2.0: inaccessible control in DataList

[RAM]

Hi,
Please help again.
I have written DataList control with editing/deleting/adding rows - in .aspx
I have:
<aspataList ID="PositionsDataList" runat="server"

OnEditCommand="Positions_Edit"

OnUpdateCommand="Positions_Update"

OnCancelCommand="Positions_Cancel"

OnDeleteCommand="Positions_Delete"> ...

<FooterTemplate>

</tbody>

<tfoot>

<tr><td><asp:LinkButton ID="PositionsAdd" runat="server" Text="Add"
CommandName="Add" OnCommand="Positions_Add" /></td> ...

It works genarally fine. I have a problem with switching off Add button in
Positions_Add function (I want disable the control and go to edit mode of a
new row):
protected void Positions_Add(object sender, CommandEventArgs e)

{

PositionsDataList.EditItemIndex = PositionsDataList.Items.Count;

PositionsBind(connection, true);

((LinkButton)PositionsDataList.FindControl("PositionsAdd")).Visible =
false;

}

There's an error in last line because FindControl returns null. I don't
understand why and I don't know how to write the code correctly.
Please help. Thanks.

LinkButton button = (LinkButton)
PositionsDataList.Controls[PositionsDataList.Controls.Count -
1].FindControl("PositionsAdd")
