UWP RequestedTheme in resource dictionary - xaml

Question

So I am designing an app that dynamically themes itself based upon an API response. I have been able to programmatically set the colors in the resource dictionary for the rest of my app but I am trying to find out how to set get the button and AppBarButton hover and click colors to fit in my color scheme. I have previously changed this by hardcoding the RequestedTheme property in the required elements.
Is there a way to bind the RequestedTheme property to a static resource set in a resource dictionary that I am able to set programmatically? I am open to accomplishing the theming of the buttons differently if need be but would like to avoid having to bind to a local variable on each page if possible.
Thanks so much!

You could define a custom theme resource class like the following:
public enum MyTheme
{
//
// Summary:
// Use the Application.RequestedTheme value for the element. This is the default.
Default = 0,
//
// Summary:
// Use the **Light** default theme.
Light = 1,
//
// Summary:
// Use the **Dark** default theme.
Dark = 2
}
Then, in resource dictionary, you could define your different theme resource:
<Application.Resources>
<local:MyTheme x:Key="MyTheme">Light</local:MyTheme>
</Application.Resources>
In XAML page, you could reference to it:
<Button Content="test" RequestedTheme="{StaticResource MyTheme}"></Button>
You can then change the value in code with:
App.Current.Resources["MyTheme"] = isThemeDark ? "Dark" : "Light";
