Not to change the record

[Khushalay]

Hi friends

I have a form where a particular field is required not to be edited once data is entered into it. It means user can enter the data for the first time but after that, he cannot edit/change it.

I know about record lock property but that locks the field to enter the data even for the first time. What else can be done for this?

Thanks in advance.

use conditional formatting

Expression Is ....Not IsNull([controlname])
and set the format to disabled
