Understanding Dynamic Actions

Dynamic actions provide a way to define complex client-side behavior declaratively without the need for JavaScript. Using the Dynamic Action Create wizard, you can specify an action that is performed when a defined set of conditions occur. You can also specify which elements are affected by the action, and when and how they are affected.

When working with dynamic actions, you should be mindful of the fact that the more dynamic actions you add to a page, the greater your overall page size will be. This is because the dynamic action framework emits additional code to the client for each dynamic action defined, which then also needs to be downloaded and executed by the framework in the client. Please see "Debugging Dynamic Actions" for information on how to debug problems.

The process of implementing a dynamic action involves the following:

Edit or create an item on a page. This item is referenced within the dynamic action in defining when it fires.
Create a dynamic action from the application page that invokes the action.
Run your application to test the dynamic action.
