public partial class Form1 : Form
{
    List<String> mylistSource;

    public Form1()
    {
        InitializeComponent();
        mylistSource = new List<string>();
        // populate source with test data
        for (int i = 0; i < 25; i++)
        {
            mylistSource.Add(i.ToString());
        }

        //assign source to both lists
        listBox1.DataSource = mylistSource;
        listBox2.DataSource = mylistSource;
    }
}

Just add 2 listboxes to a form and paste in code to run.

or if you just want to copy selected items you can simply do this:

foreach (var item in listBox1.SelectedItems)
{
    listBox3.Items.Add(item);
}

If you want to select the entire items from listbox1 to listbox2, then the easiest, most readable and fastest have to be:

listbox2.Items.AddRange(listbox1.Items);

In case of web form, use session to forward the data source of the list.

what you could do, is give the objects an extra property (eg. selected)

you bidn the collection to both the listboxes, but in the one you only show the ones with selected = false and in the other selected = true

and if you "move" the item, you just need to switch selected to true and refresh the ItemsSources
