How can I make a WPF Expander Stretch?

Question

The Expander control in WPF does not stretch to fill all the available space. Is there any solutions in XAML for this?

Answer 1

Non stretchable Expanders is usually the problem of non stretchable parent controls.. Perhaps one of the parent controls has defined a HorizontalAlignment or VerticalAlignment property?

If you can post some sample code, we can give you a better answer.
