The scrolling behavior using the mouse wheel is determined by the value of the static System.Windows.Forms.MouseWheelScrollLines property. In order to alter the default implementation, you would need to use a custom RadListView control.
I am sending you attached a sample project and a short video showing the result on my end.
I hope this helps. Should you have further questions please do not hesitate to write back.
