I have a need for Interception on the client (as opposed to the server) when saving. Not to do validation, but to update fields such as ModifiedOn and ModifiedBy.

I know this could be done on the server through the SaveInterceptor, but there really is no need for it to be done on the server as the data is available on the client and no need to make the server do the work.

As far as I can tell, the EntityManager.Saving event would be the best place to do this.

Hi Greg,

Your comment about the EntityManager.Saving event makes sense. Per our documentation:

"The (EntityManager.Saving) event handler can use the IdeaBlade.EntityModel.EntitySavingEventArgs.Entities list to validate, modify, delete or add entities as needed."

Where you'd be modifying the entity in this case.

If you want to relief the server of some workload, that would most certainly help. (although I wouldn't expect noticeable improvement results for this particular example)

Regards,
   Silvio.

Greg,
I believe you are using Cocktail. In Cocktail you can centrally intercept the save with an EntityManagerDelegate.

Hi Marcel,

Yes, you are correct. Will check that out. Thanks to you both and have a Great New Year!
