You can find examples of this interface element in the system in the Web Dynpro application WDR_TEST_UI_ELEMENTS, and in the component WDR_TEST_EVENTS in the view DropDownByKey. Note that when you program value lists dynamically in context (NODE_INFO->SET_ATTROBUTE_VALUE_SET() ), that you have to insert a CONDENSE if you use integer types for an attribute.ĬL_WD_DROPDOWN_BY_KEY=>E_TEXT_DIRECTION-INHERITĬL_WD_DROPDOWN_BY_KEY=>E_TEXT_DIRECTION-LTRĬL_WD_DROPDOWN_BY_KEY=>E_TEXT_DIRECTION-RTL The associated UI elements are:įor dynamic programming, the same properties, events and aggregations are available as in View Designer. Other properties that can be inherited are defined in the associated higher-level class. You can find more information about using dropdown listboxes with index data binding in AbstractDropDownByKey. See Data Binding within Web Dynpro generally, and Data Binding of UI Element Properties, and Data Binding of a Dropdown Listbox. However, the data binding model for the DropDownByKey UI element has a completely different concept. The dropdown list box UI elements, DropDownByKey and DropDownByIndex, do not differ from each other when displayed on the screen. If no label has been set, and no descriptive text has been specified for the appropriate bound context element in the ABAP Dictionary, the property tooltip is checked. To enable the development of accessible applications the property label is checked during the syntax check. This is also usually more efficient than DropDownByIndex. When the user clicks on a particular dropdown button, their respective dropdown list will open up to you. We will now create a form with multiple dropdown menu of various online technical subject tutorials lists like C, C++, PHP, MySQL, and Java, categorised into several categories. If you want to create a table with dropdown lists, whereby each table row has the same values in its dropdown list, you should use DropDownByKey. In the above examples, we have created a single dropdown list.
When you select the pushbutton, a list with all possible values is displayed.
Any list entry already selected is displayed in the text field. The UI element consists of a text field, a button, and a selection list. You cannot select more than one entry from the selection list. A DropDownByIndex UI element provides the user with a dropdown list box.
