C# WinApp ผมรับค่า bindingSource มาจาก อีกฟอร์มเพื่อใช้งาน DataGridView แต่ DataGridView ไม่มีอะไรเกิดขึ้ิน

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            new Form2{bindingSource1 = this.typeGlassBindingSource}.ShowDialog();
        }
    }

public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();

        }
        public  BindingSource bindingSource1 = new BindingSource();
       public DataGridView dgv;

        private void Form2_Load(object sender, EventArgs e)
        {
            Text = " data list:" + bindingSource1.List.Count;

            dgv = new DataGridView
            {
                AutoGenerateColumns = false,
                ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize,
                DataSource = bindingSource1.DataSource,
                Dock = DockStyle.Fill,
                Name = "dataGridView1"
            };
            this.Controls.Add(this.dgv);
           // bindingSource1.ResetBindings(true);
          // dgv.Refresh();
        }
    }
