Show button and then download file doesn't work..

[max]

Hi I've a little problem when I show a button from an Ajaxified control and then I use the button to download a file, I've also tried to register the control but it won't work..

this is the code:

    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>

    <div>
        <asp:Button ID="Button1" runat="server" Text="Show" />
        <asp:Button ID="Button2" runat="server" Text="Download" Visible="false" />
    </div>

    <telerik:radajaxmanager ID="Radajaxmanager1" runat="server" >
        <AjaxSettings>
            <Telerik:AjaxSetting AjaxControlID="Button1">
                <UpdatedControls>
                    <Telerik:AjaxUpdatedControl ControlID="Button2" />
                </UpdatedControls>
            </Telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:radajaxmanager>

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Button2.Visible = True
        ScriptManager1.RegisterPostBackControl(Button2)
    End Sub

    Private Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click

        Dim fi As New System.IO.FileInfo("C:\test.zip")

        If fi.Exists Then

            HttpContext.Current.Response.Buffer = True
            HttpContext.Current.Response.ClearContent()
            HttpContext.Current.Response.ClearHeaders()
            HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + fi.Name)
            HttpContext.Current.Response.ContentType = "application/download"
            HttpContext.Current.Response.AddHeader("Content-Length", fi.Length)
            HttpContext.Current.Response.WriteFile(fi.FullName)
            HttpContext.Current.Response.End()
            HttpContext.Current.Response.Flush()

        End If

    End Sub

Thank you for reply,
it could be a partial solution because my goal is to download the file.
The browser, instead, open directly files like pdf, doc, jpg, xls, etc.
