[SalesForce] how to prevent the related list records from Edit and Delete function

I have object called Carset.In Carset am having a field "Valid" checkbox.

If the checkbox is checked then i cannot edit or delete the related list record(Child object-Service)

for editing i have written the below validation rule.It's working.

  IF(Car_Set__r.valid__c,true,false)

But for delete how to handle it using validation rule ?

Since validation rule doesn't fire on delete of record. You need to go with a simple trigger approach to prevent deletion

trigger triggerName on CustomObject__c (before delete)
{
   for(CustomObject__c obj: Trigger.old)
   {
     if(obj.valid__c) 
     {
        obj.addError('You can not delete this record');
     }
   }
}

This worked for me:

<style type="text/css">
            th.actionColumn {display:none !important; visibility:hidden !important} 
            td.actionColumn {display:none !important; visibility:hidden !important} 
</style>

[SalesForce] Bypass validation rule on parent object while updating parent object from Child object trigger

The problem looks clear to me as you are facing a challenge with the small point in order of execution of salesforce.

To understand this you need to refer to order of execution in salesforce.

Triggers and Order of Execution

If you go to the link you'll find out in step 4 the custom validations are run once again after the before triggers which fails your logic.

STEP 4: Runs most system validation steps again, such as verifying that all required fields have a non-null value, and runs any user-defined validation rules. The only system validation that Salesforce doesn't run a second time (when the request comes from a standard UI edit page) is the enforcement of layout-specific rules.

To avoid the problem I would request you to not make the checkbox BypassCloseddateValRule, you created to bypass the validation rule to FALSE in the trigger.

You should do this change in a later step after which custom validations are not called, i.e. in STEP 7 (After Trigger) or STEP 11 (Workflow field Update).

Because custom validation rules will not be called after those steps.

STEP 12: If the record was updated with workflow field updates, fires before update triggers and after update triggers one more time (and only one more time), in addition to standard validations. Custom validation rules and duplicate rules are not run again.

I believe this will solve your problem. Let us know if you face any other challenge.

Thank You.
