Timer using web application

Question

I'm trying to use a Timer in my web application, but cant seem to make it work. Here is my code:

VB Code:

Public Class WebForm1 
    Inherits System.Web.UI.Page 

    Protected WithEvents Label1 As System.Web.UI.WebControls.Label 

    Private t As New System.Timers.Timer(2000) 

    Private Sub Page_Load(ByVal sender As Object, _ 
            ByVal e As System.EventArgs) Handles MyBase.Load 
        AddHandler t.Elapsed, AddressOf TimerFired 
        t.Enabled = True 

    End Sub 

    Public Sub TimerFired(ByVal sender As Object, _ 
        ByVal e As System.Timers.ElapsedEventArgs) 
            Label1.Text = Now 
    End Sub 
End Class

Here I'm trying to change the text of the label every 2 seconds.

Do you know the difference between server-side and client-side code? Once the page has been rendered and sent, the client won't know anything of further server-side processing. Also please make your code more readable. — Dennis Traub

I think you need to learn and study the fundamental difference between server and client code.

By the provided code I think you need to update a label every 2 seconds withe the current date-time. For partial rendering and update of a page (and much more!) there is AJAX, and related timer. Please take a look to this good example about, I think, your needs:
