Hi Patrick,
Use DataBinding for this. Bind the Text property of the TextBox to the =
Column you want to display. The code below demonstrates how to do this.=
DataGridView dataGridView1 =3D new DataGridView();
TextBox textBox1 =3D new TextBox();
protected override void OnLoad(EventArgs e)
{
this.Controls.Add(dataGridView1);
this.Controls.Add(textBox1);
textBox1.Location =3D new Point(dataGridView1.Width + 5, 0);
DataSet set =3D new DataSet();
set.Tables.Add(new DataTable());
set.Tables[0].Columns.Add("ID", typeof(System.Int32));
set.Tables[0].Columns.Add("Value", typeof(System.String));
DataRow row =3D set.Tables[0].NewRow();
row["ID"] =3D 1;
row["Value"] =3D "One";
set.Tables[0].Rows.Add(row);
row =3D set.Tables[0].NewRow();
row["ID"] =3D 2;
row["Value"] =3D "Two";
set.Tables[0].Rows.Add(row);
row =3D set.Tables[0].NewRow();
row["ID"] =3D 3;
row["Value"] =3D "Three";
set.Tables[0].Rows.Add(row);
dataGridView1.DataSource =3D set.Tables[0];
dataGridView1.Columns[0].Visible =3D false;
textBox1.DataBindings.Add("Text", set.Tables[0], "ID");
}

Happy coding!
