Trigger page load on click event in ASP

[benjatado]

I am stumped with trying to trigger a page load in a button click event. I would like to display a "processing" statement prior to a redirect using the code below.

If someone could let me know how to trigger the page load and make the processingtxt.Visible = true that would be super!

Here is my code...

    Protected Sub btnSend_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSend.Click
        Dim i As Integer
        Dim trackList As New ArrayList()

        Dim clicked_btnSend As Button = sender
     
        clicked_btnSend.Text = "Processing..."
        clicked_btnSend.Enabled = False

        processingtxt.Visible = True

        For Each item As ListItem In lbSelectedTracks.Items
            trackList.Add(item.Value)

        Next

        DataUtilities.UploadTracks(trackList)
        lbSelectedTracks.Items.Clear()


        For i = 0 To (gridTracks.Rows.Count - 1)
            Dim cb As CheckBox
            Dim sRow As String = ""

            cb = gridTracks.Rows(i).Cells(5).Controls(1)
            If cb.Checked = True Then cb.Checked = False
            Response.Redirect("confirm.aspx")



        Next


    End Sub

Thanks in advance!!
