I'm having no success with a bound label in a FormView. I want the label to display the date and time when a record is edited. I've tried the Item_Updated event but nothing happens to the label. Any thoughts?

Protected Sub FormView1_ItemUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewUpdatedEventArgs ) Handles FormView1.ItemUpdated
        Dim datetime As Date
        Dim DateLabel As Label
        DateLabel = CType(FormView1.Row.FindControl("DateLabel"), Label)
        datetime = Now()
        If DateLabel Is Nothing Then
            DateLabel = New Label
            DateLabel.Text = datetime.ToLongTimeString()
        Else
            DateLabel.Text = datetime.ToLongTimeString()
        End If

    End Sub

Even if I just set the DateLabel.Text= "Hello" in the event handler, the label doesn't change in the FormView. If the bound control is Null and I exclude the If Then statement in the code, there's not even a null exception error that's thrown, causing me to think that the event is not even firing. However, if I use the FormView1_DataBinding event, the label does get updated but with every databinding event of the FormView, even if an update has occurred or not. I have no clue.
