SatsuiUi is a library containing a skin system and several controls i created for my own WPF projects.
You can change the theme on the fly.
It's easy, fast to use and free.

The Nuget package is available here : https://www.nuget.org/packages/Messatsu.SatsuiUi/

PM> Install-Package Messatsu.SatsuiUi

When the Nuget package is installed, instantiate a SkinManager object which take your application resources as parameter :

SkinManager manager = new SkinManager(Application.Current.Resources);

Then select a default skin and a color :

manager.SetCurrentSkin(manager.Skins[0], 1);

In your XAML code, add a reference to SatsuiUi.Controls

xmlns:ctrls="clr-namespace:SatsuiUi.Controls;assembly=SatsuiUi"

For now, there is 2 differents skins and 2 differents colors for each one :

• (0) Crystal :
  • (1) Light
  • (2) Dark
• (1) Classic :
  • (1) White
  • (2) Black

• SatsuiWindow (improved window)
• Button
• HintTextBox (improved TextBox)
• HintComboBox (improved ComboBox)
• CheckBox
• ProgressBar
• Slider
• ListBox
• ListView
• ContentControl
• HintGroupBox (improved GroupBox)
• ColorPicker
• ImagePicker
• SoundPicker
• FontPicker
• KeyPicker
• ContributorsList

You can add your owns controls to a skin using the AddResource function :

// Add a custom template to the Crystal skin 
manager.addResource(manager.Skins[0], "/YourProject;component/Path/YourTemplateResource.xaml");

// Add colors definitions for the Light color of the Crystal skin
manager.AddResource(manager.Skins[0], 1, "/YourProject;component/Path/YourFirstColorsResource.xaml");

// Add colors definitions for the Dark color of the Crystal skin
manager.AddResource(manager.Skins[0], 1, "/YourProject;component/Path/YourSecondColorsResource.xaml");

There is an example in the DemoMVVM project, feel free to ask me if you got any problem.

All customs controls are designed to support translation.
For example, you can change default texts of a ImagePicker control :

<ctrls:ImagePicker 
	NoFileText="No file selected"
	ValidText="Let's go !"
	RemoveText="Remove this !"
	BrowseText="Let's pick some cool images"
	DialogTitle="Im a beautiful window !"/>
