How Can I restrict one update for specific field ?

[jay97]

Hello Guys,

I have Custome table called u_marks and its has field called  u_grades which is a string field

I want that that if someone updated u_grades then it was empty then no one can update u_grades values if it is got updated previously. how can I achieve this?

Hi @jay97 ,

Make it readonly using onLoad and OnCellEdit client scripts so that no-one can change the values.

Let me know if you need more inputs on how to write them.
