You can register to ListView's ItemSelectionChangedEvent instead.

        this.listView1.ItemSelectionChanged += this.HandleOnListViewItemSelectionChanged;

        private void HandleOnListViewItemSelectionChanged(Object sender, ListViewItemSelectionChangedEventArgs e)
        {
            if (e.IsSelected)
            {
                this.detailsLabel.Text = this.GetDetails(e.Item);
            }
            else
            {
                this.detailsLabel.Text = String.Empty;
            }
        }
