Una de las cosas a tener en mente cuando estamos trabajando con los Receptores de Eventos (Event Receivers) en Share Point es que en los mismos mediante el parámetro que se recibe en el evento podemos tener acceso a las propiedades antes (Before Properties) y después (After Propierties) de la acción y al elemento de la lista (List Item).
Estos 3 elementos tienen características muy particulares dependiendo del tipo de evento que maneja y del objecto en el que se ejecuta dicho evento.
If you before check in your item event receiver only for lookup field, your code will become working incorrectly, when items number in lookup list more than 19.
When we try to add new item in "Software" list in Item Adding event we can see: Where "18" is an Id of category.
Learn how to leverage Custom Actions to extend the Share Point User Interface.
This session will describe the basics of Custom Actions, a demonstration to build one or more and apply them to a site in Share Point, as well as provide resources for additional information There are currently 4 demonstrations planned throughout the session, and possibly an additional demonstration if I can fit it in.
As per my Boston presentation, I will post all slide-decks, code samples, and answers to questions on my blog here within a few days following the Baltimore event.
Looking forward to meeting up with some friends, and meeting some new ones at this event.
And this acronym data will be used in many places to accomplish many business requirements.
