Here is the solution ...

Binding bd = txtPublishYear.DataBindings.Add("Text", dataGridview.DataSource, "PublishYear", true, DataSourceUpdateMode.OnValidation, "", $"Năm {0}");
bd.Parse += new ConvertEventHandler(CurrencyStringToNumber);

...

private void CurrencyStringToNumber(object sender, ConvertEventArgs cevent)
        {
            if (cevent.DesiredType != typeof(Int16)) return;

            string result = Regex.Match(txtPublishYear.Text, @"\d+").Value;
            cevent.Value = int.Parse(result,NumberStyles.Currency, null);
        }
