Disabling the paste function in a text field

[EventeReporting]

I am creating a PDF form and am wanting to restrict the user so they cannot paste text from another source into a text field on the form.  Is this possible?

I am using Acrobat Pro DC.

Thanks.

In a keystroke script you can reject anything that's more than a single character, as would happen if multiple characters were pasted. This would still allow the user to paste a single character at a time. Would that be OK?

If that is something I can setup easily that would be fine.

Thanks.

The custom keystroke script (Text Field Properties dialog > Format tab > Custom format category > Custom Keystroke Script) can be as simple as:

event.rc = event.change.length < 2;

The problem is if you need to do this for fields that use one of the built-in formatting categories (e.g., Number or Date), then it gets more complicated.

Thank you very much.  That works fine for what I need to do.

Awesome - thank you 🙂

I see how this works, but when I tried on my document I found that I could only access the format tab when a single field is selected. Is there a way to do this for an entire document at once, or at least an entire page at once?

Yes, you can write a console script to apply the custom keystroke to a whole set of fields all at once.
