add textbox
add eventhandler for Add button, retrieve text from textbox, store in db
add eventhandler for Show button, select list from db, render list

Update:
If you wnat the same button to act as both an Add and a show button:
add eventhandler for Add/Show button - retrieve text from button if text is "Add" execute add functionality, if text is "Show" execute show functionality. For the rest do as above.

Try this code:

C#

private ICollection<string> lst = new List<string>();
        private void btnAdd_Click(object sender, EventArgs e)
        {
            lst.Add(txtValue.Text);
        }
        private void btnShow_Click(object sender, EventArgs e)
        {
            listBox1.DataSource = lst;
            listBox1.DataBind();
        }
