An HttpSessionState object associated with the Page that contains the UserControl instance.

The following example adds values to the Session property of a user control. The myControl.Session.Add syntax inserts the values of two TextBox Web server controls to the session associated with the user control and the page that contains it.

// Save state information which is used by display handler after the postback has occured.
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;
}

// Save state information which is used by display handler after the
// postback has occured.
void SubmitBtn_Click(Object sender, EventArgs e) 
{
    // Clear all values from session state of 'Page'.
    get_Session().Clear();
    // Populate Session State of UserControl with the values entered by user.
    myControl.get_Session().Add("username",myControl.user.get_Text());
    myControl.get_Session().Add("password",myControl.password.get_Text());
    // Add UserControl state to the SessionState object of Page.
    get_Session() .set_Item( myControl.user.get_Text() , myControl );
    display.set_Enabled(true);
} //SubmitBtn_Click

void Display_Click(Object sender, EventArgs e)
{
    int position = get_Session().get_Count() - 1;
    // Extract stored UserControl from the session state of page.
    LogOnControl tempControl = (LogOnControl)(get_Session().get_Item(
        get_Session().get_Keys().get_Item(position)));
    // Use SessionState of UserControl to display previously typed
    // information.
    txtSession.set_Text("<br /><br />User:" 
        + tempControl.get_Session().get_Item("username") + "<br />Password : "
        + tempControl.get_Session().get_Item("password"));
    display.set_Enabled(false);
} //Display_Click
