在datagridview的单元格中输入数据后触发什么事件

Question

As the title suggests what event gets fired when the user has entered text in a cell. I wan't to use this event for handling some validation.

So far i am using CellValidating event but the problem with it is that it also gets called whenever the user clicks in the cell. Where as i want an event that only gets called once the data has been entered so i can perform validation.

private void totalPurchaseDataGridView_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
    {
        if (e.ColumnIndex==0)
        {
            SqlDataAdapter ad = new SqlDataAdapter(@"SELECT id from Customer", connection);
            DataTable dt = new DataTable();
            ad.Fill(dt);
            int value = int.Parse(e.FormattedValue.ToString());
            DataRow[] dr = dt.Select("id = " + value);
            if (!dr.Any())
            {
                totalPurchaseDataGridView.Rows[e.RowIndex].ErrorText = "Foreign key problem";
                e.Cancel = true;
            }
            Form2 second = new Form2();
            this.AddOwnedForm(second);
            second.Show();
        }
    }

Try datagridview cellendedit event

private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
    if (e.ColumnIndex==0)
       {
        SqlDataAdapter ad = new SqlDataAdapter(@"SELECT id from Customer", connection);
        DataTable dt = new DataTable();
        ad.Fill(dt);
        int value = int.Parse(e.FormattedValue.ToString());
        DataRow[] dr = dt.Select("id = " + value);
        if (!dr.Any())
        {
              message.show("Foreign key problem");
         }
        else {
        Form2 second = new Form2();
        this.AddOwnedForm(second);
        second.Show();
         }
        }
