VisualStudio2019 Theme

With the R3 2019 release of the UI for WPF suite we have introduced the brand new VisualStudio2019 theme. Inspired by the new refreshed Visual Studio 2019 IDE, the VisualStudio2019 theme delivers a lot cleaner and smoother look and feel to your WPF apps. The team at Microsoft are well known for their eagerness to deliver the best possible user experience that we encounter every day and with the VisualStudio2019 theme you will be able to easily bring it to your own apps.

With the R2 2021 release of the UI for WPF suite, we have designed and delivered a brand new color variation of the VisualStudio2019 theme - the Dark one. In addition to it, the theme palette expanded its brushes collection with the AccentForegroundBrush and the DockingBackgroundBrush, which are available for both color variations.

The following topic explains the specifics of the theme's palette and features.

Special Brushes

The AccentFocusedBrush and the DockingBackgroundBrush are not available with versions prior to the R2 2021 release of the UI for WPF suite.

Other Properties

  • DisabledOpacity: Used for controls when they are in a disabled state. Backgrounds usually use the ComplementaryBrush when disabled.
  • ReadOnlyOpacity: Used for controls when they are in a read-only state.

Theme Variation Changing

Since the R2 2021 release of the UI for WPF suite the VisualStudio2019 theme offers two color variations. The Blue variation corresponds to the Visual Studio 2019 IDE's Blue theme, and the Dark - to the Dark theme. The following example demonstrates the ability to switch between the supported Blue and Dark color palettes by calling the LoadPreset() method as shown below:

Example 1: Changing the color variation of the theme

//default color variation  
VisualStudio2019Palette.LoadPreset(VisualStudio2019Palette.ColorVariation.Blue);    
 
//Dark color variation  
VisualStudio2019Palette.LoadPreset(VisualStudio2019Palette.ColorVariation.Dark);

Font Family and Font Size

When using the VisualStudio2019 theme you can dynamically change the FontSize and FontFamily properties of all components in the application the same way as you do in Windows8, Windows8Touch, Office2013, VisualStudio2013, Office2016, Green, Material, Fluent and Crystal themes.

The FontSize and FontFamily properties are public so you can easily modify the theme resources at a single point. The most commonly used font size in the theme is with value 12 and can be modified through the VisualStudio2019Palette.Palette.FontSize property in the same manner as in the other themes that support a theme palette.

The default font used in the theme is Segoe UI.

For complex scenarios we strongly recommend setting the FontSize properties only before the application is initialized.

Example 2 shows the default font sizes and families.

Example 2: Default FontSize

VisualStudio2019Palette.Palette.FontSizeXS = 10; 
VisualStudio2019Palette.Palette.FontSizeS = 11; 
VisualStudio2019Palette.Palette.FontSize = 12; 
VisualStudio2019Palette.Palette.FontSizeL = 13; 
VisualStudio2019Palette.Palette.FontSizeXL = 20;
Example 3 shows how to change the default FontFamily from "Segoe UI" to "Calibri Italic" and the FontSize from 12 to 16.

Example 3: Changing the theme's FontSize and FontFamily

private void OnButtonChangeFontSizeClick(object sender, RoutedEventArgs e) 
{ 
    VisualStudio2019Palette.Palette.FontSize = 16; 
    VisualStudio2019Palette.Palette.FontFamily = new FontFamily("Calibri Italic"); 
}

Glyphs

The VisualStudio2019 Theme also uses the Telerik Web UI font glyphs by default. The RadGlyph provides a lightweight, flexible and design-time-friendly implementation of our glyph font.

You can read more about the RadGlyph in the RadGlyph Overview article and about the range of the font glyphs in the Font Glyphs Overview article.

Theme Helper

The ThemeHelper class that comes with the R3 2019 release is used in the VisualStudio2019 theme. It exposes a set of attached properties and can be used to directly modify the appearance of a specific basic control without the need to alter its control template.

Example 4 shows a RadToggleButton control with modified brushes for its different states through the ThemeHelper class:

Example 4: Set RadToggleButton's visual appearance through the ThemeHelper class

<telerik:RadToggleButton Content="RadButton"  
                         Margin="10" 
                         xmlns:helpers="clr-namespace:Telerik.Windows.Controls.Theming.Helpers;assembly=Telerik.Windows.Controls" 
                         helpers:ThemeHelper.MouseOverBrush="{telerik:VisualStudio2019Resource ResourceKey=AccentMouseOverBrush}" 
                         helpers:ThemeHelper.PressedBrush="{telerik:VisualStudio2019Resource ResourceKey=ValidationBrush}" 
                         helpers:ThemeHelper.CheckedBrush="{telerik:VisualStudio2019Resource ResourceKey=AccentMainBrush}"/>

Changing Opacity

If you need to change the opacity of the disabled and read-only elements, you can easily do so by using the DisabledOpacity and ReadOnlyOpacity properties of the VisualStudio2019Palette. The default values are 0.3 and 0.6 respectively.

Example 5: Changing the opacity

VisualStudio2019Palette.Palette.DisabledOpacity = 0.5; 
VisualStudio2019Palette.Palette.ReadOnlyOpacity = 0.5; 

VisualStudio2019Palette.Palette.DisabledOpacity = 0.5 
VisualStudio2019Palette.Palette.ReadOnlyOpacity = 0.5
