Hi,

Please read the pages 61 to 64 in the following e-book,

https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b06c8c9a-19a4-2b10-d985-9ae7a438...

This will give you a detailed description of DDBK , DDBI and all the other UI elements that can be used in Web Dynpro for Java.

hi,

DDBK

A DropDownByKey UI element provides the user with a selection list from which he or she can select no more than one entry. The UI element consists of a text field, a button, and a selection list. Any list entry already selected is displayed in the text field. When you select the pushbutton, a list with all possible values is displayed.

The dropdown list box UI elements do not differ from each other when displayed on the screen. However, the data binding model for the DropDownByKey UI element has a completely different concept

DDBI

A DropDownByIndex UI element provides the user with a dropdown list box. You cannot select more than one entry from the selection list. The UI element consists of a text field, a button, and a selection list. Any list entry already selected is displayed in the text field. When selecting the button, a list with all possible values is displayed.

Hope this information helps you.

regards,

Kris
