In het volgende voorbeeld worden waarden toegevoegd aan de Session eigenschap van een gebruikersbesturingselement. De myControl.Session.Add syntaxis voegt de waarden van twee TextBox webserverbesturingselementen toe aan de sessie die is gekoppeld aan het gebruikersbesturingselement en de pagina die deze bevat.

// Save state information which is used by display handler after the postback has occurred.
void SubmitBtn_Click(Object sender, EventArgs e) 
{
  // Clear all values from session state of 'Page'.
  Session.Clear();

  // Populate Session State of UserControl with the values entered by user.
  myControl.Session.Add("username",myControl.user.Text);
  myControl.Session.Add("password",myControl.password.Text);

  // Add UserControl state to the SessionState object of Page.
  Session[myControl.user.Text]= myControl;
  display.Enabled = true;
}

void Display_Click(Object sender, EventArgs e)
{
  int position = Session.Count - 1;

  // Extract stored UserControl from the session state of page.
  LogOnControl tempControl = (LogOnControl)Session[Session.Keys[position]];

  // Use SessionState of UserControl to display previously typed information.
  txtSession.Text = "<br /><br />User:" + tempControl.Session["username"] + "<br />Password : " + tempControl.Session["password"];
  display.Enabled = false;
}
