Page.FindControl non-Shared member

[tshad]

I have a .ascx file that I converted to a class.

But I am getting the following error:

error BC30469: Reference to a non-shared member requires an object
reference.

The error is for the Page.FindControl in the following code:

******************************************

Imports System.Web.UI.WebControls
Imports System.Web.SessionState

Imports System.Web.HttpApplication

Imports System.Collections

NameSpace MyFunctions

Public Class PageInit

Public Shared sub PageSetup ()
Dim UserLoggedOn as Label = CType(Page.FindControl("UserLoggedOn"),Label)
Dim UserLoggedOnLabel as Label =
CType(Page.FindControl("UserLoggedOnLabel"),Label)
if not UserLoggedOn is nothing then
if HttpContext.Current.session("LoggedIn") <> nothing then
if HttpContext.Current.session("firstName") <> nothing then
UserLoggedOn.Text = UserLoggedOn.Text &
HttpContext.Current.session("firstName")
if HttpContext.Current.session("lastName") <> nothing then
UserLoggedOn.Text = UserLoggedOn.Text & " " &
HttpContext.Current.session("lastName")
end if
end if
if not UserLoggedOn is nothing then
UserLoggedOn.visible = true
if not UserLoggedOnLabel is nothing then UserLoggedOnLabel.visible =
true
end if
end if
end if
if not HttpContext.Current.session("User") is nothing then _
HttpContext.Current.session("LastPageVisited") =
HttpContext.Current.Session("User").LastPageVisited
End Sub
End Class
End Namespace
*************************************************************************

Why am I getting this error?

Do I need something in front the Page.FindControl?

Thanks,

Tom

Page is a class. It is not an instance of that class. You should pass in a
variable to your PageSetup routine, which is an instance of the page it
should set up.

In a .ascx, Page is a property of the class, hence you can use it. When you
are just in a function in some other class, it doesn't have such a property.

Would I then do the following in the function:
**************************************************************
NameSpace MyFunctions

Public Class PageInit

Public Shared sub PageSetup (thePage as Page)
Dim UserLoggedOn as Label =
CType(thePage.FindControl("UserLoggedOn"),Label)
Dim UserLoggedOnLabel as Label =
CType(thePage.FindControl("UserLoggedOnLabel"),Label)
***********************************************************************

And then call it as:

MyFunctions.PageInit.PageSetup(Page)

Here is how I set it up and it works great.

****************************************
NameSpace MyFunctions

Public Class PageInit

Public Shared sub PageSetup (thePage as Page)
Dim url as String
Dim urlNoParams as String
Dim UserLoggedOn as Label =
CType(thePage.FindControl("UserLoggedOn"),Label)
Dim UserLoggedOnLabel as Label =
CType(thePage.FindControl("UserLoggedOnLabel"),Label)
if not UserLoggedOn is nothing then
if HttpContext.Current.session("LoggedIn") <> nothing then
if HttpContext.Current.session("firstName") <> nothing then

*******************************************************

I call it like so:

<%@ Import Namespace="MyFunctions" %>

<script runat="server">
Sub Page_Load(sender as Object, e as EventArgs)
if not IsPostBack
PageInit.PageSetup(Page)

Why do I need to send it the "Page" but not the Session Variables? Isn't
there a direct way to access it as the current Page?

Thanks,

Tom
