Native Control Themes

Control themes are included for all native Avalonia controls that share the same design aesthetic as Actipro's own controls, allowing all controls to seamlessly mix within an application. The native control themes are enabled by default, and many support a variety of design options, along with semantic color variants.

Native Controls

Nearly all native Avalonia controls have control themes in the ActiproSoftware.Controls.Avalonia NuGet package. The only exceptions are the native ColorPicker and DataGrid controls since they are shipped by the Avalonia team in separate optional NuGet packages of their own.

Configuring

As described in the Getting Started topic, when adding a ModernTheme instance to the Application.Styles collection, native control themes will be enabled by default. They can be disabled by setting the AreNativeControlThemesEnabled property to false.

This example of adding ModernTheme to the Application.Styles collection automatically enables native control themes.

<Application ... xmlns:actipro="http://schemas.actiprosoftware.com/avaloniaui">
	<Application.Styles>

		<actipro:ModernTheme />

	</Application.Styles>
</Application>

Several theme definition options allow for selection of which control theme to use by default. The following example shows how to tell the theme to render tabs using a Subtle appearance instead of Outline.

<Application ...
	xmlns:actipro="http://schemas.actiprosoftware.com/avaloniaui"
	xmlns:generation="using:ActiproSoftware.UI.Avalonia.Themes.Generation">
	<Application.Styles>

		<actipro:ModernTheme>
			<actipro:ModernTheme.Definition>
				<generator:ThemeDefinition TabAppearanceKind="Subtle" />
			</actipro:ModernTheme.Definition>
		</actipro:ModernTheme>

	</Application.Styles>
</Application>

Color Variants

Screenshot

Most native controls support multiple semantic color variants. Use one of the following style class names to alter the semantic color variant of supported controls:

accent - Uses the theme's accent color ramp, which defaults to blue.
success - Uses the theme's success color ramp, which defaults to green.
warning - Uses the theme's warning color ramp, which defaults to orange.
danger - Uses the theme's danger color ramp, which defaults to red.

Control Theme Kinds

The ControlThemeKind enumeration has a value for all controls supported by Actipro's themes, including many native control themes.

Tip

See the Theme Assets topic for information on how to reference and use specific control themes, which is important when a control should have a non-default theme (e.g., a Solid button instead of an Outline button in a certain scenario), or when making a custom control theme that should be based on one of the Actipro control themes.

The lists below show the various control theme kind options for each type, and in parentheses indicate any style class names that can be specified to trigger the control theme.

This example shows how to render a solid accented button:

<Button Classes="theme-solid accent" Content="Accented Solid Button" />

Then as described in the Getting Started topic, the ModernTheme.Includes property must specify either the NativeColorPicker or All option, as in the following example.

<Application ... xmlns:actipro="http://schemas.actiprosoftware.com/avaloniaui">
