Set color from Code-Behind using Theme palette ?

Hello Romain,

You can access a color from the Telerik theme palette using the following syntax:

this.textBlock.Foreground = new SolidColorBrush(Windows11Palette.Palette.AccentColor);

However, using this approach the color won't change automatically on color variation change. In that case, you will need to manually re-set the Foreground (or whatever) property.

If you want to support a dynamic color change when the palette value gets changed (which is what happens on color variation change), you can use the Windows11Resource MarkupExtension. 

 <TextBlock Foreground="{telerik:Windows11Resource ResourceKey=AccentBrush}"/>

If you are using the Xaml version of the Telerik and the StyleManager for theming, then you will need also to merge the following resource in App.xaml. Otherwise, the dynamic change won't work.

<Application.Resources>
	<telerik:Windows11ResourceDictionary />
</Application.Resources>

However, keep in mind that, the WPF MarkupExtensions can be used only in XAML, therefore you cannot define that in C# code.

I hope that helps.

Thank you for your answer.

Is there an event triggered by some Theme related classes when the theme variation is changed ? I look in the Windows11Palette and didn't find one.

I could create my own event where I switch the variation but want to check if something similar already exists.

Thank you
