Why this code failed to access label inside a repeater ?

I  have a repeater on the aspx page successfully get database value and listed in HTML
 <asp:Repeater ID="Repeater1" runat="server" DataSourceID="AccessDataSource2"         onitemdatabound="Repeater1_ItemDataBound"> <ItemTemplate> <asp:Label ID="Label2" runat="server" Text="">'<%#DataBinder.Eval(Container.DataItem, "DDL2")%>',</asp:Label>     </ItemTemplate></asp:Repeater>
Now I want this same text to get into label1.text for further use. So I used this
 Protected Sub Repeater1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs)         Dim Label2 As Label = e.Item.FindControl("Label2")         Label1.Text = Label2.Text ...
