Office2013 Theme

The official Q3 2013 release of UI for WPF brought a brand new external theme with a flat modern UI and three color variations – White, Light Gray, Dark Gray.

The following topic explains the specifics of the theme's color variations and the available font options.

Theme Variations

The following are the supported color variations of the Office2013 theme

  • White: White color theme palette. This is also the default variation of the theme.

/// </summary>
public enum ColorVariation
    /// <summary>
    /// Represents Dark Grey Office2013 theme palette.
    /// </summary>

    /// <summary>
    /// Represents Light Grey Office2013 theme palette.
    /// </summary>

    /// <summary>
    /// Represents the default White Office2013 theme palette.
    /// </summary>

Theme Variation Changing

When using NoXAML assemblies in an application you should merge the necessary resource dictionaries from the corresponding theme assembly (in this case - Telerik.Windows.Themes.Office2013.dll). Alternitevely, you can merge the resource dictionaries as *.xaml files in your application (in case there is no reference to the theme assembly) in an appropriate place in your project (i.e. App.xaml). For more information about implicit styles refer to this article.

The Office2013 theme offers a very intuitive and easy way to change its color variation. You can change the variation by using the LoadPreset() method of Office2013Palette in the entry point of your application. You just have to pass to the method the desired color variation as a parameter.

For example, if you want to set the DarkGray color variation, you should have the following code-block in your application:

public MainWindow()

Changing Fonts

The official Q1 2015 release of Telerik UI for WPF introduced features that allow you to dynamically change the FontSize and FontFamily properties of all components in the application for the Office2013 theme.

All Telerik controls use resources that are linked to one major singleton object that contains the FontSize and FontFamily properties used for the Office2013 theme. These properties are public so you can easily modify the theme resources at one single point. The most commonly used FontSize in the theme is named FontSizeL and its default value is 15. The bigger font sizes are used for headers and footers while smaller ones are used inside complex controls such as RadRibbonView, RadGauge, RadGanttView, etc. As for the FontFamily - there is only one FontFamily resource which is named FontFamily and it is set to Calibri.

Please note that for complex scenarios we strongly recommend setting font size only initially before the application is initialized. We recommend font sizes between 11px and 19px for the FontSize property.

All the available FontSizes and FontFamily as well as their default values:

Office2013Palette.Palette.FontSizeXXS = 10;
Office2013Palette.Palette.FontSizeXS = 12; 
Office2013Palette.Palette.FontSizeS = 13;
Office2013Palette.Palette.FontSize = 14;
Office2013Palette.Palette.FontSizeL = 15;
Office2013Palette.Palette.FontSizeXL = 16;
Office2013Palette.Palette.FontFamily = new FontFamily("Calibri");

More details regarding the usage of the rarely used font sizes inside the different controls can be found below:
  • Office2013Palette.Palette.FontSizeXXS is used:

    • GridViewNewRow in Telerik.Windows.Controls.GridView
  • Office2013Palette.Palette.FontSizeXL is used:

    • ExpressionEditor in Telerik.Windows.Controls.Expressions
    • WizzardPage in Telerik.Windows.Controls.Navigation
    • ScheduleView's MonthView items in Telerik.Windows.Controls.ScheduleView

As the following example shows, you can change the default FontFamily from "Calibri" to "MonoType Corsiva" and the FontSize from 15 to 16 on a click of a button:

    <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">
        <telerik:RadCalendar x:Name="Calendar" Width="250" Height="250" Margin="4 10"/>
        <telerik:RadClock x:Name="Clock" Height="250" Margin="4 10" TimeInterval="0:0:1"/>
    <telerik:RadButton x:Name="BtnChangeFontSize" VerticalAlignment="Center" 
                       HorizontalAlignment="Center" Content="Change Font"
                       Click="OnButtonChangeFontSizeClick" />

private void OnButtonChangeFontSizeClick(object sender, RoutedEventArgs e)
    Office2013Palette.Palette.FontSize = 16;
    Office2013Palette.Palette.FontFamily = new FontFamily("MonoType Corsiva");

This will be the final result:
