    This works for making a square button:

    Height = "{Binding Path=ActualWidth, RelativeSource={RelativeSource Self}}"

    I would like a aspect ratio of 1 to 5 though. Something like this:

    Height = "{Binding Path=ActualWidth/5.0, RelativeSource={RelativeSource Self}}"

    That does not compile though.

    I have attempted to use c# to make a square button:

    Button button = (Button)FindName("ButtonStart");
            var myBinding = new Binding("Height")
            {
                Source = button.ActualWidth
            };
            button.SetBinding(Button.HeightProperty, myBinding);

    This doesn't make the button square. 

    Is it possible to set the aspect ratio of a button using data binding?

    Hi JohnGlen244,

    Thank you for posting here.

    This simple code should work.

    ButtonStart.Height = ButtonStart.Width / 5;

    You can also refer to the suggestions in this link to implement the aspect ratio setting in xaml.

    How perform calculation on a XAML Binding value: reverse it, multiply it, subtract from it or add to it?

    Best Regards,

    Timon

    Where do I put that code? The button has a height of 0 in the Window constructor.
