Hi Tillu,

Please write following code on Setup>Customize>Cases>Case Comments then Trigger path.
  • trigger validation on CaseComment (before update, before delete) {  
  •     if(Trigger.isUpdate){
  •         for(CaseComment caseCmt : Trigger.new){       
  •             caseCmt.addError('You can not Update Case Comment.');
  •         }
  •     }
  •     else{
  •         for(CaseComment caseCmt : Trigger.old){       
  •             caseCmt.addError('You can not Delete Case Comment.');
  •         }
  •        
  •     }
  • }

Hope its solves you problem... :)

HI Tillu,

"Case Comment" is child object of Case,
i think we cannot write Validation rule for Case Comment but we can write Triiger for your Requirment.

Thanks

You Should write trigger on Case Comment under Setup>Customize>Cases>Case Comments then Trigger,
and events should be before Update and before delete.

Hope it helps...;)

hello. Thank you for the code. It works for all users. In cases when the trigger should execute allowing one or two users to update or delete comments, how would the code look?
