Click Events Don't Work After LinkButton Postbackurl

I have a page with a linkbutton that has it's postbackurl pointing to a page that opens a excel
spreadsheet. The spreadsheet works fine but none of the click events work after the spreadsheet is opened. Here's the code for the page tha opens the spreadsheet.

<%@ Page Title="" Language="VB" MasterPageFile="~/Master Pages/Sponsor Program.master" AutoEventWireup="false" CodeFile="Print Excel.aspx.vb" Inherits="Chairman_Sponsor_Program_Reports_Print_Excel" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
   
</asp:Content>

Here is the vb code behind

Partial Class Chairman_Sponsor_Program_Reports_Print_Excel
    Inherits System.Web.UI.Page
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        'CType(Page.PreviousPage, MyPreviousPage).MyPublicMethod()
        Dim fileData() As Byte = System.IO.File.ReadAllBytes(Server.MapPath("~/temp/sponsorsexport.xls"))

        Response.Clear()
        Response.AddHeader("Content-Type", "application/vnd.ms-excel")
        Response.AddHeader("Content-Disposition", "attachment; filename=""sponsorsexport.xls""")
        Response.BinaryWrite(fileData)
        Response.Flush()
        Response.End()

    End Sub

End Class
