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)
