First of all, please accept our apologies for the missing article. We scheduled this problem and the page should be soon accessible.
In order to change the Expander header you have to make changes in its style.
Moving the Expander Decorator to the right and Header Content to the left can be done by resetting their columns in the grid they are contained. Then you have to disable the default animation for the "DirectionDown" visual state ( in case you use this direction).
Please examine the attached solution and feel free to ask if you need further assistance.
