How to disable dots on Kendo UI NumericTextBox?

Question

I need to make a numeric field only integer, so that the field does not accept decimals. I would not even like the field to approximate, simply not accepting points or commas.

Based on the culture, it accepts the numeric separator (eg EN is the point, IT is the comma)

Here is the code I tried

$("#numerictextbox").kendoNumericTextBox({
     culture: "en-US",
     step: 500,
     spinners: false,
     format: "#",
     decimals: 0
});

Here you can find the link to dojo with the example of Italian culture, in this case it blocks the comma

Have you tried changing the format to "{0:n0}"? You can also try "{0:#.##}" if you find that "{0:n0}" doesn't always get rid of the decimal separator. — Daniel Attfield, Oct 28 '19 at 10:23
They eliminate the decimal separator, but the problem remains. I would not like the new value to be approximated (eg 3.9 becomes 4) — i.signori, Oct 28 '19 at 10:32
I wouldn't want them to be able to add it, now as you can try in the examples, it's possible. But I would like to have only integer number, if possible not let the user to insert a separator. — i.signori, Oct 28 '19 at 10:41

Try using the restrictDecimals configuration option.

$("#numerictextbox").kendoNumericTextBox({
    culture: "en-US",
    step: 500,
    spinners: false,
    format: "#",
    decimals: 0,
    restrictDecimals: true
});

With this configuration a comma and a point with behave like entering a letter(red exclamation flash).
