vb.net passing variable from .aspx.vb to .aspx javascript variable

Question

How do I pass a variable defined in .aspx.vb to .aspx.

I've tried this in the .aspx.vb:

Partial Class show_zoos
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'database logic
Dim postcode As String = an.Postcode
 End Sub
End class

And this for priting it out in the .aspx:

var postcode = '<%=postcode%>'

I got the following error:

'postcode' is not declared. It may be inaccessible due to its protection level.

What am I doing wrong?

Answer 1

postcode needs to be min visibility Protected.

Public postcode As String
 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 postcode = "ABCD"
 End Sub

• Chris Haas: Just to be a little more clear, variables need to be declared at the class level, not the method level.
• KBBWrite: Thanks Chris Haas. I did mean that. Also the minimum visibility of the variables should be protected level too. Should not be private.
