datagridview1_keypress does not working

Question

        private void dataGridView1_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (dataGridView1.CurrentCell.ColumnIndex == 5 || dataGridView1.CurrentCell.ColumnIndex == 10)
        {
            aTimer.Interval = 850;
            aTimer.Start();
            string pwd = "*";
            pass.Add(e.KeyChar);
            dataGridView1.CurrentCell.Value = pwd;
            dataGridView1.CurrentCell.Value = GridView1_PreRender1(dataGridView1.CurrentCell.Value.ToString());

        }
    }

I'm getting no error but at the runtime which ever grid cell I click and enter values KeyPress does not take any action and it's killing me. I'm too desperate, any help would be great.

The issue is related to the fact that once you start editing a cell's value, you're no longer within the DataGridView but within the "Editing Control" defined by the cell's owning column. For a DataGridViewTextBoxColumn this is a TextBox. You'll need to hook into the events of the editing control. The details of which are shared in another answer:
