Custom color not displaying [duplicate] - wpf

This question already has answers here:
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>

Style an activation indicator from material design

I want to style an activation indicator from material design in WPF. I want the styling to happen in an external styling.xaml file, so the textbox I'm using can be binded to that style.
The textbox:
<TextBox materialDesign:HintAssist.Hint="Search:" Grid.Column="1" Margin="35 8 20 5"
Width="200" Style="{"STYLE style"}/>
You could set it as a StaticResource:
File: styling.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:YourNamespace">
<Style TargetType="{x:Type TextBox}" x:key="YourCustomTextBoxStyle">
<Setter Property="Margin" Value="35 8 20 5"/>
....
</Style>
</ResourceDictionary>
In your View (or Application) add a reference to the styling ResourceDictionary and use the style as a static resource:
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:YourNamespace.Wpf"
x:Class="YourView" mc:Ignorable="d">
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/YourNamespace;component/Themes/styling.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
<TextBox materialDesign:HintAssist.Hint="Search:" Grid.Column="1" Width="200" Style="{StaticResource YourCustomTextBoxStyle}/>
</UserControl>

Resource dictionary cannot be found?

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
MainWindowStyles.xaml

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Reference external xaml styles from library to WPF Main app

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.
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Dictionaries/Buttons.xaml" />
</ResourceDictionary.MergedDictionaries>
Here is my usercontrol from Main vb.net app.
<UserControl x:Class="MyWF.UC"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:ms="clr-namespace:MyStyles;assembly=MyStyles" mc:Ignorable="d"
d:DesignHeight="100" d:DesignWidth="100">
<UserControl.Resources>
<ResourceDictionary

<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/MyStyles;component/General.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
<Grid>
<Button Style="{StaticResource MyButton}" />
</Grid>
This is my second try. Again failed with the same error according missing file.
<UserControl x:Class="MyWF.UC"

d:DesignHeight="100" d:DesignWidth="100">
<UserControl.Resources>
<ResourceDictionary

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/MyStyles;component/General.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
<Grid>
<Button Style="{StaticResource MyButton}" />
</Grid>
Error:
Additional information: 'Set property 'System.Windows.ResourceDictionary.Source' threw an exception.' Line number '27' and line position '18'.
{"Cannot locate resource 'general.xaml'."}
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>

Is it possible to reference a resource dictionary and define a style in the same resource section?

Like so:
<Window x:Class="WpfApplication3.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<ResourceDictionary x:Key=""whatever" Source="colors.xaml" />
<Style TargetType="Button">
<!- button style using colors defined in colors.xaml -->
</Style>
</Window.Resources>
<StackPanel>
<Button Background="{DynamicResource background1}" Height="50"></Button>
<Button Background="{DynamicResource background2}" Height="50"></Button>
</StackPanel>
</Window>
If I do that I get warnings about background1 and background2 not being resolved and an XamlParseException, because the Resource property of window is already defined (it is not). Everything is fine if I remove the stuff.
Any ideas?
It's easy with MergedDictionaries
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary x:Key=""whatever" Source="colors.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style TargetType="Button">
<!- button style using colors defined in colors.xaml -->
</Style>
</ResourceDictionary>
</Window.Resources>

WPF - MergedDictionary using RibbonControlsLibrary in xaml

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>
