trigger event after X seconds

I am developing an app for windows phone. My question is how can I trigger an event after 2 seconds?

    Private Sub btn1_Click(sender As Object, e As RoutedEventArgs) Handles btn1.Click
    Dim input As String = txtinput.Text
    Dim last As Char = input(input.Length - 1)
    If last = "A" Then
        Dim final As String = input.Substring(0, input.Length - 1) & "B"c
        txtinput.Text = final.

      'start timer here
      'trigger an event after 2 seconds

    ElseIf last = "B" Then
        Dim final As String = input.Substring(0, input.Length - 1) & "C"c
        Dim tmr As TimeSpan = TimeSpan.FromSeconds(2)
        txtinput.Text = final

      'start timer here
      'trigger an event after 2 seconds


    Else
        txtinput.Text = input + "A"
    End If

 End Sub

I am using Visual Basic as my language in developing this. Any help would be much appreciated.

declare dispatcherTimer inside the class

Dim WithEvents dt As System.Windows.Threading.DispatcherTimer

then create instance of dispatcherTimer whereever you want, set time span

dt = New System.Windows.Threading.DispatcherTimer()
dt.Interval = New TimeSpan(0, 0, 0, 0, 500) '' 500 Milliseconds
dt.Start()

and here is your handler

Private Sub dt_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles dt.Tick
    ' Do Stuff here.
End Sub

*converted code to VB from here, though I have not tested it..it may work for you..

Maybe I just don't know the environment because I have never programmed for phones in .Net, but what about:

System.Threading.Thread.Sleep(2000)

Hope this helps
