I'm getting XAML-blind I'm afraid. I'm developing a MS Surface application and I have an ellipse inside a ScatterViewItem (a container an end user can resize). I would like to keep the ellipse a circle (width == height) and keep it as big as possible (the lowest value of width/height of the SVI should be taken for both width/height properties of the ellipse).
A XAML only solution (using property triggers or similar) is prefered.
Your help is much appreciated as always.
