Getting multiple selected values from listbox using binding?

Hi,

i want to get the list of multiple selected values  (Selction mode=extended) in listbox. through binding.

I saw some exampls using dependency property.

But i am interested to know how it can be done using Binding ? ex: selecteditems = {binding listofselectedvalues} , something like this!

May i kindly know how it can be done.
