Centering selected item in a scroll viewer

Question

I am trying to center a selected item in a ListView inside a ScrollViewer and struggling to calculate the vertical offset that I should be setting the ScrollViewer relative

Answer 1

Yup, this worked for me out of the box with ScrollIntoView

    private void CountKeyBoard_NavigationEvent(object sender, Controls.UserControls.NavigationEventArgs e)
    {
        if (lvInvDetails.SelectedItem != null && lvInvDetails.SelectedIndex != -1)
        {
            switch (e.Direction)
            {
                case Controls.UserControls.NavigationEventArgs.DirectionEnum.NEXT:
                    if (lvInvDetails.SelectedIndex >= (lvInvDetails.Items.Count - 1))
                        lvInvDetails.SelectedIndex = 0;
                    else
                        lvInvDetails.SelectedIndex++;
                    break;

                case Controls.UserControls.NavigationEventArgs.DirectionEnum.PREVIOUS:
                    if (lvInvDetails.SelectedIndex > 0)
                        lvInvDetails.SelectedIndex--;
                    else
                        lvInvDetails.SelectedIndex = lvInvDetails.Items.Count - 1;
                    break;
            }
            lvInvDetails.ScrollIntoView(lvInvDetails.SelectedItem);
        }
    }
