Hi @Dissident26

I wouldn't consider it as a bug. All our built-in validators treat null or empty strings as valid. Only the values not in the correct format for the defined type are treated as invalid.

Hi @adrianszymanski89, thanks for answering.

Yes, I do understand that, and it's fine to check on falsy values. But in my opinion it's the matter of type, not the falsy values.
When you have a type validation on number | null it's not obvious that you would get a value of type string eventually.

You are right, @Dissident26. While checking the docs I did not find clear information on what we get.

We say at http://localhost:8080/docs/javascript-data-grid/keyboard-shortcuts/#selection-keyboard-shortcuts that

and in general, cleaning is rather setting up null, as in clear() method that we can test here https://jsfiddle.net/3r9sa28L/.

But then when you select a cell it is treated more like an action of a cell editor and there we put an empty string.

So maybe we could add an option to allow developers setting up what the clear should mean.
