RadListView raise SelectedItemChanged when click on up/down scroll bar

I am having this situation: when click on the scroll bar to up or down the RadListView the SelectedItemChanged event is raised. I have a work around in my client code to prevent it but it's ugly... somebody deal with it.

Steps to reproduce:

1) Have a RadListView in your form with many data to it shows the scroll bar 

2) Subscribe your for to the SelectedItemChanged event 

3) Run your form and select an item before use the scroll bar

4) click in the button to Up/Down the scroll bar. The subscribed is called (use some break point to check it)
