Image show on Picturebox only on debug again. I made a windows form for images but images shows only on second time debuging on pic box

private void toolStripButton1_Click(object sender, EventArgs e)
        {
            // open file dialog
            OpenFileDialog open = new OpenFileDialog();

            // image filters
            open.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp";
            open.FilterIndex = 2;
            if (open.ShowDialog() == DialogResult.OK)
            {
                

                using (SqlCeCommand cmd = new SqlCeCommand("INSERT into imag(image)VALUES(@image)", con))
                {
                    Stream fileStream = open.OpenFile();

                    
                    fileStream.CopyTo(ms);
                    byte[] a = ms.GetBuffer();

                    cmd.Parameters.Clear();
                    cmd.Parameters.AddWithValue("@image", a);

                    cmd.ExecuteNonQuery();
                  
                    this.imagTableAdapter.Fill(this.bb1DataSet.imag);
                    this.imagBindingSource.MoveLast();
                   
                }
