Event associated to dropdown with select options

[Former Member]

Hello,

   I have the following code in the method WDDOINIT:

* add a new field to the selection

  wd_this->m_handler->add_selection_field(

       i_id                  = 'TIPO'

       i_description     = 'Tipo'

       it_result            = range_table

       i_as_dropdown  = abap_true

       it_value_set      = lt_value_set

  ).

I need to retrieve the event associated with the dropdown to perform different actions depending on the selected value.

An easy way to solve it would use the dropdown tool layout but this involves an additional task.

Does anyone know how to do? It's possible to do what I indicate?

Thanks in advance!!!

Hi,

Create an Action ( in Actions tab) and pass that action name to parameter I_HELP_REQUEST_HANDLER of method add_selection_field( )

Hope this helps u,

Hello Kiran,

   How I have to pass the name to parameter? Since this parameter is of type object.

Thanks.

Hi,

You can pass the action as object reference as below

     data lr_action type ref to if_wd_action.

     lr_action = wd_this->wd_get_api( )->get_action( name = 'ON_SELECT' ).

     now pass lr_action to the method ADD_SELECTION_FIELD

Hope this helps you.

Hello Rama,

   I create the action and pass the parameter as you indicated me, but still not working. I've put a break point in the action and does not stop.

  data lr_action type ref to if_wd_action.

  lr_action = wd_this->wd_get_api( )->get_action( name = 'SELECCION_TIPO' ).

* add a new field to the selection

  wd_this->m_handler->add_selection_field(

  i_id              = 'TIPO'

  i_description     = 'Tipo'

  i_help_request_handler = lr_action

  it_result         = range_table

  i_as_dropdown     = abap_true

  it_value_set      = lt_value_set

  ).

What more can I do?

Thanks!!!

Xavi.

Hi Xavi,

Sorry, this event will trigger for when we press F4 ( for search help call ) on select option.

I don't think we have a standard method to register to an event on select options.

But we can use global options CHECK button for validating the data.

Hope this helps you.

Hi,

Yep. It's for F4 help handler and I expected that it will trigger for value set as well( too bad that there is no provision ).

As suggested, you have press Enter/ Check to handle the drop down on select.
