RadWindow showing inside a standard window?

[Martin]

I have a weird problem with a RadWIndow that is to replace the regular Window.

It's showing inside what appears to be a browser and I have no idea how to fix this.

 

Any ideas?

 

MainWindow.xaml

<telerik:RadWindow x:Class="TelerikWpfApp1.MainWindow"
                   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                   xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

    <telerik:RadWindow.Resources>
        <telerik:StringToGlyphConverter x:Key="StringToGlyphConverter" />
        <telerik:NullToVisibilityConverter x:Key="NullToVisibilityConverter" />
        <Style x:Key="ItemPreviewStyle" TargetType="telerik:RadNavigationViewItem">
            <Setter Property="IconTemplate">
                <Setter.Value>

                        <telerik:RadGlyph Glyph="{Binding Converter={StaticResource StringToGlyphConverter}}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                    </DataTemplate>
                </Setter.Value>
            </Setter>
        </Style>
        <Style x:Key="ItemBaseStyle" TargetType="telerik:RadNavigationViewItem" BasedOn="{StaticResource ItemPreviewStyle}">
            <Setter Property="Content" Value="{Binding Title}" />
            <Setter Property="ItemsSource" Value="{Binding SubItems}"/>
            <Setter Property="Icon" Value="{Binding Icon}" />
            <Setter Property="IconVisibility" Value="{Binding Icon, Converter={StaticResource NullToVisibilityConverter}}"/>
        </Style>

            <Setter Property="ItemContainerStyle" Value="{StaticResource ItemBaseStyle}"/>
        </Style>
    </telerik:RadWindow.Resources>
    <telerik:RadNavigationView x:Name="NavigationView" ItemsSource="{Binding Items}"
                               ItemContainerStyle="{StaticResource ItemStyle}"
                               AutoChangeDisplayMode="True"
                               DisplayMode="Expanded"
                               AllowMultipleExpandedItems="True"
                               SubItemsIndentation="40"
                               telerik:AnimationManager.IsAnimationEnabled="True"
                               Loaded="OnNavigationViewLoaded"
                               SelectionChanged="OnNavigationViewSelectionChanged">
        <Frame x:Name="frm"/>
    </telerik:RadNavigationView>
</telerik:RadWindow>

Hello Martin,

This happens if you set the RadWindow implementation (for example MainWindow.xaml) as a StartupUri of the application in the App.xaml file. To avoid this and show the window properly, remove the StartupUri and override the OnStartup() method of App.xaml.cs file. Then manually call the Show() method of the window.

This approach is shown in the following help article. Please give this approach a try and let me know how it goes.
