Last night I was working on a project that had some many to many database relationships. On one side of the relationship, someone decided to use zero as the default “nothing selected” sort of key. This simply doesn’t work with Entity Framework, or probably most other .NET ORMs.
While I was working through my post regarding generically formatting Angular data within a component, another generic implementation that I needed arose. I needed a way to, in a very generic fashion, raise events from a child component to its parent. Within the context of an Angular table, this could typically coincide with a click event that needs to take action, or apply some logic, to the child’s bound data. Event Emitters in Angular readily facilitate this type of functionality.
