Answer 1

    <Grid>
        <ListView x:Name="lvw" 
                  MouseDoubleClick="ListView_MouseDoubleClick">
            <ListView.Items>
                <ListViewItem>item1</ListViewItem>
                <ListViewItem>item2</ListViewItem>
            </ListView.Items>
        </ListView>
    </Grid>

        private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e)
        {
            object o = lvw.SelectedItem;
            if (o == null)
                return;
            ListViewItem item = o as ListViewItem;
            MessageBox.Show(item.Content.ToString());
        }
