Passing session info to a popup

[dlhall]

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:

 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:

 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..

Thread moved to ASP.NET forum, since that's what it appears to be.

do strings work differently in ASP.NET? As far as I am aware, Strings don't have a .Text property... because the string IS the text... so I'm even sure that the code would even compile.

Hi,

When using Session variables, make sure to add null checking/handling in your popup.aspx page.

If Session("rptnum") IsNot Nothing Then
	Label1.text = DirectCast(Session("rptnum"), String)
End If
