Telerik blogs

With the recent R2 2023 release, we are excited to announce a game-changing addition to our Windows 11 theme that will elevate your user experience—the new high-density (or Compact) layout option.

Themes are instrumental in enhancing the overall user experience, breathing life into the user interface, and reflecting your product’s branding and style.

Last year, after we launched the Windows 11 theme for Progress Telerik UI for WPF, we heard from many of you who were looking for a sleeker and more compact design. Instead of creating an entirely new theme, we decided to optimize the use of existing resources by utilizing all the colors from the current theme. And let me tell you, the result is truly impressive.

In this blog post, I will introduce to you the Windows11ThemeSizeHelper, a revolutionary way for the Windows 11 theme that empowers you to take your WPF application to new heights of visual appeal and customization.

Understanding the Windows11ThemeSizeHelper

Let’s dive into the world of the Windows11ThemeSizeHelper. This powerful and innovative helper is specifically designed for our Windows 11 theme. Its primary function is to switch between two distinct layouts using the IsInCompactMode property. By leveraging this property, the helper combines various resources, adapting the sizes to provide larger dimensions tailored for Windows 11 Standard, and effortlessly transitioning to more compact dimensions for Windows 11 Compact.

Easy Implementation

Integrating themes into your applications can be challenging for the developers sometimes. That’s why we’ve made it our mission to create a streamlined and straightforward process. With just one line of code, you’ll be able to apply Windows 11 Compact Mode and witness an instant transformation in the look and feel of your entire application:

Windows11ThemeSizeHelper.Helper.IsInCompactMode = true;

Customizing the Dimensions

But wait, there’s more! I thought it would be nice of me to also show you a way of customizing the dimensions of the Windows 11 theme. Let’s consider a practical example where we create two StackPanels—one using the Standard Windows11 layout and another where we’ll modify specific resources within the StackPanel scope. The possibilities for customization are truly endless!

<StackPanel Orientation="Horizontal">
    <telerik:GroupBox Header="Windows11" HorizontalAlignment="Left" Width="350">
            <telerik:RadButton Content="Button"/>
            <telerik:RadListBox Margin="0 8">
                <telerik:RadListBoxItem>Item 1</telerik:RadListBoxItem>
                <telerik:RadListBoxItem>Item 2</telerik:RadListBoxItem>
                <telerik:RadListBoxItem>Item 3</telerik:RadListBoxItem>
            <telerik:RadWatermarkTextBox Text="WatermarkTextBox"/>
    <telerik:GroupBox Header="Windows11 Customized" HorizontalAlignment="Left" Width="350" Margin="8 0 0 0">
                <!-- Customized Windows 11 resources with ThemeSizeHelper  -->
                <sys:Double x:Key="{x:Static telerik:Windows11ResourceKey.DefaultControlMinHeight}">25</sys:Double>
                <sys:Double x:Key="{x:Static telerik:Windows11ResourceKey.DefaultItemMinHeight}">24</sys:Double>
                <sys:Double x:Key="{x:Static telerik:Windows11ResourceKey.FontSize}">13</sys:Double>
                <Thickness  x:Key="{x:Static telerik:Windows11ResourceKey.DefaultControlPadding}">8 0</Thickness>
                <Thickness  x:Key="{x:Static telerik:Windows11ResourceKey.NestedButtonMargin}">0 0 8 0</Thickness>
                <Thickness  x:Key="{x:Static telerik:Windows11ResourceKey.InputPadding}">4 1 4 1</Thickness>
            <telerik:RadButton Content="Button"/>
            <telerik:RadListBox Margin="0 8" >
                <telerik:RadListBoxItem>Item 1</telerik:RadListBoxItem>
                <telerik:RadListBoxItem>Item 2</telerik:RadListBoxItem>
                <telerik:RadListBoxItem>Item 3</telerik:RadListBoxItem>
            <telerik:RadWatermarkTextBox Text="WatermarkTextBox"/>

And voilà! Feast your eyes on the result:
