Forms Data Controls :: Connect A Label Manually Placed Inside Formview By C#?

I have a addform where I maually have placed a confirm label inside the formvieww.

But how can I connect this label with C# ??

If I place the label Outside the addform, I can connect the label, but I can't find the label if it is placed inside the formview.

This is my code down here for the outside label, which do well.

<asp:Label ID="lblreceipted" Text=" " runat="server"></asp:Label>
<asp:FormView ID="AddForm" OnItemInserted = "FormViewAddNew_Inserted" ...
protected void FormViewAddNew_Inserted(object sender, FormViewInsertedEventArgs e)
{
System.Threading.Thread.Sleep(1000);
if (e.Exception == null)
{
lblreceipted.Text = "your insert succes";
}
}
