ListBox problem

[ttkalec1]

I have this situation. I wrote some code and it works just fine when I run it locally on my Visual Studio server, but when I send it to my web site, it doesn't work.

The code looks like this:

    Protected Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles ListBox1.SelectedIndexChanged
        ListBox2.Items.Clear()
        If ListBox1.SelectedItem.Text = "ab" Then
            ListBox2.Items.Add("aaaabbb")
            ListBox2.Items.Add("aaacccc")
            ListBox2.Items.Add("aaadddd")
        End If
End Sub

It's pretty simple. it populates a second listbox with some values when I click on an item in listbox1.
AutoPostBack is set to True on my listboxes and I have enabled ViewStates for my listboxes.
ListBox1 comes with predefined items, but when I click on of that items nothing happens if I run it on my website.
What could be the problem?

I figured out what was the cause of my problem. I haven't properly build my application before deploying it to my a website.
