Remove Border on Picker Control

Hey everyone

How does one remove the 1 pixel grey border on the Picker in a XAML page for the iOS project.

I added the following to an Effect
Control.Layer.BorderColor = UIColor.Clear.CGColor; Control.Layer.BorderWidth = 0;
The border is still there?

In Xcode I would show a UIPickerView when a UITextField is tapped and thus make the custom styling changes to the Text Field.

Would I be right in assuming the XAML 'Picker' control somehow contains a UITextField and a UIPickerView, if so, how do I stylise the UITextField?

Thnxs!
