vulpes code is working fine but,

Use the below namespace and set Autopostback property of DropDownList2 to true
using System.Collections.Generic;

One way of doing it would be to use a Dictionary:

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Dictionary dict = new Dictionary();
Session["Dictionary"] = dict;
}
}

protected void Button1_Click(object sender, EventArgs e)
{
DropDownList2.Items.Add(DropDownList1.SelectedItem.Text);
Dictionary dict = (Dictionary)Session["Dictionary"];
dict.Add(DropDownList1.SelectedItem.Text, TextBox1.Text + "," + TextBox2.Text);
}

protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
Dictionary dict = (Dictionary)Session["Dictionary"];
string[] items = dict[DropDownList2.SelectedItem.Text].Split(',');
TextBox1.Text = items[0];
TextBox2.Text = items[1];
}
