Regarding validating data in editable ALV in OOPS

I'm using the data_changed event in my ALV grid to validate the user's
entry in the ALV grid. My code finds the errors when the user originaly
enters the wrong data, highlights the errors in the grid, and popups u the
list of error messages.
My problem occurs when the user only fixes some of the errors and leavs
some data errors still in the grid. The data_changed will check the lnes
the user has fixed. However if they neglect to fix one of the errors,the
code doesn't reread the entry since the data didn't change from the
original entry. The error still exist and I don't want to allow the uer
to continue until they have fixed all of the errors. Is there another
event or coding that I can use to ensure the user fixes all of the errrs.
I know I could loop through the ALV grid table outside of my methods, ut
that would require rewriting all the checking again which seems very
inefficient.
Thanks,
Phani.

How to Transfer Data from editable ALV grid control to internal table?

Hi,
Can anyone give me a simple example by which I can transfer data from editable alv grid control back to the internal table. The ALV has been created by OO approach.
I would appreciate if the solution is provided without handling any events.
Regards,
Auro

Hello Auro
You simply need to call method go_grid->check_changed_data at PAI of the dynpro displaying the ALV grid. If data have been changed on the editable ALV grid then this method will raise event DATA_CHANGED. If you do not want or need to handle this event (e.g. for validating the edited values) then you do not define any event handler method.

Regarding editable ALV in OOPS

Hi,
I have an editable alv.
I have requirement like i need to validate the data which is edited on pressing "ENTER" or "SAVE"
for this iam using the event DATA_CHANGED
and define a local class lcl_event handler and also set handler for it.
But iam able to validate using this event only if the data is changed inspite of SAVE or ENTER its getting triggered.
But if the data is not changed its not triggering please suggest me an event which triggers on clicking SAVE in menu bar.
Thanks,
Phani.

Hello
If the event is not triggered but you need to do the validation then just call the event handler method yourself:
" PAI: USER_COMMAND module
CASE gd_okcode.
   WHEN 'SAVE'.
     " Now call your event handler method directly
     go_grid->handle_data_changed( )
       EXPORTING
WHEN OTHERS.
ENDCASE.
Within your event handler method you can easily distinguish between whether the method is triggered by the control framework or by your direct call:
METHOD handle_data_changed.
" instance exists -> triggered by framework
IF ( er_data_changed IS BOUND ).
" direct call
ELSE.
ENDIF.
ENDMETHOD.

Save changed data in editable ALV

Hi experts,
I have a problem with an editable ALV. I get data out of a table and show it with my web dynpro application in an alv. Now I made the alv editablke, so that I can change the content of each cell in the alv in the web browser. But how will this changed data be saved? I want that it will be changed after ENTER or clicking a save button. I have a button, but all I tried yet brought no success.
Which code has to be in which method? Have I to do something eith the context. How can I reach that the changed content is also changed in the table, so that after reload the web dynpro application, the changed content is shown?
It would be nice if you had an answer with code examples and the exact place where to put it in, because I am very new to ABAP and WD4A.
Thanks a lot!
Best Regards
Ingmar

If you look on the following lokn, there is the tutorial "Editing ALV in Web Dynpr for ABAP".
There is described how to save the data. But in the implementation of On_data_check on page 8 and 9 the code detail for saving the data to database is missing, because the flight model shall not be changed.
Would the missing code be the solution? What is the code?
Thanks!!!

Save data in editable ALV

Hi all,
I am using an editable ALV in webdynpro using which I would like to save some data to a table. In the list of standard functions, I see only options like 'Insert row', 'Delete row' etc. There is no option to Save the edited data.
Even if I declare a user defined function, how do I specify the action it would trigger? Any help would be greatly appreciated. Thanks in advance.
Regards,
Nithya

Hi Nithya,
Once you edit an ALV, the data is automatically updated to the context node, you map in the DATA field of controller usage (of the component usage).
If you want to trigger event for change in ALV, see the below tutorial.
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/bd28494a-0801-0010-45a3-fc359d82d3e8">Using Events with ALV Tables
in Web Dynpro for ABAP</a>
If you want to trigger a event for user defined function,
Create a event handler method in the view. Specify event,
 ON_FUNCTION of the interface controller of ALV for the event handler method.
The importing parameter r_param of the method contains unique ID of the
 function for which the UI element is assigned.
For reference see the below tutorial. It will be useful.

Get data in editable ALV back to internal table without data_changed ev?

Hi,
I have an editable ALV using classes to whch I have users the option to edit directly on the screen or upload data from an excel. The event data_changed gets triggered when users edit the table on the screen.
However when EXCEL is uploaded, I refresh the table display. So, I need a way to get the data from the ALV into a internal table to check which rows were update using the excel and save them into the db table.

Hi!
For more information, inspect programs suiting the mask "BCALVEDIT*" and the thread with header "How to make a row of ALV editable " (I know this is some more steps further from your demand but it may be useful) at URL " How to make a row of ALV editable " .

Validation of data in editable ALV report output for particular field

Hi Experts,
I have one input enabled field in ALV output. How to validate the data once user enters in that field and press enter? Is it possible to capture the value, hit the enter after user enters the data?
Thanks,
Surya Prakash

Halo Prakash,
1 First you should registeer the ENTER Event.
call method g_grid->register_edit_event
               exporting
                  i_event_id = cl_gui_alv_grid=>mc_evt_enter.
2 Declare event handler method for Event data_changed of cl_gui_alv_grid.
handle_data_changed
         for event data_changed of cl_gui_alv_grid
             importing er_data_changed.
3 Inside the Event handler method , you get the event parameter er_data_changed type ref to CL_ALV_CHANGED_DATA_PROTOCOL.
loop at er_data_changed->mt_good_cells into ls_good.
      case ls_good-fieldname.
        when 'FIELD1'.
          call method check_FIELD1.
        when 'FIELD2 '.
          call method check_FIELD2
      endcase.
    endloop.
4 Inside the Method check_FIELD1 and check_FIELD2 you can do the validation check .
call method er_data_changed->get_cell_value( Passing the row no and field name).
if the check fails you can use add_protocol_entry to write the error.
5 Finally call
er_data_changed->display_protocol.

Enable User Defined toolbar button on click - editable alv grid using oops

Hi all,
I have created editable alv using oops concept.
created 2 user defined toolbar button save and print using method toolbar
ls_toolbar-text      = 'Print'.                         "#EC NOTEXT
    ls_toolbar-quickinfo = space.
    ls_toolbar-checked   = space.
    APPEND ls_toolbar TO e_object->mt_toolbar.
requirement is
initially print button should be disabled, and save enabled
when i click save button, print button should be enabled.
I want coding in editable alv oops concept
kindly help
regards
senthil kumar

Halo Senthil,
You should call set_toolbar_interactive method of cl_gui_alv_grid in the on_user_command( ie the event handler for event user command) .
method on_user_command.
case e_ucomm.
when 'SAVE'. or whatever your function code is .
my_save_flag = 'X'.
call method grid->set_toolbar_interactive.
endmethod.
This triggers the toolbar event of the
cl_gui_alv_grid. Inside the eventhandler method ( ie the on_toolbar method ) you should set the toolbar.
if my_save_flag = 'X'.
read table e_object->mt_toolbar
clear l_toolbar-disabled.
modify e_object->mt_toolbar.
endif.
e_ucomm will not have the function code if the save button is not in the toolbar area.
then you can set the my_save_flag in the data_changed event handler of the Cl_gui_alv_grid.

Arshad

Event Handling in Editable ALV

Hi all,
I am having 4 to 5 fields in my module pool screen and at the same time i am having a custom container wherein, there is editable ALV [using OOPS Editable ALV inside a custom container].
Here in editable ALV, i am having an editable field called dealer code.When i enter dealer code in editable ALV and press enter
my dealer name and dealer address in editable ALV inside Custom Container should get populated.
But when the cursor is inside the custom container in that editable field none of my screen eventsModule pool events
are getting triggered [Hence my values are not getting populated.When the cursor is outside the custom container all my module pool events are working fine, hence values are getting populated....
*I am handling the event in my program.But i don't know where exactly i should create object and handle this as
nothing is getting triggered[pai or pbo] when my cursor is inside the custom container.
Could you suggest me anything...*
Waiting for your repiles...

Hi
First of all you need to creat object in PBO.
You must be calling method SET_TABLE_FOR_FIRST_DISPLAY.After this call method REGISTER_EDIT_EVENT.And then REFRESH_TABLE_DISPLAY.
In OK code create an OK code with name "OK".This is for ENTER key.
And in that call method CHECK_CHANGED_DATA.
Sample code for REGISTER_EDIT_EVENT is given below:
*--event to detect if data gets edited
CALL METHOD OBJ_ALV2->REGISTER_EDIT_EVENT
 EXPORTING
 I_EVENT_ID = CL_GUI_ALV_GRID=>MC_EVT_MODIFIED
 EXCEPTIONS
 ERROR = 1
 OTHERS = 2.
IF SY-SUBRC <> 0.
 MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
 WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
Sample code for CHECK_CHANGED_DATA
*--when alv is edited and ENTER button is clicked then data
*will be saved in internal table and edited data will
*be displayed on alv
IF V_OK_CODE = 'OK'.
*--metohd to detect if data was changed in oops alv
 CALL METHOD OBJ_ALV2->CHECK_CHANGED_DATA
 IMPORTING
 E_VALID =
 CHANGING
 C_REFRESH = 'X'
ENDIF.
Hope this solves your problem.
Thanks

<<The code came from [here|https://wiki.sdn.sap.com/wiki/display/Snippets/ABAP-UploaddatafromExceltoSapusing+OO]>>
Thanks in advance.
am just a beginner in learning abap objects.pls help.

It wasn't your source code, was it?
Please take the time to read the rules of engagement. As it stands, your question is far too general. There are examples of editable alvs in many location on the net. You must search for them. Please note these are not training forums, they are expert forums. When you have a specific question, we'll be glad to assist.
