After attempts, I am posting this question. If anyone could contribute and give a solution, it would be of great help.
There is a doctype named (Parent) and in this doctype, I have given the link to connect with the child table. In child Table, I have a select column (status) for 4 different values (eg:- ‘a’,‘b’,‘c’,‘d’) and other columns.
Now, on the loading of a parent, also on the selection of child table select column (status) (eg:- ‘a’), I want to keep other columns read-only on that particular row only (Not on the whole table).
Hope you all get my question!
