scope resources to ResourceDictionary file

Question

hi
is it possible to make some value (ex: Double) scoped to it's ResourceDictionary file so it wouldn't be accessible elsewhere.

thanks in advance

I'm not aware of your specific use case, but one approach I used for sharing resources between styles is this:

PrivateResourceDictionary.xaml:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:MyApplication.Styles">

    <!-- Common resources for Menu, ContextMenu and MenuItem styles -->

    <!-- Do not merge this resource dictionary into any other resource dictionary!
         Otherwise, the resources may become visible to other parts of the application!
         Only use the resource dictionary directly from within a style or control template! -->

    <!-- Border color of the menu popup -->
    <SolidColorBrush x:Key="MenuPopupBorderBrush" Color="#ABABAB"/>

</ResourceDictionary>

OtherResourceDictionary.xaml:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:MyApplication.Styles">

    <Style TargetType="{x:Type ContextMenu}">

        <Style.Resources>
            <ResourceDictionary>

                <ResourceDictionary.MergedDictionaries>

                    <!-- Use resources from common resource dictionary -->
                    <ResourceDictionary Source="PrivateResourceDictionary.xaml"/>

                </ResourceDictionary.MergedDictionaries>

            </ResourceDictionary>
        </Style.Resources>

        <!-- You can define your style here and use the merged resources -->

    </Style>

</ResourceDictionary>

Just make sure that you merge your private resource dictionary only into the style itself but not into the using resource dictionary.

Hope this helps!
