display the output from method on a label

I have created a method in BLL and try to execute it when the use click the submit button.


I am trying to display the result of method on a label : i.e you have generated a new ticket sucessfully : Ticket number 4009. how can I display the output on a labe control?

result =   Add.AddNewTicket(create_date, callbackinfo, clinic_id, requestor, status_id, priority_id, issuetype_id, agent_id, issuedesc, RequestMethod_ID, followup, Log);

--Here is a method in BLL

  public  void  AddNewTicket(DateTime create_date, string callbackinfo, int clinic_id, string requestor, int status_id, int priority_ID, int issuetype_id, int agent_id, string issuedesc, int RequestMethod_ID, DateTime followup, string log)
        {
            Ticket_HeaderTableAdapter AddNewTicket = new Ticket_HeaderTableAdapter();

            try
            {
                AddNewTicket.FillAddNewTicket(create_date, callbackinfo, clinic_id, requestor, status_id, priority_ID, issuetype_id, agent_id, issuedesc, RequestMethod_ID, followup, log);

            }

            catch (Exception ex)
            {
            }
        }


--Here is the code behind

protected void Submit_Click(object sender, EventArgs e)
    {

        TicketBLL Add = new TicketBLL();

        string result;
        DateTime  create_date = Convert.ToDateTime(Label1.Text);
        string callbackinfo = TextBox2.Text;
        int clinic_id =  Convert.ToInt32(DropDownList1.SelectedValue);
        string requestor = TextBox1.Text;
        int status_id = Convert.ToInt32(DropDownList11.SelectedValue);
        int priority_id = Convert.ToInt32(DropDownList3.SelectedValue);
        int issuetype_id = Convert.ToInt32(DropDownList7.SelectedValue);
        int agent_id = Convert.ToInt32(DropDownList2.SelectedValue);
        string issuedesc = TextBox4.Text;
        int RequestMethod_ID = Convert.ToInt32(DropDownList6.SelectedValue);
        DateTime followup = Convert.ToDateTime(CompletionDate.Text);
        string Log = TextBox6.Text;

        Add.AddNewTicket(create_date, callbackinfo, clinic_id, requestor, status_id, priority_id, issuetype_id, agent_id, issuedesc, RequestMethod_ID, followup, Log);

       
}
