How to make thousand and decimal separator in textbox

It’s easy to implement with Wisej.

This is a rough example that you need to adapt to your requirements in terms of format, filter, etc. I would create a derived class and manage it there:

this.textBox1.Filter = "[\\d,\\.]";

private void textBox1_Leave(object sender, System.EventArgs e)
{
  if (Decimal.TryParse(this.textBox1.Text, out decimal value))
     this.textBox1.Text = value.ToString("n");
}

Filter is  a regular expression filter (see regexp documentation). For the formatting refer to .NET formatting guide.

In some implementations I have seen apps that remove the formatting in the Enter event. It’s a matter of requirements.

Hi Nicky..
That’s how I did it, I hope it helps you…

nValor = Convert.ToDecimal(txtTotal.Text.ToString());
txtTotal.Text = nValor.ToString(“#,##0.00”);

Hi Nicky,

did you try using a MaskedTextBox ?
It should help you achieve what you want.
