Hi,

in the ondatabound event you can figure out on which page you currently are. If it's the first page then state something like:

DataPager1.NextPreviousPagerField.ShowPreviousPageButton = false;

It could be that you need to perform a findcontrol to get to the nextpreviouspagerfield of DataPager1 before you can set this setting.

    Protected Sub DataPager1_PreRender(sender As Object, e As EventArgs)
        Dim DP1 As DataPager = CType(sender, DataPager)
        For Each c As Control In DP1.Controls
            For Each c2 As Control In c.Controls
                If TypeOf c2 Is Button Then
                    Dim btn As Button = CType(c2, Button)
                    If Not btn.Enabled Then
                        btn.Attributes("style") = "display:none;"
                    End If
                End If
            Next
        Next
    End Sub

    Protected Sub DataPager1_PreRender(sender As Object, e As EventArgs)
        Dim DP1 As DataPager = CType(sender, DataPager)
        For Each c As Control In DP1.Controls
