WPF: Virtualization along with Grouping

Hi All,

I am developing an application in which I want to use Virtulaization in a Listview along with grouping of elements. The moment I apply grouping and Expander to my group in the Listview the virtualization thing stops working. I knw Virtualisation works on Virtualising panel and grouping implements stack panel and thus Virtualization stope working.

Is there any workaround for the same if there is please do let me know as the requirement is little urgent.

Thanks in advance.
