Why is MahApps unable to find Controls.AnimatedTabControl.xaml?

Question

I would like to use the Controls.AnimatedTabControl.xaml in my WPF project.

I added the line:

<ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.AnimatedTabControl.xaml" />

Like it's written in the documentation.

My app.xaml is now:

<Application x:Class="myAPP.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         StartupUri="MainWindow.xaml">
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Themes/Light.Blue.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
            <ResourceDictionary Source="Controls.TabControl.xaml"/>
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.AnimatedTabControl.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

VS shows me that an error has been encountered when seeking for the dictionary resource:

pack://application:,,,/MahApps.Metro;component/Styles/Controls.AnimatedTabControl.xaml

Any idea why?

The documentation for tab control is not up-to-date. In version 2.0.0 , all tab control styles were moved to the Controls.TabControl.xaml resource dictionary that is already included in Controls.xaml .

See the related change on GitHub: (GH-3587) All TabControl styles in one resource dictionary

In order to use the different styles, you have to replace your TabControl with the MahApps equivalent.

• For the AnimatedTabControl use <mah:MetroAnimatedTabControl>
• For the AnimatedSingleRowTabControl use <mah:MetroAnimatedSingleRowTabControl>
