OnInitialization
This event handler is processed directly after OnRequest during page processing.
This handler implements data retrieval. The data is stored in page attributes and is therefore accessible in the layout and in the other event handlers.
While the event handler OnCreate is used to initialize objects needed for entire page, OnInitialization is used for getting data from database tables.
If you develop a BSP for managing a shopping basket, the shopping basket object is initialized using OnCreate and then filled with selected products. Here, this would be the catalog ID and the number of objects. You use OnInitialization to read the short texts from the database, calculate the current subtotal, and so on.
You can access the following objects in the implementation toolbar:
