Customized Event Triggers

[sultan_mustun]

Hello,

I wanted to know if there is a way to customize the Event Triggers. Or are there some codes that can do that, rather than using the Event triggers?

For example in my case, I want to trigger an event when the Item number in the Parts List in my drawing changes. The goal is that if I change the Item number either via the Bill Of Materials or Manually it triggers the code.

For now I am triggering the rule Before saving.

Thank you for any help.

with a simple add-in you have the "parameterchange event" which is easier to use.

for ilogic

Sub Main()
 Dim oModelEvent As ModelingEvents 
 oModelEvent = ThisApplication.ModelingEvents 
 
 AddHandler oModelEvent.OnParameterChange, AddressOf oModelEvent_ParameterChange
End Sub

 Sub oModelEvent_ParameterChange(DocumentObject As _Document, Parameter As Parameter, BeforeOrAfter As EventTimingEnum, Context As NameValueMap, ByRef HandlingCode As HandlingCodeEnum)
 
 If BeforeOrAfter = kBefore Then
 MessageBox.Show("Before changing parameter : " & Parameter.Value)
 ElseIf BeforeOrAfter = kAfter Then
 MessageBox.Show("After changing parameter : " & Parameter.Value)
 End If 
 
 End Sub

Hi @sultan_mustun.  We can not change which events are available to use within the iLogic Event Triggers dialog.  We can unofficially add or remove rules under events on the 'This Document' tab by code, but we can not interact with the settings on any of the other tabs.  However, as @bradeneuropeArthur mentioned above, we can create custom event handler codes that will start 'listening' for specific events, then when those events happen, it will do something as a response.  But there are a limited set of events that we can listen for that way.  There are definitely more events to listen to using custom code than there are available in the Event Triggers dialog.  And if you listen to events using custom code, you can be much, much more specific about the details related to the events, so that you only respond to the event when certain other conditions are met, and can react in different ways depending on those details of the event.  However, there is no Event specifically for when you change the Item Number of an row in the assembly BOM, or for when you change that within a drawing's PartsList.  So, if it is possible to monitor for those actions, you would have to monitor a far more vague event, such as ApplicationEvents.OnDocumentChange Event.  But that event gets triggered a TON of times, for many different reasons, so any custom code you might use to monitor that event would need to be super efficient to keep from really slowing Inventor down.

Edit:  Attempting to monitor the DocumentEvents.OnChange Event (which is very similar in functionality) might be less intrusive / expensive to use, and will limit the monitoring to one specific document, instead of all documents.  Every Document type object has a DocumentEvents property which will return that DocumentEvents object.  Then when that document is truly and fully closed, that should get rid of the event monitoring that is running in the background that was started from the custom code.

Thank you Both,

I'm using the code provided by @bradeneuropeArthur but on Document Change Event as suggested by @WCrihfield .
