Question

I’m using ASP.net 4.0 VB 🙂

I am using a session variable to add a user entered code into the url of each page. I can get the code to show up at the end of the page’s URL that my textbox is on, but what do I add to every page to make sure that the session stays at the end of every URL that person visits during their session? This is the code from the page that the user enters their user code.

  Protected Sub IBTextBoxButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles IBTextBoxButton.Click
  Session("IB") = IBTextBox.Text
  Dim IB As String = Session("IB")
End Sub


 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 ProductID.Value = Request.QueryString("id")
 If Session("IB") Is Nothing Then
     tab4.Visible = "False"
 Else
     tab4.Visible = "True"

 End If
End Sub

This is what I have in the page load of one of the other pages. What else do I add to make sure that variable is added to the URL of that page?

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Dim IB As String
    IB = Session("IB")
End Sub

I threw this code into the Master Page to make sure that every page knows whether or not the Session is there. Thanks for all the help everyone!

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) 
Handles Me.Load
  If Session("IB") Is Nothing Then

    IBText.Visible = True
    IBTextBox.Visible = True
    IBTextBoxButton.Visible = True
  Else

    IBText.Visible = False
    IBTextBox.Visible = False
    IBTextBoxButton.Visible = False
    lblIB.Visible = True

    lblIB.Text = "Welcome, " + Session("First_Name") + " " + Session("Last_Name")
  End If
End Sub
