Hi All,
Can anyone help me to understand the use of the parameter I_HELP_REQUEST_HANDLER in class IF_WD_SELECT_OPTIONS->ADD_PARAMETER_FIELD
I am trying to find out if there any way to handle dropdown selection action in WD ABAP Select Option.
Thanks

Hi,
It's like an event handler .You have to create an action under ACTIONS tab and pass this action name to the to I_HELP_REQUEST_HANDLER of ADD_SELECTION_FIELD of IF_WD_SELECT_OPTIONS.

Hi Katrice,
Thanks for your reply.
I saw your earlier post where you mentioned this comments. But I_HELP_REQUEST_HANDLER is of type OBJECT. I can't pass my action name here as string in quote, like 'MY_ACTION'. can you please share any sample code which shows how to pass this action name while calling method ADD_PARAMETER_FIELD.
Thanks
Angshuman
Did you look at WD component DEMO_SELOPT_DROPDOWN?

Honestly, I am not sure how the help request handler parameter has been used by SAP. Also, I am not sure if it would be able to listen to the event.
What you could do is enhance component WDR_SELECT_OPTION and its assistance class.
At the moment, I am not sure if the component raises the event on drop down change
