ok, my fault....
now here my code:

                // Call this method in form's ctor
                private void InitBW()
                {
                        mBW = new BackgroundWorker(this);
                        mBW.RunWorkerCompleted += new
RunWorkerCompletedEventHandler(mBW_RunWorkerCompleted);
                        mBW.ProgressChanged += new
ProgressChangedEventHandler(mBW_ProgressChanged);
                        mBW.DoWork += new DoWorkEventHandler(mBW_DoWork);
                        mBW.WorkerReportsProgress = true;
                        mBW.WorkerSupportsCancellation = true;
                }

                // Completion event
                private void mBW_RunWorkerCompleted(object sender,
RunWorkerCompletedEventArgs e)
                {
                        this.pgBar.Hide();
                        
                }

                // Progress event
                private void mBW_ProgressChanged(object sender,
ProgressChangedEventArgs e)
                {
                        this.pgBar.BringToFront();
                        this.pgBar.Value = e.ProgressPercentage;
                }

                // On worker thread! Only method with real logic
                private void mBW_DoWork(object sender, DoWorkEventArgs e)
                {
                        this.refreshView();
                }

                /// <summary>
                /// manage the click on the TYP button
                /// </summary>
                /// <param name="sender"></param>
                /// <param name="e"></param>
                private void bTYP_Click(object sender, EventArgs e)
                {
                        this.activeCategory = "TYP";
                        this.resetActiveCategory();
                        this.BackColor = Preferences.COLOR_CATEGORY_TYP;
                        this.refreshView();

                }

the method refreshView handles some stuff to load data and managa the gui...
whats wrong?
