Activating last textbox in DataGridView on form active

[AndrusM]

How to activate last textbox in DataGridView on re-activate ? I created testcase for it: 1. Run code. 2. Enter some data to grid 3. Click other form caption 4. Click original form caption 5. Enter some characters Observed: entered characters are ignored Expected: entered characters must appear in last cell before form activation How to fix ?

using System.Windows.Forms;

public class Test
{
static void Main()
{
Application.Run(new MainForm());
}
}

class MainForm : Form
{
public MainForm()
{
WindowState = FormWindowState.Maximized;
IsMdiContainer = true;
Form frm = new Childform();
frm.MdiParent = this;
frm.Show();
Form frm2 = new Childform();
frm2.MdiParent = this;
frm2.Show();
frm2.Left = 2000;
}
}

class Childform : Form
{
public Childform()
{
var grid = new DataGridView();
grid.Columns.Add(new DataGridViewTextBoxColumn());
grid.EditMode = DataGridViewEditMode.EditOnEnter;
Controls.Add(grid);
}
}
