Accessing the original value of value within an editor validator

yet

We have a use case where I need to retrieve the original (numeric) value of an editor field for validation purposes.
The changed value of the value must be in the range 0..<original value>. So I need to get hold of the original value of
particular editor cell?

I'm not quite sure what you mean I'm afraid. The data submitted to the server should be numeric and not formatted into something else (unless you have a formatter on it of some sort?).

See

https://s.nimbus.everhelper.me/share/1232540/l91mp5yz9ykxzrw4qh0v

This row has a current value of "10" (L).

The user is able to edit this row:

https://s.nimbus.everhelper.me/share/1232545/ith3n0voa3vu5zanslaf

The user can enter arbitrary values (I already have a validator). The validator must in this case validate the value for being greater of equal to zero and the value must be less or equal the current value to 10.

Attach a function to the editor open event that makes a copy of the original value in the field. Then on the preSubmit you can compare the current value to the original.
