giving some styles in the dictionary a key, but Blend cannot 'see' these keys.
What am I doing wrong?
Edit: Relevant code. Obviously if I put the properties on the actual elements they work, but in a dictionary they don't:
MainWindowStyles.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Company.Client.Assets.ResourceDictionaries"
xmlns:wpf="http://schemas.syncfusion.com/wpf">
<Style TargetType="{x:Type wpf:RibbonWindow}">
<Setter Property="wpf:SkinStorage.VisualStyle" Value="Office2010Silver"/>
</Style>
<Style TargetType="{x:Type wpf:Ribbon}">
<Setter Property="BackStageColor" Value="#622166"/>
</Style>
</ResourceDictionary>
MainWindow.xaml
<wpf:RibbonWindow x:Class="Company.Client.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:wpf="http://schemas.syncfusion.com/wpf"
xmlns:local="clr-namespace:Company.Client"
mc:Ignorable="d"
Title="MainWindow" Height="600" Width="800">
<wpf:RibbonWindow.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Assets/ResourceDictionaries/MainWindowStyles.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</wpf:RibbonWindow.Resources>
<Grid>
<wpf:Ribbon BackStageHeader="DB">
<wpf:Ribbon.BackStage>
<wpf:Backstage>
<wpf:BackStageCommandButton Header="Save"/>
</wpf:Backstage>
</wpf:Ribbon.BackStage>
</wpf:Ribbon>
</Grid>
</wpf:RibbonWindow>
Edit 2:
This is what has been tried so far:
Tried applying styles to normal controls (Button, Label, etc.). Works
Tried adding the styles under <wpf:MainWindow.Resources>. Doesn't work
Tried a pack URI. Doesn't work
Adding the styles/properties to the actual elements. Works (obviously)
Have you tried these two steps:
Add MainWindowStyles.xaml to Application.Resources section in app.xaml
Use explicit style for RibbonWindow, like this:
<RibbonWindow>
...
<RibbonWindow.Style>
<StaticResource ResourceKey="RadRibbonWindowStyle"/>
<RibbonWindow.Style>
Use the pack URI syntax:
<ResourceDictionary Source="pack://application:,,,/Assets/ResourceDictionaries/Styles.xaml"/>
Adding this to supplement the accepted answer.
My code now looks like this. I didn't manage to get it to work with the VisualStyle property, but this will do. If anyone does know how to get that into a Resource Dictionary though, the help would be much appreciated. :)
Long story short, this is the code that works based on the exchange between me and #AlexSeleznyov

I have one Main App.exe WPF on VB.NET. Application have one library C#.NET.
App reference project library.
I try to get style from external library but give error.
This is my "Sharp.LIB" project: "Dictionaries/Buttons.xaml"
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style TargetType="Button" x:Key="MyButton">
<Setter Property="Background" Value="Green" />
<Setter Property="Width" Value="100" />
<Setter Property="Height" Value="40" />
<Setter Property="Content" Value="Hello from style" />
</Style>
This is my second file "General.xaml" to marge all styles. At now I merge only one Buttons styles.

PLEASE HELP.
As this question is unsolved till now: The pack URI should look like this:
<ResourceDictionary Source="pack://application:,,,/$assemblyName$;component/$folder$/Style.xaml"/>
see Resource File Pack URIs:
The following example shows the pack URI for a XAML resource file that is located in a subfolder of the referenced assembly's project folder.
pack://application:,,,/ReferencedAssembly;component/Subfolder/ResourceFile.xaml
e.g.
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/WPF.Controls;component/Templates/Style.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
