Hi,

when u give value during coding for dropdown than u use dropdownbyIndex..

n if u use simple data type..n creating values using enumeration..then u'll hav to use dropdown bykey....

for Image UI element check this:[https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b0e10426-77ca-2910-7eb5-d7d8982cb83f]

Hi

The drop down by key is value container of key value pairs here key is a string and value may be any object.To populate we can use a simple type with ennumeration of values.

Binding with selected Key

Drop down by index is the one which stores key value pairs where key is an index.Here we need th bind with Texts property. The Attr and Node you must create and populate the node with elements.

Dropdown by key you can populate either by using simple type or also dynamically you can populate.

Image UI ele source you need to bind with the Image file name directly and place it in mimes
