Cannot use Virtual Scroll with Server binding

[Robert]

I'm really new at KendoUI.  Just learning it in fact.

I just got this exception (see title) and I really don't know what it means, or why I can't do it.
I'm using an MVC 4 framework in VS 2012

So... some questions.

1. I know what virtual scrolling is, What is Server binding?
2. How do I know if I'm doing Server binding?
3. Is there a way to work around this?

Thanks
Robert
