Examples

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 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;
}

' Saves state information which is used by display handler after the postback has occurred.

Sub SubmitBtn_Click(Sender As Object, e As EventArgs) 

    ' 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
End Sub

Sub Display_Click(Sender As Object,e As EventArgs)

    Dim position As Integer = Session.Count - 1

    ' Extract stored UserControl from the session state of page.
    Dim tempControl As LogOnControl = CType(Session(Session.Keys(position)),LogOnControl)

    ' 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
End Sub
