Can I cause Trigger to fire only before delete called from UI?

I currently have a "before delete" trigger on OpportunityLineItem which stops line item records from being deleted if certain conditions are met.

 

Is there a way use an if to say that if the delete call is coming from the API or is due to a delete on the parent Opportunity record, to ignore the steps in the trigger?  I'd only want the steps to execute if the trigger is called from a line item delete via the UI.

 

I thought I read this once somewhere, but after all my searching, I can't seem to find it. 

 

Anybody know?

 

Thanks!!

Usually you would solve this by surrounding your effective trigger code by if(Trigger.new.size() == 1) { // Triggercode }.

 

This assumes the API never is used for only 1 record at once.

What about a custom button (still labeled Delete) on the Opportunity Products related list or page layout. That button calls a Visualforce page that invokes Apex code to validate the delete is allowed and if so, performs the delete. Otherwise, the Visualforce page can display the proper notification message.
