Answer 1

First, you have to define a model for your Listbox :

public class MyModel
{
    public int Id { get; set; }
    public string Description { get; set; }
}

After you can set items like this :

listBox2.Items.Add(new MyModel() { Id = 1, Description = "description" });
listBox2.DisplayMember = "Description";
listBox2.ValueMember = "Id";

And now, your listbox will show the description property. If you select an item, the SelectedValue in listbox2 will be the value of id property

Answer 2

Use SqlDataAdapter to dump data into the listbox from the data source and based on the data selected in one of the listbox use listbox.add() method, Use a "for" loop to dump the data from one listbox to another using an index.

for(int i=0; i<listBox1.SelectedItems.Count; i++)
{
    listBox2.Items.Add(listbox1.SelectedItems[i].toString());
}

Answer 3

    if (listBox1.SelectedItem != null)
        {
            listBox2.Items.Add(listBox1.SelectedItem);
        }
        listBox2.DisplayMember = "Descripcion";
        listBox2.ValueMember = "Id";

this is working fine....
