サンプルコード

using System;
using System.CodeDom;
using System.CodeDom.Compiler;
using System.Reflection;
using System.Windows.Forms;
using System.Drawing;
using System.Data.OleDb;
using System.Data;

class form1: Form {
	DataGridView dataGrid1;
	TextBox bo1 = new TextBox();
	form1() {
		Text = "DataGridView";
		ClientSize = new Size(500, 300);
		dataGrid1 = new DataGridView();
		dataGrid1.Location = new Point(50, 50);
		dataGrid1.Width = 400;
		ClientSize = new Size(600, 400);
		bo1.Location = new Point(150, 20);
		Controls.AddRange(new Control[] {
			bo1,
			dataGrid1
		});
		dataGrid1.ColumnCount = 3;
		dataGrid1.Columns[0].HeaderText = "ID";
		dataGrid1.Columns[1].HeaderText = "商品";
		dataGrid1.Columns[2].HeaderText = "個数";
		dataGrid1.Rows.Add(new Object[] {1, "みかん", 100});
		dataGrid1.Rows.Add(new Object[] {2, "りんご", 300});
		dataGrid1.Rows.Add(new Object[] {3, "バナナ", 200});
		dataGrid1.Rows.Add(new Object[] {4, "すいか", 300});
		dataGrid1.Rows.Add(new Object[] {5, "いちご", 200});
		dataGrid1.Rows.Add(new Object[] {6, "メロン", 100});
		dataGrid1.CellEnter += new DataGridViewCellEventHandler(dgvControl_CellEnter);
	}
	void dgvControl_CellEnter(object sender, DataGridViewCellEventArgs e) {
		DataGridView grid = sender as DataGridView;
		Console.WriteLine(grid[e.ColumnIndex, e.RowIndex].Value.ToString());
		bo1.Text = grid[e.ColumnIndex, e.RowIndex].Value.ToString();
	}
	[STAThread]
	public static void Main() {
		Application.Run(new form1());
	}
}

以上。
