I've tested this with UI Catalog and it works wonderfully. Really nice work! Thanks.

Usage example:

private static void ListView_OpenSelectedItem (object sender, EventArgs e)
{
	var item = ((ListView)sender).SelectedItem;
	var itemName = ((ListView)sender).Source.ToList ();
	MessageBox.Query (50, 7, "Selected Item is: ", $"{item}:{itemName[item]}", "Ok");
}

In agreement and subscribing to what @tig mentioned in #447, I present the respective changes to the pending ListView PR. Now, by invoking any of these events, the desired values ​​in the 'e' argument can be obtained directly.

private static void ListView_SelectedChanged (object sender, ListViewItemEventArgs e)
{
	MessageBox.Query (50, 7, "Selected Item is: ", $"{e.Item}:{e.Value}", "Ok");
}

private static void ListView_OpenSelectedItem (object sender, ListViewItemEventArgs e)
{
	MessageBox.Query (50, 7, "Selected Item is: ", $"{e.Item}:{e.Value}", "Ok");
}

I love the change - a conflict came up after some recent merges, can we fix this, and then merge?

Ok after all the merges are done I'll fixes them.
