How to Display items on demand on ListView/Datagrid with vertical scrollbar with mouse up and down using Wpf MVVM?

I have a listview which have can say 80+ records and each record have 7 images. When i display whole records then it take too much time and also consuming memory. I want to design wpf control, which display only records which can viewable on the page (suppose to be 6 records with assigned space). Suppose When user clicks on middle part of the scrollbar at position 50 then i have to show record from 45 to 50. please help me by giving any sample tutorial,references or by code.

thanks Ghacho

ListViews and DataGrids are virtualized (create controls only when visible) by default, you just need to use data-binding and data-templating instead of adding all the items manually (and thus forcing their creation).
