Event Handler
| Event Handler | Description |
| OnCreate | OnCreate is called once when the page is first created (stateful mode), and performs a once-off data initialization or object creation. |
| OnRequest | OnRequest is called whenever a request is made for a particular page and is used to restore the internal data structures from the request. This is important when working in stateless mode. |
| OnInitialization | This event handler is mainly used for data retrieval. For example, it allows data required for displaying the BSP to be read from the database. It can also execute any program. |
| OnInputProcessing | This event handler checks and processes user input. It can also define navigation, that is, whether the user should be taken to the same page or another when the BSP is called. |
| OnManipulation | You can use this event handler to manipulate the HTTP data stream later. |
| OnDestroy | This event handler is available for special functions. |
About Application Class
举个例子, 这里的AC, 就是在APPLICATION 定义的一个CLASS, 可以说是一个功能性的CLASS 可以在整个APPLICATION 中任意的使用, 包括其METHOD, ATTRIBUTE， 有点类似WebDynpro的Assistance Class的感觉。

Important Notices:
The BusinessGraphics UI element has been extended to include a new bindable property called imageData within Netweaver 7.02/7.20 version, so you do not need the some steps below. This new attribute imageData allows you to receive an XSTRING with the image data that is rendered by the IGS. This avoids the extra steps that you detail for getting direct access to the rendered IGS chart and makes it simple to integrate the IGS content into downloads and/or Adobe Forms.
