Neither worked for me.  Here is my code.
<
asp:Content ID="Content1" ContentPlaceHolderID="fkhead" Runat="Server">
<script runat="server">
Public Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
Dim a As String = "This is other data"
pqriminadpaylbl.Text = a
pqrimincustlbl.Text = a
pqriminadpaylbl.Text = a
pqriminpcdevlbl.Text = a
pqriminpctoollbl.Text = a
pqriminsaleslbl.Text = a
pqriminspadeslbl.Text = a
pqriminspamatlbl.Text = a
pqrimintdamortlbl.Text = a
pqrimintdcclbl.Text = a
pqrimintddtlbl.Text = a
pqrimintdfclbl.Text = a
pqrimintucdeslbl.Text = a
pqrimintucdollarlbl.Text = a
pqrimintucmatlbl.Text = a
pqriminvolaslbl1.Text = a
pqriminvolaslbl2.Text = a
pqriminvolasyear1lbl1.Text = a
pqriminvolasyear1lbl2.Text = a
pqriminvolasyear1lbl3.Text = a
pqriminvolasyear1lbl4.Text = a
pqriminvolasyear1lbl5.Text = a
pqrimindislbl.Visible =
False
pqriminprevbtn.Visible =
False
pqriminnextbtn.Visible =
False
End If
End Sub
</script>
<style type="text/css">
.trest
.newStyle1
text-align: right;
.table
width: 100%;
.newStyle2
font-size: 20pt;
font-weight: bold;
text-decoration: underline;
text-align: center;
.tdparts2
font-size: 16pt;
font-weight: bold;
.tb25
width: 25%;
font-size: 9pt;
.tb20
width: 20%;
font-size: 9pt;
.tb40
width: 40%;
font-size: 9pt;
.tb30
width: 30%;
font-size: 9pt;
</style>
</
asp:Content>
It works fin, but the designer keeps craping out.  This was not happening until recently.  Not sure what is up with it.
