referencing the page from a control

[DC Gringo]

I have an myPage.aspx with a myPage.ascx user control. The user control is
the main header of the page. I have some conditional case code in the user
control that I use which depends on a public variable "sectionID" set int he
myPage.aspx's code-behind. How can I reference that variable in my control
dynamically? I can hard card in the name of the myPage.aspx.vb class but
that doesn't help me if the control is used within many different pages.

---------------------------------------------------
In my myPage.aspx.vb, I have:

Public sectionID As String = "home"


---------------------------------------------------
In my myPage.ascx, I have:
Public Sub theSectionID()

Select Case <WHAT GOES HERE???>.sectio nID
Case "home"
sectionHeaderLa bel.Text = "Welcome section"
Case "about"
sectionHeaderLa bel.Text = "Another section"
Case Else
sectionHeaderLa bel.Text = "Error"
End Select

End Sub

You would need to cast the Page property of the user control, to the type of
your Page (whatever that name is). This means you would need a reference to
the assembly that contains your page in the project for the user control (if
they are separate project0> Once you have a variable of the right type
pointing to the page, the sectionID variable should be available since it is
public.

Another way to do this, is to use reflection on the Page property of the
user control, look for a member called 'sectionID', and then
programmaticall y retrieve its value. This is kind of messy.

The best solution, would probably to expose a method or property on your
user control, that the page can call to pass in the sectionID. The user
control would store it for later access.

Either that, or have that be a parameter to theSectionID method, if the page
is doing the calling.

I'm trying to expose a method on the user control and pass in the sectionID.
It's not working and I get error: "Argument not specified for parameter
'sectionID' of 'Public Sub theSectionID(se ctionID As String)'."

What I have is:
myPage.aspx has:
--------------------------
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
Dim sectionID As String
sectionID = "home"
mainHeader1.the SectionID(secti onID)
End Sub

myPage.ascx has:
--------------------------
Public Sub theSectionID(By Val sectionID As String)
Select Case sectionID
Case "home"
sectionHeaderLa bel.Text = "Welcome"
Case "about"
sectionHeaderLa bel.Text = "About"
Case Else
sectionHeaderLa bel.Text = "Error"
End Select
End Sub

You can have a public function or sub in myPage.ascx which is called during
the page_load event of the hosting page. Pass it the value there, or if you
want it to have more access, pass it the page.
