Is it possible that page_load procedure does not execute when we call a page from javascript ??

 I have a page called searchjob.aspx ( which is pop up window to be precise)
 From searchjob.aspx's javascript procedure I am calling another page called showjob.aspx using following code
<script runat="server">
    Protected Sub btnsearch_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim str(9) As String
        Dim i As Integer
        For i = 0 To ListBox1.Items.Count - 1
            If ListBox1.Items(i).Selected = True Then
                str(i) = ListBox1.Items(i).Value
                Response.Write("" + str(i))
     &nbs ...
