How to set visible row count dynamically ?

[former_member190818]

Hi,

I've a requirement to set visible row count dynamically in FPM. Initially there will be only one visible row in the list. Once Insert Row button is clicked I need to show the visible row as 2. I'm not able to find the place where can I set visible row count. The rows are getting appended but not the row count expanding to 2.

Please help.

Thanks,

JMB

Hi,

i raise an event 'Z_SET_ROW_COUNT' with the config_key and the number as parameter
i've created an app_controller in webdynpro and have this added to the configuration settings.
in the method AFTER_PROCESS_BEFORE_OUTPUT of this app controller

CASE io_event->mv_event_id.

     WHEN Z_SET_ROW_COUNT.

       set_visible_row_count(

                       io_event_data = io_event->mo_event_data

                       it_uibbs      = it_uibbs ).

In this new method

METHOD set_visible_row_count .

it works for me.
