I found the sample code of "Nick Miller" on the following question: mvvm how to make a list view auto scroll to a new Item in a list view
This partly answers my question because scrolling works very close, but I need the user can stop automatic scrolling.
To do this I added a checkbox, and in the eveinement puts it true or false the variable listbox.autoscroll, but this has no effect despite the fact that the code will change the property.
I have not changed the Nick Miller code on the LoggingListBox class.

<CheckBox x:Name="ChkAutoScroll"
Margin="10"
Content="Auto Scroll"
Click="ChkAutoScroll_Click"/>
</StackPanel>
</Grid>
</Window>
Private Sub ChkAutoScroll_Click(sender As Object, e As RoutedEventArgs)
If (ChkAutoScroll.IsChecked = True) Then
Listbox1.AutoScroll = True
Else
Listbox1.AutoScroll = False
End If
End Sub
There is no error message, but scrolling is still active despite the AutoScroll value change.
