Dropdown in ALV Grid (OO)

Hi All,
I am populating a dropdown in the ALV grid, Now I have a requirement to fill this dropdown when I press enter button after selecting a value in the grid for a previous column ,I have written the code for this but the values are not getting filled into the dropdown , I tried debug the program and found out that the internal table I am using to fill the dropdown is getting filled with correct values but when I am calling the function
CALL METHOD g_grid->set_drop_down_table
    EXPORTING
      it_drop_down_alias = lt_dropdown.
the values are not getting passed to that field in the grid.
Please help.
I am posting the code also.
DATA : lt_ct1_mat TYPE STANDARD TABLE OF eina .
DATA: ls_dropdown TYPE lvc_s_dral.
DATA : wa like line of lt_ct1_mat.
SELECT * FROM eina INTO TABLE lt_ct1_mat
           WHERE matnr = l_partno.
IF NOT lt_ct1_mat[] IS INITIAL.
clear lt_dropdown[].
    LOOP AT lt_ct1_mat into wa.
      ls_dropdown-handle = '1'.
      ls_dropdown-value = wa-lifnr.
      APPEND ls_dropdown TO lt_dropdown.
      CLEAR ls_dropdown.
    ENDLOOP.
ENDIF.
CALL METHOD g_grid->set_drop_down_table
    EXPORTING
      it_drop_down_alias = lt_dropdown.
Thanks

ALV Grid - more than six values in a dropdown-field?

Hi,
I have realised an alv grid with several fields that contain a dropdown-field as valuehelp.
Although the dropdown-table has e.g. 20 entries there are shown only six entries on the alv grid. The user has to scroll through the values to choose another one. Is it possible to increase the number of shown entries of a dropdown-field on an alv grid?
Thanks for help.
Regards,
Sven Keller

Hi
you can specify the output length of a column in the fieldcatalog by specifying this filed in your fieldcatalog slis_fieldcat-outputlen .
And also one parameter i.e. slis_layout_alv-colwidth_optimize ,if you put this parameter as 'X' then it will optimize the column width depending on the content of your column.
You need to set the OUTPUTLEN field in the feildcat, the field catalog is then passed to the ALV function call, or method call.

Function code for dropdown on OO ALV Grid to trigger user_command

Hi Experts,
I know we can add a dropdown to a column of an OO ALV Grid, set values to the dropdown list and allow the user to select some these values.
However , what I'm not sure is that if we can *assign a function code to the dropdown * which would then trigger the event user_command ( PAI ) of the ALV class so I can handle the changes to when a particular value is selected from a dropdown list, just like we do in normal dialogs.
Now I know that I can register the 'Enter' event and handle the data changes in data_changed event, but that is something I want to avoid the user from doing as far as possible to make the report more user friendly.
Awaiting your valuable inputs and would really appreciate your help.
Thanks & regards,
Advait

Hi Advait,
No problem. Yes, this functionality requires changing the focus to other cell.
I think there is other solution. As the dropdown is kind of F4 activity try this way:
data: it_f4 type lvc_t_f4,
        wa_f4 type lvc_s_f4.
        wa_f4-FIELDNAME = 'CONNID'.
        wa_f4-REGISTER = 'X'.
        wa_f4-GETBEFORE = 'X'.
        wa_f4-CHNGEAFTER = 'X'.
        append wa_f4 to it_f4.
"register F4 event
CALL METHOD g_alv_grid_ref->register_f4_for_fields

      it_f4 = it_f4.

            i_row_id    = ls_mod_cells-row_id
            i_value     = space.
      ENDIF.
    ENDLOOP.

This approach works fine for picking value from input help. Never tried it for dropdown list. You have to try it out.

DropDown List in ALV Grid

Hii,
I am showing one of my Column Cells of ALV grid as DropDown List.
I have developed this Code for that.
DATA : ls_drpdwn TYPE lvc_s_drop,
 lwa_holders LIKE LINE OF gt_holders,
 gt_drpdwn1 TYPE lvc_t_drop.
FIELD-SYMBOLS : <lwa_fcat> TYPE lvc_s_fcat.
LOOP AT lt_fcat ASSIGNING <lwa_fcat>.
IF <lwa_fcat>-fieldname EQ 'SHNAME'.
 <lwa_fcat>-edit = 'X'.
 <lwa_fcat>-drdn_hndl = 1.
ENDIF.
ENDLOOP.
LOOP AT gt_holders INTO lwa_holders.
 ls_drpdwn-handle = 1.
 ls_drpdwn-value = lwa_holders-shname.
 APPEND ls_drpdwn TO gt_drpdwn1.
 CALL METHOD ref_grid->set_drop_down_table
 EXPORTING
 it_drop_down = gt_drpdwn1.
My Issue is How can I make my column's SHNAME cells to show Different Share Name List for different Holder's Id i.e Cell's should display dynamic List for Different Primary Keys.
Thanks and Regards,

ALV Grid Dropdown Click Event

I have created an ALV grid with a dropdown as one of the columns. This all works fine, except that I want to be able to react to a change in the value of each line's dropdown.
Currently I am reacting to the DATA_CHANGED event of the ALV grid, but that is too late. This event is only triggered if you change the value of the dropdown and then hit enter, or click on another cell or row.
I want to be able to react to a change in the value immediately without having to lose focus of the dropdown.
Is this possible?
As an example, I have a table of records with one column as a dropdown called "Reason". A change in "reason" should change which fields in the row are editable. I'm sure I could just make sure to call the check_changed_data method before saving but I am hoping for a more user-friendly approach where as the new value is selected, the columns in the row can change to their required editable status.
Of course points will be awarded.

Hi David,
Instead of using delayed call back event here i hav used data_changed event and this exacty suits ur requirement.....
even here we have to register the edit events............

ALV GRID Problem with reading contents

Hi there! I'm quite new with ABAP and I have some problems with the syntax of it. Maybe I should first describe my aim and then I'll show you my code.
1. I read contents from two database tables, called 'zbc_dan_registry' and 'zbc_dan_category'.
'zbc_dan_registry' has 2 columns: name, value.
zbc_dan_category' has 1 column: category.
Now I want to have an ALV Grid, that displays the contents of 'zbc_dan_registry' and one additional column with dropdown fields, where the user can select a category for each row. This is, what my code already does.
Now I want to save the contents of the whole table in a new table 'zbc_dan_registrz' (you see: 'registrz', not 'registry'!) with 3 columns:
name, category, value.
My problem is, how can I read the contents of the ALV Grid, with the user selected category for each row, and save them in an internal table? I've tried to adapt the code of "BCALV_EDIT_04", but I don't get it running.
Some detailled help would be great, you know, I'm really working hard to understand ABAP, but it's really hard for me. Thanks for your support and help!!
Here's my code so far:

Hello Raj
Actually all the code is described in PBO module, so you need to invoke this module in PBO when defining the screen.
For example, access transaction SE51, start in Change mode and inser line
 MODULE PBO.
Then activate the object
Best regards

Break-point in ALV-GRID OO if standard-button &PRINT_BACK is pressed.

Hi,
is it possible to set a break-point in Button '&PRINT_BACK'?
I will use it to test if i can use:
    CALL METHOD I_ALV_GRID->GET_FRONTEND_PRINT
      IMPORTING
        ES_PRINT = GS_PRNT.
and
    CALL METHOD I_ALV_GRID->SET_FRONTEND_PRINT
      EXPORTING
        IS_PRINT = GS_PRNT.

Anything other than buttons on ALV Grid toolbar?

Does anyone know if anything other than buttons can be placed on a ALV Grid toolbar, eg. a piece of text or an input field? The filter button for data selection may be too cumbersome/slow for a call centre operator; I want to have a display field with a dropdown identifying a data field and an input field to accept a value on which to select.

may be you can do some thing like this..instead of having a input field on the toolbar. have an input field above the ALV grid(this is applicable only when you are using Object Oriented ALV).
| input field : ________________ |
|__________________________________|
| ALV GRID OUTPUT |
|__________________________________|
you can have a button along with input field also. enter the value in it, and press enter . in the enter handling fetch all the data. and display in the ALV grid.
in the screen fiest create input field, and button, then place the custom control. on the custom control you place the grid.

Comments restricted to 25 Characters in ALV grid.

While entering comments in ALV grid it was not allowing to enter more then 25 characters but the comments we select from the dropdown are of more then 25 charcters.
Please advise how i can enter more then 25 char for comments.
Thank you

Event for the List Box in ALV Grid Control

Hello,
I have the below urgent requirment.
I have an ALV Grid Control built using ABAP Objects. In the grid, I have few fields and one of these fields is a List Box. Depending on the values selected, I need to enable or disable some fields. So, is there any event for the List box in ALV Grid Control.
For ex: I have 2 Fields, Designation and Commission. The designation field is a List Box field having 'Software Engineer' and 'Manager' as values. When I select 'Software Engineer', the commission field should be disabled. When I select 'Manager', the comission field should be enabled.
Early reply is hightly appreciated.
