Page.FindControl("DataList1:_ctl0:TextBox3");

OR

private Control FindControlRecursive(Control root, string id)
{
    if (root.ID == id)
    {
        return root;
    }
    foreach (Control c in root.Controls)
    {
        Control t = FindControlRecursive(c, id);
        if (t != null)
        {
            return t;
        }
    }
    return null;
}
