Hi ,

DropDownByKey provides static data in DropDown and DropDownByIndex makes it dynamic.

<b>DropDownByKey</b> : Is used when we want to use data dictionary type.For this create a dictionary of simple type in the dictionary.

Creating the Simple Type:

project>dictionaries>Data Types-->Simple Types right click and select Create Simple Type.

After entering the name and package, open and click on "enumeration" tab . Add the Value and Description to be listed in dropdown.The created simple type can be used for DropDownByKey.

Binding it to the UI element:

Create a valueattribute and change the type to the dictionary type created simple type . Finally bind the DropDownByKey UI element to the value attribute.

<b>DropDownByIndex:</b> Is used when we get the data from the back end database. Here we directly bind the DropDownByIndex UI element to the context model node attribute.

Hi Pradeep,

Have a look to this Tutorial:

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/internat...

In General If you want to add a Dropdown then you can simple make a dictionary object. Go to <b>Dictionaries-> Local Dictionary-> Data Types-> Simple Types -></b> [<i>Create Simple type</i>].

Now name this simple type (say: <i>dropdownkey</i>), go to the enumeration tab, add the <b>Value</b> and <b>Descriptions</b>.

In the UI elements create a <b>DropDownByKey</b>, In the context of the view add a attribute and map the datatype of this object with the newly created dictionory object (<i>dropdownkey</i>).

In the view designer go to the <b>Properties Tab</b> of the DropDownByKey UI element. There map the "<b>selectedKey</b>" property with the attribute created in the context.

Just deploy it and try to check this, you will get a drop down in the UI.

I hope this helps you.

Regards,

Pravesh
