ASP.net change header text of GridView template columns

Hi. I am trying to change the header text of template columns in a GridView in ASP.net using the following VB.net code but for some reason the
headers are not changing

    Private Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs) Handles GridView1.RowDataBound
        For i As Integer = 0 To UBound(arrDates)
            oColIndex = i + 2
            oTemplateColumn = "D" & CStr(i + 1)
            oEachDate = CDate(arrDates(i))
            oDate = oEachDate.ToString("dd MMM yyyy")
            Me.GridView1.Columns(oColIndex).Visible = True
            If e.Row.RowType = DataControlRowType.Header Then
                Me.GridView1.Columns(oColIndex).HeaderText = oDate
            End If
        End if
Ebd Sub

-- Not sure what this means.

You do not need to write this code inside gridview rowdatabound. You can write it after your code to gridview1.DataBind();

For i As Integer = 0 To UBound(arrDates)
            oColIndex = i + 2
            oTemplateColumn = "D" & CStr(i + 1)
            oEachDate = CDate(arrDates(i))
            oDate = oEachDate.ToString("dd MMM yyyy")
            Me.GridView1.Columns(oColIndex).Visible = True
            Me.GridView1.Columns(oColIndex).HeaderText = oDate
        End if
