• Key Concepts: 
  An event source is an object in the Web Dynpro framework that triggers an event when a certain action is performed. It can be a UI element, such as a button or a checkbox, or it can be an external source, such as a timer or a database. The event source is responsible for sending the event to the Web Dynpro application. 
  
  How to use it: 
  In order to use an event source in Web Dynpro, you must first create the event source in the layout editor. Once the event source has been created, you can then bind it to an action in the controller. This action will be triggered when the event source is activated. 
  
  Tips & Tricks: 
  When creating an event source, make sure to give it a meaningful name so that it is easy to identify later on. Additionally, make sure that the action that is bound to the event source is properly configured so that it will be triggered when the event source is activated.
