Question

on my website I have an “Enroll” page where users submit some basic information, there’s some basic validation on that page then the user is taken to an “Enrollment Confirmed” page (which i don’t want to display the info from previous page). On the confirmation page there is link to a “Print Enrollment Confirmation” page which, on this page, I want to contain the information entered from the “Enroll” page. So basically, I want the input entered on “Page 1” put into labels on “Page 3”. I’ve seen some examples of transferring information from “Page 1” to “Page 2” but I have an extra page users need to go through before hitting the page with their previously entered data.

Can someone give me an explanation on how I could do this without using query strings? Thank you.

Answer 1

You could create an class with properties for each form field then store it in the session. Then after you populate what you need on page 3 remove it from the session.

Example

Class:

 <Serializable()>
Public Class Input
    Private _FirstName As String = String.Empty
    Private _LastName As String = String.Empty

    Public Property FirstName As String
        Get
            Return _FirstName
        End Get
        Set(ByVal value As String)
            _FirstName = value
        End Set
    End Property

    Public Property LastName As String
        Get
            Return _FirstName
        End Get
        Set(ByVal value As String)
            _FirstName = value
        End Set
    End Property

    Public Sub New()
    End Sub
End Class

Storing data:

Private Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
    Dim FormData As New Input()
    FormData.FirstName = txtFirstName.Text
    FormData.LastName = txtLastName.Text
    Session("InputData") = FormData

End Sub

Retrieving it:

   If Not IsNothing(Session("InputData")) Then
       Dim FormData As Input = DirectCast(Session("InputData"), Input)
       txtFirstName.Text = FormData.FirstName
       txtLastName.Text = FormData.LastName
       Session.Remove("InputData")
   End If
