xamarin - propagate the change of a bindable property to the ios renderer

Question

I created a custom control as extension of EntryCell with a bindable property. I implemented the renderer on ios by extending EntryCellRenderer. I would like to Change a property of my renderer when the bindable property changes. EntryCellRenderer has a static Methode OnCellPropertyChanged, which I can't override in my renderer. Any Idea how could I achieve that?

Best thanks for your Help

Sounds like the exact reason for the OnElementPropertyChanged method that you can override in the custom renderer.

protected override void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e) {
    base.OnElementPropertyChanged(sender, e);

    if(e.PropertyName == CustomEntryCell.MyCustomThingProperty.PropertyName) { //Make sure to check against your BinableProperty.PropertyName like I am doing here
        //Make your change here
    }
}
