1. Add 2 Listbox control in your aspx page.
2. Make the AutoPostBack Property of ListBox1 as True.
3. You can add Items to ListBox1 with the below codes.
ListItem item1= new ListItem();
item1.Text = "Joseph";
item1.Value = "1";
ListBox1.Items.Add(item1);
ListItem item2= new ListItem();
item2.Text = "AnkurDagar";
item2.Value = "1";
ListBox1.Items.Add(item2);
4. In the SelectedIndexChange event of the ListBox1, write the below code
ListItem additem= new ListItem();
additem.Text = ListBox1.SelectedItem.Text;
additem.Value =ListBox1.SelectedValue;
ListBox2.Items.Add(additem);

Try this.
