Scroll bar if items exceed itemControl

I have ItemControl

It displays one panel for each entry inside ObservableCollection.

My problem....

When the size of the ObservableCollection window grows, perhaps place more panels so that it only displays the first six panels.

So, the criteria, one panel for each record inside the ObservableCollection cannot be met.

So, I need to have a scroll bar so that I can access each panel. How can this be implemented?

See one screenshot below and Code here.

Thank......
