Problem with Event data_changed and multiple ALVs

Former Member — Wed, 14 Aug 2013 08:28:01 GMT

Dear Developers,

i am facing a problem with the event data_changed on a screen that uses multiple editable ALVs.

The user is able to switch through the editable fields of each ALV and enter values. If he presses the TAB-Key my event-handler is processed and the cursor jumps to the next field.

The problem is: If the user entered something into the last editable field of the actual ALV and presses TAB, the ALV loses focus without raising data_changed event.

I know, that i can force the data_changed by calling method check_changed_data of CL_GUI_ALV_GRID, but as no event is triggered by losing focus, i cant do that. Regular PAI is too late to react on the data entered. And pressing enter in a screen where you want to enter many data right away is not acceptable.

Is there any other way to react on filling the last editable field?

I use CL_GUI_ALV_GRID for ALVs and edit-event CL_GUI_ALV_GRID=>MC_EVT_MODIFIED.

Thanks in advance!

In another application an ALV placed on a popup-dynpro shows the same behaviour. If you push the tab-key focus is set to a button of the gui-status without raising event data_changed.

Hi Sandeep,

thanks for your answer, but the problem is, that my event handler is not executed, if i edit the last editable cell of the ALV and then press the tab-key. If i press Enter it is processed. If i click on a field of this particular ALV it is processed. But if i leave the ALV by pressing TAB after editing/changing the last editable field, the Event data_changed is not raised by the ALV.

Hi,

Use the below code

USE this EVENT

METHODS: HANDLE_DATA_CHANGED

FOR EVENT DATA_CHANGED_FINISHED OF CL_GUI_ALV_GRID

IMPORTING E_MODIFIED

ET_GOOD_CELLS.

if O_GRID2 is initial.

pass V_STABLE parameters as 'X'

CALL METHOD O_GRID2->REGISTER_EDIT_EVENT

EXPORTING

I_EVENT_ID = CL_GUI_ALV_GRID=>MC_EVT_MODIFIED

EXCEPTIONS

ERROR = 1

OTHERS = 2.

CALL METHOD O_GRID2->SET_READY_FOR_INPUT

EXPORTING

I_READY_FOR_INPUT = 1.

CALL METHOD O_GRID2->SET_TABLE_FOR_FIRST_DISPLAY

EXPORTING

I_SAVE = 'X'

I_DEFAULT = 'X'

IS_LAYOUT = WA_LAYOUT

CHANGING

IT_OUTTAB = IT_MATNR

IT_FIELDCATALOG = IT_FCAT

EXCEPTIONS

INVALID_PARAMETER_COMBINATION = 1

PROGRAM_ERROR = 2

TOO_MANY_LINES = 3

OTHERS = 4.

ELSE.

CALL METHOD CL_GUI_CONTROL=>SET_FOCUS

EXPORTING

CONTROL = O_GRID2.

CALL METHOD O_GRID2->REFRESH_TABLE_DISPLAY

EXPORTING

IS_STABLE = V_STABLE

EXCEPTIONS

FINISHED = 1

OTHERS = 2.

endif.

There is an EVENT of alv DATA_CHANGED_FINISH try putting the logic of the last cell in this also.

Hi Mohammed Yakub,

thanks for your answer. I tried (data_changed_finish) again. It is not raised, if the ALV loses focus. Besides the Signature is useless for my usecase. i do check the given Data on data_changed. data_changed_finished is supposed to be used to change/update displayed data, according to some sap-note i read the other day...

Hi Bharath,

this Event is neither raised by cl_gui_alv_grid if you tab out of the grid...

Thanks anyways!

Does nobody have a solution? Is there a SAP-Note? I can not imagine, that this behaviour would be normal. Do you need code examples? It can not be right, that data_changed is not raised, after editing the last field and not pressing enter. It makes the whol mc_event_modified Kind of useless - in my opinion..

Please help!
