Programmatically change margin of an Ellipse C#

I am writing a little Timemanagement Tool which shows when I can leave to fulfill my contractual working hours. The tool looks like this: Tool Screenshot I want to make it resizable, so i tried to set all form in relation of the window height and width. This looks like 

     public void resizeElements()
    {
        clockBody.Height = this.Height / (300/248);
        clockBody.Width = this.Width / (300/248);
        double marginClock = Math.Round((this.Height - clockBody.Height) / 2);
        clockBody.Margin = new Thickness(marginClock);
        recHr.Height = this.Height / (300 / 50);
        recHr.Width = this.Width / (300/6);
        recMin.Height = this.Height / (300/80);
        recMin.Width = this.Width / (300 / 4);
        recSec.Height = this.Height / (300/118);
        recSec.Width = this.Width / (300/4);
    }

As you can see in the picture the clockbody is not as big as the Window, so I tried to set it margin to Math.Round((this.Height - clockBody.Height) / 2); but this throws an System.ArgumentException calling:

'System.ArgumentException' in WindowsBase.dll ("'Auto,Auto,Auto,Auto' is not a valid value for property 'Margin'.")

If i edit the code like clockBody.Margin = new Thickness(26); ((300-248)/2) I can run the Application. But thats not dynamic. Any ideas?

try to use ActualWidth and ActualHeigth properties instead of Width and Height.
