Event Handler for WebDynpro Search Help

[Former Member]

Hi,

is it possible to register an event handler on a WebDynpro Search Help (Standard Search Help, no OVS or Application defined) for event opened or closed?

I need to know whether the user is typing into the InputField manually or uses the SearchHelp. It would be also nice if I can react to the SearchHelp if the result table is empty (no search results).

I'm using wd_this->wd_get_api( )->register_on_enter_for_f4( register_on_enter = abap_true ) but this is also fired if the user is pressing ENTER on it owns so I don't knwo where the input comes from.

There is the class CL_WDR_VALUE_HELP_HANDLER which has two events that can fit for me (IF_WD_VALUE_HELP_FORWARD~VALUE_HELP_CALLED and IF_WD_VALUE_HELP_FORWARD~VALUE_HELP_CLOSED) but I don't know how to listen to this events from my View.

Hi,

Yes, It's possible to create listener for value_help_closed event. Check this blog by chris: http://scn.sap.com/blogs/chris.paine2/2010/07/13/asug-ui-influence-council-youre-wrong-well-sort-of-...

Hope this helps u.,

Hi,

thank you, this helps me a lot!

Is it possible to  react to the SearchHelp if the result table is empty (no search results)? I would like to show an popup "No entries found for XY. Would you like to create?" and close the SearchHelp.

Hi,

This scenario can be done easily using OVS. Please deactivate DDIC search help and use OVS to achieve this.

Hi,

this was my first idea but I'm not sure if I show a confirm popup within an OVS (Phase 2) and the user clicks on Yes or No, is it possible to close the SearchHelp window?
