ALV grid Enter event

Hi
I have a grid view where I can insert a new line and enter values in 2 of its columns. I wish to update other columns based on the values that the user enters in the 2 columns.
I have tried both of the following but neither gives me exactly what I want :-
i_event_id = cl_gui_alv_grid=>mc_evt_modified. " and
i_event_id = cl_gui_alv_grid=>mc_evt_enter.
I want the user to be able to TAB (or mouse) between the 2 columns. After entering a value and TABing away from the column then the other columns in the row should be updated. When the user is finished experimenting with values, he hits ENTER then the 2 columns should cease to be editable (I know how to enable/disable edit on cells).
If I use mc_evt_modified then TABing between the 2 columns updates the other columns nicely. However I cannot distinguish between TAB and ENTER and so cannot switch of EDIT when the user hits ENTER.
If I use mc_evt_enter then the other columns are not updated when I TAB away. This is of course correct, but not what I want. When the user hits ENTER then everything is updated and I could switch of Edit at this point.
It looks like I need a different event to DATA_CHANGED and DATA_CHANGED_FINISH. This event should be invoked when the user hits ENTER even if nothing has changed in the Grid. I have tested DOUBLE_CLICK but it does not work.
So what I really want is for the user to see the results of his changes imeadiately (using the TAB) and then to finish the insert by hitting ENTER. Remember that since the user TABed away to see the updated columns, a subsequent ENTER will not result in a DATA_CHANGED event since the Grid is unchanged.
Perhaps I am designing a bad GUI. When does one normaly switch off EDIT on cells in a newly inserted line.

can't you add a button instead of enter to switch off EDIT ?

How can I call functionality of ALV Grid by event of button outside grid?

Hello,
How can I call functionality of ALV Grid by event of button located outside ALV Grid? For example how to fire printing of this ALV Grid by button click elsewhere on the screen (not in toolbar of ALV Grid).
Best regards,
Josef Motl

hi Motl,
these are steps to create a button in ALV and trigger an event from it..
1.Use the parameter i_callback_pf_status_set in the function module REUSE_ALV_GRID_DISPLAY
i_callback_program = gd_repid
i_callback_pf_status_set = 'SET_PF_STATUS'
form set_pf_status using rt_extab type slis_t_extab.
set pf-status 'NEWALVSTATUS'.
endform.
You have to copy the standard ALV pf stauts to 'NEWALVSTATUS' and add your button.
2.You have to do the following to process the new button click.
i_callback_user_command = 'USER_COMMAND'
form user_command using i_ucomm like sy-ucomm
is_selfield type slis_selfield.
case i_ucomm.
3. to copy the standard pf status to a new one.go to the ALV screen and take the menu System -> Status. Then look for the standard pf status. Copy this to Z range and then add your new button.

Issue with ALV Grid and events

Hi,
I am creating an ALV Grid with fields Matnr,Charg,Labst,Meins. The first three fields are editable and the last (MEINS) is read only.
Now I am trying to fill the MEINS field programmaticly after entering the MATNR and confirm with enter/return.
I think that I have to "overload" the enter event of the alv grid to fill the MEINS everytime when a MATNR was entered. But I don't know how I could implementing this. Could you give me a hint how I could solve this problem?
(The behavior should look like in transaction MIGO)
Thanks

Hi Alex
When you press enter an event is triggerd and function code is filled in sy-ucoom or you can say in ok_code. At that time PAI event occurs. In PAI of that screen you need to check ok_code and load new data in table which you passed to ALV and also refresh the ALV.
data: ok_code like sy-ucomm.
PAI----screen 100
case ok_code.
when 'ENTER'.
select data
and refresh ALV
then again call
funtion to display ALV

ALV Grid-- "DOUBLECLICK EVENT" doesnt work with "DATA_CHANGED_FINISHED" ??

Hello at all,
i have an ALV-Grid with 2 different Events.
.....First Event: "Doubleclick"
Second Event: "data_changed_finished"
If i click to a column than it should be trigger the Doubleclick Event.
And if i write some text in the column and "Press" Enter than it should be trigger the Event data_changed_finished.
But the Problem is:
If i click double to any column it will allways trigger the Event datachanged_finished_
But if i replace the Event data_changed_finished with Event data_change, than it will be work.
What can I do to resolve the Problem??
Please give me some ideas, what i can do!!!
With kind regards

Know alv grid on event click

Hi,
Is it possible to know the alv grid (TYPE REF TO cl_gui_alv_grid) on the event click? In fact, on a screen, I have 2 alv grids and I would like to store the alv grid name for a process at click moment.
Thanks.
Edited by: Xavier Couloumies on Sep 12, 2008 2:07 PM

you might declare two differents methods for the two grids
PUBLIC SECTION.
METHODS:
    HANDLE_DOUBLE_CLICK
      FOR EVENT DOUBLE_CLICK OF CL_GUI_ALV_GRID
        IMPORTING E_ROW
                  E_COLUMN,
    HANDLE_DOUBLE_CLICK2
      FOR EVENT DOUBLE_CLICK OF CL_GUI_ALV_GRID
        IMPORTING E_ROW
                  E_COLUMN.
something like that
then , in the implementations do something like this
METHOD HANDLE_DOUBLE_CLICK.
     PERFORM X USING GRID = '1'.
ENDMETHOD.
METHOD HANDLE_DOUBLE_CLICK2.
     PERFORM X USING GRID = '2'.
ENDMETHOD.
and do the respective validations on that form
hope this help

Hi,

Check_changed_data method on editable ALV Grid ( class cl_gui_alv_grid)

Hi guys,
I use the following method (register_edit_event) in the PBO soon after first display of an editable ALV grid to register enter as an event to do validations on fields like qty. If user enters some character like 'abc' for qty and hits enter on keyboard, ALV grid pop's up a standard message ( I haven't coded for this.Since I use DDIC structure in field catalog, the Std. ALV program takes care of it. ). THis takes care of the validation before I click on save.
call method alv_grid->register_edit_event
                        exporting
                           i_event_id = cl_gui_alv_grid=>mc_evt_enter.
This works fine. But I want this validation to run when I also click the SAVE button of the screen. Is it possible to run this standard validation in my PAI event eg. SAVE ? I thought I will be, by calling the method check_changed_data in my PAI event. But this is doing nothing. Does this method conflict with register_edit_event or something ? So , basically what I am looking for is to trigger the event or call the method which does the same work as the "check" button on ALV grid.
Any advice or tips or sample code is greatly appreciated.
Thanks,
Shareen

Hi Shareen,
Handle the data_changed event in the grid.
Whenever you make changes in the data in ALV Grid this event would be triggered. Here you can perform additional validations that you may need to perform.
    METHODS handle_data_changed
      FOR EVENT data_changed OF cl_gui_alv_grid
      IMPORTING er_data_changed.
Implementation:
METHOD handle_data_changed.
    PERFORM validations USING er_data_changed.
ENDMETHOD.
FORM validations USING er_data_changed TYPE REF TO cl_alv_changed_data_protocol.
DATA: ls_good TYPE lvc_s_modi.
DATA wa LIKE LINE OF lt_good_cells.
CALL METHOD g_grid->register_edit_event
    EXPORTING
      i_event_id = cl_gui_alv_grid=>mc_evt_modified.
LOOP AT er_data_changed->mt_good_cells INTO ls_good.
    CASE ls_good-fieldname.
    WHEN 'FIELDNAME'. "Your fieldname
        CALL METHOD er_data_changed->get_cell_value "Get the changed value
          EXPORTING
            i_row_id    = ls_good-row_id
            i_fieldname = ls_good-fieldname
          IMPORTING
            e_value     = temp. "Your temp variable
        "Make your validations here.
    ENDCASE.

ALV Grid - Add/Delete/Change Values

Hi,
I have an ALV Grid with editable fields. I know want to process the changed, deleted and added lines.
Is it not possible to get the shown ALV table back?
In the event DATA CHANGED I have only attributes and methods of CL_ALV_CHANGED_DATA_PROTOCOL. So I have a method to get deleted, changed and added rows. But this event is only thrown, when I press enter or something else, but not when I´m pressing the icon for "add" or "delete".
End when the event is thrown, i´m only getting the changed data. In some case it´s not possible to react in the right way.
For example:
I have an internal table with 5 lines. I now build the alv grid with that table. When I´m now adding a line with the "add" Icon, the event is not thrown. But if I press enter, I can handle the event. In the event methods I now have one line in added data. But when I´m deleting and adding again, it sometimes "forget" some actions I have done. Isn´t there a better way to compare the changed data in ALV with my "real" internal table?
Next example:
If I´m adding a new line to the alv, I can compare the key of that line with the exisiting keys of my internal table. If the user has typed in a line with the same key, I can throw and error message.
But when the user is changing a line it should be possible to update that line. But how to compare, if the line is a new addewd line or a changed line?
I hope it´s not too complicated to understand!
Reward points guaranteed!

As we can now make our ALV Grid editable we may require controlling input data. The ALV Grid has events data_changed and data_changed_finished. The former method is triggered just after the change at an editable field is perceived. Here you can make checks for the input. And the second event is triggered after the change is committed.
You can select the way how the control perceives data changes by using the method register_edit_event. You have two choices:
1. After return key is pressed: To select this way, to the parameter i_event_id pass cl_gui_alv_grid=>mc_evt_enter.
2. After the field is modified and the cursor is moved to another field: For this, pass cl_gui_alv_grid=>mc_evt_modifies to the same parameter.
To make events controlling data changes be triggered, you must select either way by calling this method. Otherwise, these events will not be triggered.
To control field data changes, ALV Grid uses an instance of the class CL_ALV_CHANGED_DATA_PROTOCOL and passes this via the event data_changed. Using methods of this class, you can get and modify cell values and produce error messages. Here are some of those methods:
get_cell_value: Gets the cell value. You pass the address of the cell to the interface.
modify_cell : Modifies the cell value addressed via parameters.
add_protocol_entry : Add a log entry. You make use of standard message interface with message type, message id, etc
protocol_is_visible : Make the error table visible or not.
refresh_protocol : Refreshing log entries.
Table 16 Methods to use for controlling data changes
With the reference of the instance, you can reach information about modifications. These useful attribute tables are:
MT_MOD_CELLS
Contains addresses of modified cells with row_ids and fieldnames.
MP_MOD_ROWS
Contains modified rows. Its type is generic.
MT_GOOD_CELLS
Contains cells having proper values
MT_DELETED_ROWS
Contains rows deleted from the list
MT_INSERTED_ROWS
Contains rows inserted to the list

Displaying items in a single line in ALV grid using ALV_TOP_OF_PAGE.

Hello Guys,
I am having a problem in displaying items in a single line in the ALV Grid using event ALV_TOP_OF_PAGE.
My requirement is to group items on a single line i.e. in the example below, Vendor code and posting date are on the same line. The next line the prints Vendor Name and Document no.
Vendor Code: 123123                               Posting Date : 01.01.2011
Vendor Name: ABCD                                 Document No: 152246598.
Here is my code in subroutine 'ALV_TOP_OF_PAGE',
wa_list_comments-typ = 'S'.
wa_list_comments-key = ''.
wa_list_comments-info = 'Vendor Code'.
APPEND wa_list_comments TO it_list_comments.
wa_list_comments-typ = 'S'.
wa_list_comments-key = ''.
wa_list_comments-info = 'Posting Date'.
APPEND wa_list_comments TO it_list_comments.
The above code prints in the following format i.e one below the other,
Vendor Code: 123123
Posting Date : 01.01.2011.
I also tried using HTML_TOP_OF_PAGE, but it didn't work.
Can anybody please help me out with this.
Regards,
Danish.

Hi Danish,
Your problem is with the alignment and you need some fix positions .
The solution i feel is u can use as below :
In CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
use

Now on calling routine call use cl_dd_document class :

Enter Key Event in Editable ALV Grid

Hi all,
I am trying to create and editable ALV grid using the REUSE ALV FM.
On the grid after changing a value, if I press enter key the pai is not triggered. I have tried the various example programs (BCALV*) but could not find anything relevant.
Basically I need similar functionality to normal module pool programming as in validations on screen done when enter key is pressed after screen entry.
Is it possible to capture the Enter keypress on the ALV grid?

Hello Preet
I can only tell you how I would solve this using the ALV grid control (CL_GUI_ALV_GRID) because I have abandoned using ALV function modules.
The problem with running through PAI is whether the focus (i.e. the cursor) is still on the control or already on the (surrounding) main program. If the control has the focus, you do not run through PAI.
I would add a "Refresh" button to the toolbar of the ALV list. Normally, this button is already there or you only have to make it visible.
When the user pushes this button you catch the corresponding user-command and call the CHECK_DATA_CHANGED method to see if values have been changed on the editable grid. If so, the previous method will fire event DATA_CHANGED.
Now, in the event handler method (e.g. HANDLE_DATA_CHANGED) you receive as input a data change object (CL_ALV_CHANGED_DATA_PROTOCOL). This object contains all changed values. These values you will need to make your checks.
I assume that the logic will be similar using ALV function modules.

Uwe

How to capture the event in ALV grid display?

Hi experts,
How to capture the event in an ALV grid display which is editable. I have to capture the TAB key or ENTER key.
regards,
Arul Jothi.

Hi Arul,
Take a look at sample program BCALV_EDIT_03. (Find string "register ENTER" in the program to see how to register)
Basically you have to Register edit events using method call REGISTER_EDIT_EVENT and then write a handler method for event DATA_CHANGED..
If you are using a REUSE..GRID fm then first get the grid reference using function module GET_GLOBALS_FROM_SLVC_FULLSCR and then repeat the above procedure..
Hope this helps..

Handling events in ALV grid

hi,
Hi,
I am displaying some fields from VBAP in ALV gid and have give drop down check box to storage location making it editable so if the user changes Storage location of
some entries and clicks SAVE button, when we click save button i need to capture all the rows that were been changed and update VA02 using these records through bapi.
but iam not able to capture this SAVE event but iam able to capture Enter and cursor event.
i have written following code for this

Hi Sirisha,
          You can get the event code for Enter because you have regitered in the event reciever .
But for the SAVE you will have to set in the PF-status of the screen and not the ALV-grid save .
Please award if helpful.
