How to prevent uncheck of preselect records in multiselect lookup?
I have a multiselect detail and I have added code to mark already selected records when the lookup window is opened again. For example if A, B are already added to the multiselect, when user wants to add C,D, E, the records A & B will already be checked.
There are multiple validations done before we add a record. Unchecking of already added records will cause complication.
We see preventing uncheck of values as a solution. Is there a way to prevent uncheck of records?
