09 Sep: A Guide to the New ALV Grid Control – Part 3

Adding new GUI elements to an ALV Grid instance is event-controlled and requires experience in ABAP Objects event handling. There is an event for each element type (toolbar push button, toolbar menu, and context menu). In the relevant event handler method, you define the properties of an element (such as its menu options) and assign a function code to each executable function.

The ALV Grid Control solves this problem. Its user interface provides a set of generic functions (e.g., sorting, filtering) for handling tabular data. It also confers the many benefits of controls technology to users, enabling more operations by mouse, and interaction with other controls, such as drag-and-drop. Developers simply plug the ALV Grid Control into their applications and the tool takes care of the rest. You do not need to do any further programming to offer users these functions. How you “plug” the control into an application is the first thing I will show you in this month’s blog. So lets get started!

Let’s review some of the technical aspects of controls technology:

-The SAP Control Framework

-The Automation Queue, and the issues surrounding “flushing” it

-Event handling

-Error handling

Including Controls Technology controls on the front-end establishes a client/server relationship between the application server and the controls on the presentation server.
