How can i retain checkbox in parent ?

Hello,

How can i retain checkbox in parent, I have picklist in child containing ('a','b','c','d','e'). I created a child with a picklist of 'a' and it should checked on parent and i delete the child, the checkbox 'a' of parent should be uncheked  . the main problem is if i created another child that contains picklist 'a', and i delete the first child which is picklist 'a' the checkbox of parent will retain because there is another child that i created with picklist 'a' . how can i create a trigger for that?

Thanks for help!

Hey Arnold, This feature can be achieved using Apex Triggers on your child object. You would need to add logic to run on insert / update / delete / undelete events.

Hi Arnold,

Can you confirm one thing like you want only one check box for pick list a or 5 check box for a,b,c,d,e   .Please confirm .

Hi Arnold ,

Below trigger will work for checkbox A and picklist A ,Try to implement for next four .

trigger ParentCheckBox on Child (After insert ,After update,After delete ,After undelete) {
  Map<id,String> idpicklistvalueMap=new Map<Id,String>();
   if(Trigger.isInsert || Trigger.isUpdate || Trigger.isUndelete){
  for(Child chd : Trigger.new){
    if(chd.ChildChekbox__c != null){
     idpicklistvalueMap.put(chd.AccountId,chd.ChildChekbox__c);
    }
    }
   }if(Trigger.isDelete){
 for(Child chd : Trigger.old){
    if(chd.ChildChekbox__c != null){
     idpicklistvalueMap.put(chd.AccountId,chd.ChildChekbox__c);
    }
    }
   }
  
   List<Parent> patListToUpdate=new List<Parent>();
   for(Parent pat :[SELECT id,(SELECT ChildChekbox__c FROM Contacts WHERE ChildChekbox__c='A') FROM Parent WHERE id IN : idpicklistvalueMap.keySet()]){
      if(pat.ChildRelationshipName.size() > 0){
         Parent prt=new Parent(id=pat.Id,ParentChkBox__c=true);
            patListToUpdate.add(prt);
      }else{
         Parent prtt=new Parent(id=prtt.Id,ParentChkBox__c=false);
             patListToUpdate.add(prtt);
      }
   }
   try{
     update patListToUpdate;
   }catch(DMLEXception de){
      System.debug(de);
   }
}

Any issue let me know .

Hey Arnold ,

Do one thing in all cases just pass the account id set from trigger to handler class method  ,and apply the logic .

 
ManojjenaManojjena
Arnold ,
try below code it will work , 
trigger ContractCheckBox on Sample_Program__c (After insert ,After update,After delete ,After undelete) { 
	   Set<Id> contractIds=new Set<Id>();
	   if(Trigger.isInsert || Trigger.isUpdate || Trigger.isUndelete){
			for(Sample_Program__c sp : Trigger.new){
			  if(sp.Method_Type__c != null){
				 contractIds.add(sp.Contract_ID__c);
			  }
		   }
	   }if(Trigger.isDelete){
		for(Sample_Program__c sp : Trigger.old){
			  if(sp.Method_Type__c != null){
				  contractIds.add(sp.Contract_ID__c);
			  }
		   }
	   }
	List<Contract> cont = [SELECT Id, Composite__c, Dioxin__c, Metal_Scan__c, Grab__c, Organic_Scan__c,( SELECT Method_Type__c FROM Sample_Programs__r )FROM Contract WHERE Id IN: contractIds];
    for(Contract cnt: cont){
		if(cnt.Sample_Programs__r != Null){
			for(Sample_Program__c sampleRec: cnt.Sample_Programs__r){
				if(sampleRec.Method_Type__c == 'Grab'){
					cnt.Grab__c = true;
				}else if(sampleRec.Method_Type__c == 'Composite'){
					cnt.Composite__c = true;
				}else if(sampleRec.Method_Type__c == 'Metal Scan'){
					cnt.Metal_Scan__c = true;
				}else if(sampleRec.Method_Type__c == 'Dioxin'){
					cnt.Dioxin__c = true;
				}else if(sampleRec.Method_Type__c == 'Organic Scan'){
					cnt.Organic_Scan__c = true;
				}
			}
		}
	}
	try{
		update cont;
	}catch(DMLException de ){
	    System.debug('*******'+de);
	}
}
