Query Notifications

Question

Well, basically this is the problem.
First, I couldn't get it to work (database moved from another computer - owner issues - solved), now I can't get it to stop.

I have a table called birouri and I want to let's say update all the datagridviews of the clients where there's a change in the table.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Data.Sql;

using System.Data.SqlClient;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using System.Security.Permissions;

namespace TicheteC

{

    public partial class formBirouri : Form

    {

        private SqlCommand mCommand;

        private string mSqlConnectString;

        private int mChangeCount;

        #region Permisiuni

        private static bool CanRequestNotifications()

        {

            try

            {

                SqlClientPermission perm = new SqlClientPermission(PermissionState.Unrestricted);

                perm.Demand();

                return true;

            }

            catch

            {

                return false;

            }

        }        

        private void GetData()

        {

            this.ticheteDataSet.Clear();

            mCommand = this.birouriTableAdapter.SelectCommand;

            mCommand.Notification = null;

            SqlDependency dependency;

            dependency = new SqlDependency(mCommand);

            dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);

            this.birouriTableAdapter.Fill(this.ticheteDataSet.birouri);

            InfotoolStripStatusLabel.Text = String.Format("{0} change(s).", mChangeCount);

        }

        #endregion

        public formBirouri()

        {

            InitializeComponent();

        }

       private void Birouri_Load(object sender, EventArgs e)

        {

            if (CanRequestNotifications() == true)

            {

                mSqlConnectString = this.birouriTableAdapter.Connection.ConnectionString;

                SqlDependency.Stop(mSqlConnectString);

                SqlDependency.Start(mSqlConnectString);

                GetData();

            }

        }

        private void birouriBindingNavigatorSaveItem_Click(object sender, EventArgs e)

        {

            this.Validate();

            this.birouriBindingSource.EndEdit();

            this.birouriTableAdapter.Update(this.ticheteDataSet.birouri);

        }

        private void Birouri_FormClosed(object sender, FormClosedEventArgs e)

        {

            SqlDependency.Stop(mSqlConnectString);

        }

        private void dependency_OnChange(object sender, SqlNotificationEventArgs e)

        {

            ISynchronizeInvoke i = (ISynchronizeInvoke)this;

            if (i.InvokeRequired)

            {

                OnChangeEventHandler tempDelegate = new OnChangeEventHandler(dependency_OnChange);

                object[] args = { sender, e };

                i.BeginInvoke(tempDelegate, args);

                return;

            }

           SqlDependency dependency = (SqlDependency)sender;

           dependency.OnChange -= dependency_OnChange;

           ++mChangeCount;

           GetData();

        }

    }

}

The problem is that the datagridview keeps on updating. Can anyone see if there's something wrong with the code ?
