Hello igal a,

In order to rotate the expander, you have to edit the template in the Blend. You can apply  a custom theme to any of  the controls. For more information you can follow the link below:

Please find attached an example.

If you have further more questions please do not hesitate to ask us.
I hope this will help you.

Sincerely yours,
Dimitrina
