Try using MaskedEditExtender, if you are using for web page.
A working example is below.

Hi, Vani
Thanks for your help, but it does not solve the problem. Because, the MaskedEditTexbox, limit the number of digit, thus i don't want it to be limited... and if your mask is "000 000", if you write "500 00_" is very different from "50 000" that should be seen.

I havetry the links on stackoverflow.com, it doesn't work.
when i write "txtMtCategorie.Text.ToString("#,##0", new System.Globalization.CultureInfo("fr-FR"));"
i have this error "Error 1 No overload for method 'ToString' takes 2 arguments "
....

hi Vani,

finally i have made it. Thanks, i was forced to do it this way:

private void txtMtCategorie_TextChanged(object sender, EventArgs e)
{
if (txtMtCategorie.Text != "")
{
int Mavaleur = int.Parse(txtMtCategorie.Text.ToString().Trim(), System.Globalization.NumberStyles.AllowThousands);

txtMtCategorie.Text = Mavaleur.ToString("#,##0", new System.Globalization.CultureInfo("fr-FR"));
}
}

It works! is that a good way to do it?
thanks
