Hi all

I want to apply the Office2013Theme with ThemeManager on my XamRibbonWindow but it does not work. I try as follow

The XAML file

<ribbon:XamRibbonWindow x:Class="BackupCustomizing.MainWindow"
                        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
                        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
                        xmlns:ribbon="http://schemas.infragistics.com/xaml/wpf"
                        xmlns:view="clr-namespace:BackupCustomizing.Views"
                        xmlns:ignore="http://www.ignore.com"
                        mc:Ignorable="d ignore"
                        Height="400"
                        Width="800"
                        Title="Backup customizing"
                        DataContext="{Binding Main, Source={StaticResource Locator}}" ResizeMode="NoResize" >

    <ribbon:RibbonWindowContentHost x:Name="contentHost"
                                    Theme="Office2013"
                                    ribbon:RibbonWindowContentHost.ApplicationAccentColor="#0072C6">

        <Grid x:Name="LayoutRoot">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="230" />
                <ColumnDefinition Width="*" />
            </Grid.ColumnDefinitions>

            <view:NavigationView Grid.Column="0" Padding="10 0 0 0" />
        </Grid>
    </ribbon:RibbonWindowContentHost>
</ribbon:XamRibbonWindow>

and the code

using BackupCustomizing.ViewModel;
using Infragistics.Themes;
using Infragistics.Windows.Ribbon;

namespace BackupCustomizing
{
    /// <summary>
    ///     Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : XamRibbonWindow
    {
        /// <summary>
        ///     Initializes a new instance of the MainWindow class.
        /// </summary>
        public MainWindow()
        {
            InitializeComponent();
            ThemeManager.SetTheme(contentHost, new Office2013Theme());
            Closing += (s, e) => ViewModelLocator.Cleanup();
            
        }
    }
}

But the wpf controls show me with windows default theme,

What am I doing wrong?

Thanks
