How to add a event to a dynamic created input field in web dynpro?

[Former Member]

Hi,

i created "dynamic" a ui element, now i would add e event, i dont know how, but i had searched on diffrent places, but i get no info.

I only read something about add_eventhandler and to registrated a evendhandler. I couldnt believe that this is the correct way.

Here the code for a selection_field...:

  lt_range_table = wd_this->go_so->CREATE_RANGE_TABLE( i_typename = '/BVCCSAP/VE_BCOD1' ).
  wd_this->go_so->add_selection_field(

      i_id = 'BCODE'
       it_result = lt_range_table
       i_description = 'Barcode'
       i_no_intervals = abap_true
      i_read_only = read_only

).

Thanks a lot for your help and hints

Hi Katrice,

thanks for the 2 links, the first link works and the second i get a 404 page error..

Do i missunderstand this, i checked the first link and i never saw a line where i can assign a eventhandler.

If i do this with the layout designer, i add the input field, then i have some options and one options is onEnter. But i not saw this, sorry..

I saw that i have to create the input field like this

CALL METHOD cl_wd_input_field=>new_input_field and to set_enter a event, but i havent found a example, do you now a good one....to understand this...

thanks a lot

Therer are two ways you can assign an action to the "OnEnter"-event of your input field:

1. in method cl_wd_input_field=>new_input_field you have the parameter:

ON_ENTER

You just have to assign your action name to this field and it will be called on the OnEnter-event of your InputField.

e.g:

     lr_input_field = cl_wd_input_field=>new_input_field(

                                             id = 'INP_MY_INPUT_FIELD'

                                             on_enter = 'MYACTION'

                                             ).

2. You can use the method SET_ON_ENTER.

like:

     lr_input_field->set_on_enter( 'MYACTION' ).

Just make sure, you have created and implemented this action and its handler.
