Accessing form class control's reference in custom control class

I want to somehow pass the reference (from form1.cs class) and access the reference of datagridview1 which is used only in Form1.cs in my declaration of customdatagridview . The reason is that in every form of my windows application , there will be a new Datagridview (all with different names) , and their reference would be used for some purpose by this custom datagridview . Is it possible to do it . If not , what should be the alternative.

public partial class smartdatagridview : DataGridView
    {
        public smartdatagridview()
        {
            InitializeComponent();
        }
        private TextBox textBox;

        protected override void OnEnter(EventArgs e)
        {
            base.OnEnter(e);
            CurrentCell = this[0, 0]; 
            BeginEdit(true);
        }
        protected override void OnEditingControlShowing(DataGridViewEditingControlShowingEventArgs e)
        {
            base.OnEditingControlShowing(e);

            if (CurrentCell.ColumnIndex == 0 && e.Control is TextBox)
            {
                textBox = (TextBox)e.Control;
                textBox.TextChanged -= Text_Changed;
                textBox.KeyDown -= Key_down;
                textBox.Enter -= Key_Enter;
                textBox.TextChanged += Text_Changed;
                textBox.KeyDown += Key_down;
                textBox.Enter +=Key_Enter;
            }
            else
            {
                textBox = null;
            }
        }

        protected override void OnCellEndEdit(DataGridViewCellEventArgs e)
        {
            base.OnCellEndEdit(e);
            if (textBox != null)
            {
                textBox.TextChanged -= Text_Changed;
                textBox.KeyDown -= Key_down;
                textBox.Enter -= Key_Enter;
                textBox = null;
            }
            if (this.CurrentCell.ColumnIndex == 0)
            {
                if (dataGridView1.Rows.Count > 0)  ***// error*** 
                {
                    this.CurrentCell.Value = dataGridView1.SelectedRows[0].Cells[1].Value.ToString(); ***// error*** 
                    dataGridView1.Visible = false;  ***// error*** 
                }
            }
        }
