I have a report number that is generated from a page, and I want to display that number in a popup window upon a button click that saves the report to a database. On the original page, here's the code that I am trying to use:
Code:
 Private Sub saverpt()
        Dim url As String = "popup.aspx"
        Dim s As String = "window.open('" & url + "', 'popup_window', 'width=300,height=100,left=100,top=100,resizable=yes');"
        ClientScript.RegisterStartupScript(Me.GetType(), "script", s, True)
        Session("rptnum") = rptnum.Text
On the popup.aspx page, here's what I am trying to make the rptnum field appear on:

Code:
 Private Sub popup_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim rptnum As String = CType(Session.Item("rptnum"), String)
        Label1.Text = rptnum.text
    End Sub
Currently, the popup will display "rptnum" rather than the actual generated report number. What am I missing? Thanks in advance..
