I have found no event that can handle the value of cell change properly.

I am also adding the code here:

void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)

{

   if (dataGridView1.CurrentCell.ColumnIndex == 0)
   {

      TextBox tb = (TextBox)e.Control;
      tb.TextChanged += new EventHandler(tb_TextChanged);
   }
}

void tb_TextChanged(object sender, EventArgs 
{
   MessageBox.Show("changed");
}
