UPDATE TWO TABLES using ONE UPDATE COMMAND IN GRIDVIEW SQL DATASOURCE

Hi, I'm trying to update two tables using the UPDATE command in gridview using SQL Datasource. Here's my current code, but when I run it, nothing happens when I update the table.

<asp:SqlDataSource ID="SqlDataSource4" runat="server" 
                    ConnectionString="<%$ ConnectionStrings:HelpDeskDB %>"
                    SelectCommand="SELECT ticket_no, ticket_status, thread, date_created, last_update, name FROM aspnet_Ticket WHERE (ticket_status = 'PENDING') OR (ticket_status = 'ON-PROCESS')"
                   UpdateCommand="
                    UPDATE aspnet_Ticket SET
                    ticket_no = aspnet_Operation.ticket_no,
                    ticket_status = aspnet_Operation.ticket_status
                    FROM aspnet_Ticket
                    INNER JOIN aspnet_Operation
                    ON aspnet_Operation.ticket_no = aspnet_Ticket.ticket_no
                    WHERE aspnet_Operation.ticket_no = aspnet_Ticket.ticket_no">
                        <UpdateParameters>
                            <asp:Parameter Name="ticket_status" />
                        </UpdateParameters></asp:SqlDataSource>
