Binding a textbox to a datagridviewtextboxcolumn?

Question

Is it possible, to bind (or similar) a standard textbox to display the contents (dynamically) of the selected cell within a datagridview textboxcolumn?

My goal is that when a cell within this column has it's value altered, the textbox.text is also changed, and when the user selects a cell then types something in this separate textbox the value is updating the datagridview textboxcolumns value on the fly.

Yes you may bind common dataSource to both TextBox and DataGridView.

public class Foo
{
  public string Item { get; set; }
}

private void Form2_Load(object sender, EventArgs e)
 {
  List<Foo> list = new List<Foo>()
      {
       new Foo() { Item="1" },
       new Foo() { Item="2" }
   };

  dataGridView1.DataSource = list;
  textBox1.DataBindings.Add("Text", list, "Item");
}
