How to apply Application wide resource dictionary inside a custom control?

[Syed Danish]

I have resource dictionary declaration inside a Usercontrol like this:

<UserControl.Resources>
        <ResourceDictionary Source="/Phoenix.CAG;Component/Themes/Black.xaml"/>
</UserControl.Resources>

I want to put the resource dictionary only in the App.xaml and let it apply in this usercontrol. Right now I also have this declared inside my app.xaml as

<Application.Resources>
        <ResourceDictionary Source="/Phoenix.CAG;Component/Themes/Black.xaml"/>
</Application.Resources>

 Is there any way to stop repeating the use of the same resource dictionary name in multiple places and put them only in one location and make it work?

Can you please let me know how can I do that?

Hi Syed Danish,

From what  I see you are referencing a resource dictionary in a different assemly.

I would suggest that you create a separate Silverlight Class Library which contains a single ResourceDictionary file and then reference this from all other projects that are part of your solution.

Add a reference to the newly created ResourceDictionary as a MergedResourceDictionary in the App.xaml file in each of your projects. For example:

<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             x:Class="Resources_From_Different_Aseembly.App"
             >
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/MyTheme;component/Generic.xaml" />
            </ResourceDictionary.MergedDictionaries>
                </ResourceDictionary>
    </Application.Resources>
</Application>

where Generic.xaml is the new ResourceDictionary.

Styles from Generic.xaml will be applied to all UserControls residing in the projects which reference the custom class library.

I hope this will help you achieve your goal. Please, write back in case you need further help.
