Editor Padding Text

Hi,
I have created a custom render for editor and entry.
In the entry I can set the padding of the text like this:

Control.LeftView = new UIView(new CGRect(0, 0, 10, 0));
Control.LeftViewMode = UITextFieldViewMode.Always;
Control.RightView = new UIView(new CGRect(0, 0, 10, 0));
Control.RightViewMode = UITextFieldViewMode.Always;

But in editor I can find a way. Can you please help me?
