How do I define a global/public variable in ASP.net?
Hi,
I have a public variable which i want it to be updated when user access the page first time, and i use "If Not Page.IsPostBack" to set it. This works fine.
However, i still want to retain this variabe on postback,,,,how can i do it? The public variable always reverted to it's default value that i set during declaration on postback.
See code below for the details.

Partial Class _Default
Inherits System.Web.UI.Page
Public strTest As String = "This is default setting"
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
strTest = "First time login"
Response.Write(strTest)
Else
Response.Write(strTest) 'I can NOT get the variable to be updated with "First time login" on postback
End If
End Sub
