Page load question

[Goober]

I have a page that receives a session variable from the default.aspx.
On Page load, the code in Page load gets executed twice. So far, no
problem. It sets the session variable each time, correctly.

However, when I click on a menu item in that page, it then executes the
same page load twice, before transferring control (via a
response.redire ct) to the new page. On the first pass through the page
load of the menu page, the session variable appears to be set to
nothing, when at the end of the first page load it was set properly.
What's happening with this code? I can provide some examples if needed.

Here you are:

Here's where it gets set in the default.aspx.vb section

sCalendar = sCalendar.Repla ce(":", ".")
Session("Calend ar") = objReader.GetDa teTime(4).ToStr ing
Session("ViewPr odHierSKUStatus ") = objReader.GetSt ring(8)
Session("ViewOl dSys") = objReader.GetSt ring(9)
Session("Permis sion") = objReader.GetSt ring(10)
Response.Cookie s("availability rptlevel").Valu e =
objReader.GetSt ring(11)
---> Session("availa bilityrptlevel" ) = objReader.GetSt ring(11)
TransactionLog( "")
Server.Transfer ("sales/newmenu.aspx?Us er=" &
objReader.GetSt ring(2) & "&Name=" & objReader.GetSt ring(3) & "&Sales=" &
sSales & "&Calendar= " & sCalendar & "&P=" & objReader.GetSt ring(6) &
"&Pass=" & objReader.GetSt ring(1) & "&Act=" & objReader.GetSt ring(7) &
"&SKUStat=" & Session("ViewPr odHierSKUStatus ") & "&Oldsys=" &
Session("ViewOl dSys") & "&Permissio n=" & Session("Permis sion"))
Here is the page load piece
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load

If Request.QuerySt ring("User") = "" Then
lblUser.Text = Session("UserNa me")
End If

If Session("Sales" ) = "" Then
Session("Permis sion") = Request.QuerySt ring("P")
Session("Pass") = Request.QuerySt ring("Pass")
Session("UserNa me") = Request.QuerySt ring("Name")
Session("ActUse r") = Request.QuerySt ring("Act")
Session("User") = Request.QuerySt ring("User")
Session("Sales" ) = Request.QuerySt ring("Sales")
Session("Calend ar") = Request.QuerySt ring("Calendar" )
Session("Sales" ) = Session("Sales" ).replace("-", "/")
Session("Sales" ) = Session("Sales" ).replace(".", ":")
Session("Calend ar") = Session("Calend ar").replace( "-", "/")
Session("Calend ar") = Session("Calend ar").replace(". ", ":")
Session("ViewPr odHierSKUStatus ") =
Request.QuerySt ring("SKUStat")
Session("ViewOl dSys") = Request.QuerySt ring("Oldsys")
End If

If Session("UserNa me") = "" Then
Server.Transfer ("../Default.aspx")
End If
Session("ActUse r") = UCase(Session(" ActUser"))

Dim xxyz As String
--> xxyz = Session("availa bilityrptlevel" )

the above setting it equal to a string is just some test code I put in
to make sure it was getting set in this code, and was picking up the
right info in it.
When it get set = to "04" in the first part of the code (at the
objreader.getst ring), it is set, and then gets passed into newmenu.aspx.

When it hits newmenu.aspx, it runs thru this code twice (below the xxyz
is just some stuff it does with which menu items show up for which
users). When the page loads, it is still set to "04". However, when I
click on the menu item, it hits page load again, and it sets the session
variable = to nothing.

the most common cause for this is you actually assign the onload handler
twice, look in oninit section.

This is the code that is immediately prior to the page load. Do not see
where I'm calling it twice.

#Region " Web Form Designer Generated Code "

'This call is required by the Web Form Designer.
<System.Diagnos tics.DebuggerSt epThrough()> Private Sub
InitializeCompo nent()

End Sub

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Init
'CODEGEN: This method call is required by the Web Form Designer
'Do not modify it using the code editor.
InitializeCompo nent()
End Sub

#End Region

Make sure you aren't hookup up the event in InitializeCompo nent() as well as
setting AutoEventWireup to true in the aspx @Page directive.

If the page you have described is set as the "default document" in IIS for
this folder, there can be another reason for the double loading of the page:

if you have on the page somthing like <img src=''>, than IE thinks that the
source of the image is the current path, which is your current directory.
IIS will translate this and will think the browser asked for the default
document - which is your page !!!
