Apply same dynamic style to all elements of same kind in grid

Question

I have a Grid full of Labels that all use the same style which is a DynamicResource:

<Label Grid.Row="0" Style="{DynamicResource MyStyle}"/>
<Label Grid.Row="1" Style="{DynamicResource MyStyle}"/>
<Label Grid.Row="2" Style="{DynamicResource MyStyle}"/>

Is there a way to only set the style once for all labels in the grid? I tried it this way, however BasedOn doesn't work with DynamicResources.

One way to do it is to use MergedDictionaries like so:

<UserControl.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/assemblyName;component/yourStyle.xaml"/>
        </ResourceDictionary.MergedDictionaries>
        <!--If you want to include additional resources you need to place them here-->
        <SolidColorBrush x:Key="TextBox.Static.Border" Color="#FFABAdB3"/>
    </ResourceDictionary>
</UserControl.Resources>

Then in your Grid you can use it like so:

<Grid>
    <Grid.Resources><!-- This will only use the style in the Grid-->
        <Style TargetType="Label" BasedOn="{StaticResource MyStyle}"/>
    </Grid.Resources>
</Grid>  

And this should now use your Style only for the Grid or a Label where Style="{StaticResource myStyle}".
