Setup through C# code behind?

Hi,

I have create a custom ContentPage that acts as a base page for the majority of the pages in the app. I have create a property called IsDebug, so that any pages that is based on this content page can simply change the IsDebug to true and it will turn on the debug rainbow.

In the BasePage I have this - Xaml -

xmlns:rainbows="clr-namespace:Xamarin.Forms.DebugRainbows;assembly=Xamarin.Forms.DebugRainbows"
rainbows:DebugRainbow.IsDebug="False"

Code behind -

[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class BasePage : ContentPage
{
    public IList<View> BasePageContent => BaseContent.Children;

    public static readonly BindableProperty IsDebugProperty = BindableProperty.Create(nameof(IsDebug), typeof(bool), typeof(BasePage), false, defaultBindingMode: BindingMode.OneWay, propertyChanged: IsDebugChanged);
    public bool IsDebug
    {
        get => (bool)GetValue(IsDebugProperty);
        set => SetValue(IsDebugProperty, value);
    }
    public BasePage()
    {
        InitializeComponent();
    }

    private static void IsDebugChanged(BindableObject bindable, object oldValue, object newValue)
    {

        if (bindable != null && bindable is BasePage basePage)
        {
            // Enable or disable rainbow debug

        }
    }
}

Issue is im not sure how to set the value of rainbows:DebugRainbow.IsDebug="False" from the code behind.

Something like this should work?

DebugRainbow.SetIsDebug(basePage, (bool)newValue);

or

basePage.SetValue(DebugRainbow.IsDebugProperty, (bool)newValue);
