Hi Syncfushion team
        our company had purchased syncfushion product of version 10.404.0.71. and we used WPF treeviewADV in our project. but due to we need bind more than thousands of items,so we use UI virtualization, set IsVirtualizing="True"  VirtualizationMode="Extended", according to the demo UI Virtualization which you had provided.  the issue is the vertical scroll bar can't adapt the content special when collapse the parent node but chind node still expand.  and sometimes the items that located most below can't show...just like your demo , you can see when expand a node in your demo project, you down the scroll bar you can't see the the item Module 999...
       can you help me solve this kind of scroll bar issue?   thanks
