	<%@ Page Language="C#" %>

	<script runat="server">
	 protected void Button1_Click(object sender, EventArgs e)
	 {
	 ListBox1.Items.Add(TextBox1.Text.ToString());
	 }

	 protected void Button2_Click(object sender, EventArgs e)
	 {
	 Label1.Text = "You selected from the ListBox:";
	 foreach (ListItem li in ListBox1.Items) {
	 if (li.Selected == true) {
	 Label1.Text += li.Text + "";
	 }
	 }
	 }
	</script>

	<html xmlns="http://www.w3.org/1999/xhtml" >
