Row change event in WDP ALV

[Former Member]

Dear Experts,

Can anyone help me how to raise event on row change event in WDP ALV.

I have two columns namely ' From date and two date' in my ALV table.

Hi,

In your ALV, Make the From date as input field and create one  on_cell_action for that field mean while inside that action get the entered from date and add six month to that data then set that to To_Date field.

John.

Hello John,

Thanks for your prompt reponse.I have done the code changes according to you.But "ON_CELL_ACTION" event is getting triggered only if i select "From date" from F4 help on clicking on "Enter" key.

Hello Aravindan,

Interface if_wd_view_controller does not have method register_on_enter_for_f4.

Thanks

Hi Katrice ,

Hi Katrice,

you can use ON_CELL_ACTION_EVENT to achieve ur requirement by following below steps.

1.Enable Cell Action Event, in the method where you are defining ALV settings as below:

           if_salv_wd_table_settings~set_cell_action_event_enabled ( abap_true ).

2. Define a new z_event handler method with  (ON_CELL_ACTION ) event at the view where you are displaying ALV.

3. In t he method you will get an imorting parameter r_param, Where u can get column name, values, index of a particular cell .

for your case you will get the From Date value when u change the default date in that particular cell as below.

r_param->column  =  ' From Date  Field Name '

  move  r_param->*value to fs_newdate.

   move r_param->index = lv_index.

call method get_static attributes_table, so that you will get the alv table,

Now read the table, with index = lv_index.

change TO_DATE = FS_NEWDATE + 6 MONTHS (Use ur logic watever )

modify the alv_internal_table with TO_DATE.

Bind the table again with the node to display the modified TO_DATE.

Hope, You can also on data check also with help of below link

Hi Katrice,

Component SALV_WD_TABLE has several events, two of which may be useful to you, ON_DATA_CHECK or ON_CELL_ACTION. You can see an example of implementing an ALV event in the following document. The document shows how to implement a different ALV event but you'll get the general idea.

Hi Katrice,

Try ON_DATA_CHECK. If that too doesn't fire when you want, you may want to create an event handler method for each of the ALV events and set breakpoints in them just to see when they fire and find out if any of the ALV events can be used for what you want.

Also, if you want to capture the date value right after F4 help, the view's hook method wddomodifyview may work for you if no ALV event does since it gets executed upon return from F4 help.
