Palette Settings not Working When Using RadSplashScreen

Updated on Sep 15, 2025

Environment

Product Version	2020.3.1020
Product	RadSplashScreen for WPF

Description

The palette settings are not working if you apply them just before openning a RadSplashScreen in the App's OnStartup override. The following code snippet shows this setup.

C#

	protected override void OnStartup(StartupEventArgs e)
    {
		StyleManager.ApplicationTheme = new FluentTheme();
		// The following palette setting won't be applied neither in the RadSplashScreen or the Telerik controls in the main window.
		FluentPalette.Palette.AccentColor = Colors.Red;
		
		RadSplashScreenManager.Show();
		Thread.Sleep(5000);
		// show window here
		RadSplashScreenManager.Close();
	}

Solution

To resolve this, create a UserControl that hosts RadSplashScreen instance and apply the platte settings in the constructor of the UserControl. Then use the generic Show method in order to display it.

XAML

	<UserControl x:Class="WpfApp1.SplashScreenUserControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:WpfApp1" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
		<UserControl.Resources>
			<telerik:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter" />
		</UserControl.Resources>
		<telerik:RadSplashScreen Content="{Binding Content}"
								 ImagePath="{Binding ImagePath}"
								 ImageStretch="{Binding ImageStretch}"
								 ImageWidth="{Binding ImageWidth}"
								 ImageHeight="{Binding ImageHeight}"
								 Footer="{Binding Footer}"
								 Cursor="{Binding MouseCursor}"
								 HorizontalContentAlignment="{Binding HorizontalContentAlignment}"
								 HorizontalFooterAlignment="{Binding VerticalContentAlignment}"
								 ProgressValue="{Binding ProgressValue}"
								 MaxValue="{Binding MaxValue}"
								 MinValue="{Binding MinValue}"
								 IsIndeterminate="{Binding IsIndeterminate}"
								 ProgressBarVisibility="{Binding IsProgressBarVisible, Converter={StaticResource BooleanToVisibilityConverter}}"/>
	</UserControl>

C#

	public partial class SplashScreenUserControl : UserControl
    {
        public SplashScreenUserControl()
        {
            FluentPalette.Palette.AccentColor = Colors.Red;
			
            InitializeComponent();
        }
    }

C#

	protected override void OnStartup(StartupEventArgs e)
    {
		StyleManager.ApplicationTheme = new FluentTheme();		
		RadSplashScreenManager.Show<SplashScreenUserControl>();
		Thread.Sleep(5000);
		// show window here
		RadSplashScreenManager.Close();
	}
