Row Select in ALV

I have an alv that displays data from a few tables.
If I select a row from teh ALV, then the following screen should display some of the fields of the row along with additional information..
I understand that the ON_CLICK event should be used once the row is selected..However, I would appreciate it if someone gave me more info on the same..
Thanks!

Hi,
Tray this:
<i> DATA: lr_table TYPE REF TO cl_salv_wd_table_lead_select,
               lr_node TYPE REF TO if_wd_context_node,
               lv_field1 TYPE (field1 of your alv table ).
lr_table ?= r_param.
lr_node ?= wd_context->get_child_node( 'NODE_TABLE' ).
CALL METHOD lr_node->get_attribute
    EXPORTING
      index = lr_table->IF_SALV_WD_TABLE_LEAD_SELECT~INDEX
      name = 'FIELD1'
    IMPORTING
      value = lv_field1.
</i>
With this code, you will have the value of the field 1 of the selected row.

If you are using OO for alv then
call method grid1->get_selected_rows
    importing
      et_index_rows = i_sel_alvrows[].
call method cl_gui_cfw=>flush.
describe table i_sel_alvrows lines v_dbcnt.
if i_sel_alvrows[] is initial.
* Info message : Please select a row
    message i176.                        " Please select a row'.
endif.
if v_dbcnt gt 1.
* Info message : Multiple Row Selection not possible
    message i177.                        " Multiple Row Selection not

Row Selection in ALV Grid created using CL_GUI_ALV_GRID

Hi,
I have ALV grid using cl_gui_alv_grid. I want to capture the row selection and display the selected rows in 2nd ALV grid (using cl_gui_alv_grid).
Method CALL METHOD Grid->get_selected_rows giving right no. of selected records first time and process these records by POST button and hence shows these records in next alv grid. but when i came back to 1st ALV by pressing BACK button on 2nd ALV then if I again select records on the same 1st ALV grid the same Method CALL METHOD Grid->get_selected_rows fires again. but this times it wouldn't give the selected records. I mean first time this gives me correct no. of selected records but 2nd time wouldn't.
how do I capture the row selection.?
Kindly suggest me. helpful answer will be appreciated.
Thanx in Advance.

Hi,
Write this code, you have to free the container.
MODULE user_command_0101 INPUT.
CASE sy-ucomm.
    WHEN 'BACK'.
       c_container->free( ).
       c_container1->free( ). " this is the container of secondary list.
       clear: r_grid, r_grid1, c_container, c_container1.

How to capture row selection in ALV output List

Hi experts,
I am displaying some output using ALV function module. My requirement is i have to capture how much rows user has selected in the output list, based on this information i have to perform some actions.
Please help me
Regards,
Sachin

Hi Sachin,
For this first you have to define a variable in your internal table of type c with length 1 and then while building the layout of the ALV, you have to pass this variable name to the layout field BOX_FIELDNAME.
Now when you select a particular row, then the corresponding field in your internal table willl be marked with X. So, for further processing, you can just loop through the table where 'BOX = 'X' and proceed.
For Example:
*      Structure for output details
TYPES: BEGIN OF gs_output.
        INCLUDE STRUCTURE zas_water_qlty_rep.
TYPES: selected(1) TYPE c,
       END OF gs_output.
DATA: object_tab            TYPE STANDARD TABLE OF gs_output.
CONSTANTS: lc_selected(8)             TYPE c VALUE 'SELECTED'.
lw_layout-box_fieldname     =   lc_selected.    "Field for checkbox
* Local workarea
DATA: lw_layout TYPE slis_layout_alv.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
       EXPORTING
            i_buffer_active          = gc_x
            i_bypassing_buffer       = gc_x
            i_callback_program       = lv_repid
            i_callback_pf_status_set = g_form_set_pf_stat
            i_callback_user_command = lc_uform
            i_structure_name         = lv_zas_water_qlty_rep
            is_layout                = lw_layout
            it_fieldcat              = g_fieldcat_tab[]
            it_events                = g_events_tab[]
            it_event_exit            = g_event_exit_tab[]
       TABLES
            t_outtab                 = p_object_tab
       EXCEPTIONS
            program_error            = 1
            OTHERS                   = 2.

Hi
I have a requirement in FM ALV where I have a search box and the user can search for criteria. I then search my underlying data table and if the data is found I want to put the row focus on the particular row. How do I set row focus in FM ALV?

User searches for PERNR 778.
778 is found at SY-TABIX 440. I now want the ALV to focus on row 440.

Multiple Row Select in ALV

Hi All.
I am trying to set multiple selection on in ALV using the method SET_SELECTION_MODE of IF_WD_SELECT_OPTIONS. (if_salv_wd_table_settings)
But it is always resulting in a dump saying that :
Selection type Multi is not allowed in combination with the selection Single of the data node
Now how can we change the context of the ALV?
What am i doing wrong here?
Thanks.

Hi this works fine here:
data: lr_table_settings type ref to if_salv_wd_table_settings.
lr_table_settings->set_read_only( abap_false ).
lr_table_settings->set_enabled( abap_true ).
lr_table_settings->set_selection_mode( CL_WD_TABLE=>e_selection_mode-multi ).
The node i bound to the ALV has selection 0..n.
Cheers,
Sascha

Get Selections From ALV on Multiple Selection Mode

Hi,
How can i get values of selected rows from ALV that has selection '0..n' (multiple selection) ?
Can somebody help me pls?
Thanks.

Hi Nurullah,
Steps to make multiple rows selectable in ALV:
1) Create the selection property of the node that you are binding to the DATA node as o..n
2) Un-check the, "Initialization Lead Selection" checkbox for the node which you are using to bind to the DATA node
3) In the WDDOINIT method specify the ALV's selection mode as MULTI_NO_LEAD. It is important that you set the selection mode to MULTI_NO_LEAD or else in the end you would be capturing 1 row lesser than the total number of rows the user has selected. This is because 1 of the rows would have the LeadSelection property & our logic wouldnt be reading the data for that row. Check the example code fragment as shown below:
DATA lo_value TYPE REF TO cl_salv_wd_config_table.
lo_value = lo_interfacecontroller->get_model( ).
CALL METHOD lo_value->if_salv_wd_table_settings~set_selection_mode
    EXPORTING
      value = cl_wd_table=>e_selection_mode-MULTI_NO_LEAD.
Steps to get the multiple rows selected by the user
In order to get the multiple rows which were selected by the user you will just have to call the get_selected_elements method of if_wd_context_node. So as you can see its no different from how you would get the multiple rows selected by the user in a table ui element. First get the reference of the node which you have used to bind to the ALV & then call this method on it. Check the example code fragment below:
METHOD get_selected_rows .
DATA: temp TYPE string.
DATA: lr_node TYPE REF TO if_wd_context_node,
            wa_temp TYPE REF TO if_wd_context_element,
            ls_node1 TYPE wd_this->element_node_flighttab,
            lt_node1 TYPE wd_this->elements_node_flighttab.
lr_node = wd_context->get_child_node( name = 'NODE_FLIGHTTAB' ).
" This would now contain the references of all the selected rows
lt_temp = lr_node->get_selected_elements( ).
    LOOP AT lt_temp INTO wa_temp.
" Use the references to get the exact row data
      CALL METHOD wa_temp->get_static_attributes
        IMPORTING
          static_attributes = ls_node1.
      APPEND ls_node1 TO lt_node1.
      CLEAR ls_node1.
    ENDLOOP.
ENDMETHOD.
Hope this helps resolve your problem.

How to process Line Selection on ALV Table in ABAP WebDynpro

Hi there,
I have a view with an ALV table whose context node retrieves its data from a Service Call for a method.
The method provides certain data of a database table which the ALV displays.
Now I would like to be able to select one row of that ALV table and after pressing a button or doubleclicking on the row or whatever a different view (as for me it is also ok on the same view) should appear to display the details of that selection.
I only need to know how to retrieve the selected data.
Or its index within the internal table.
I am already looking for hours for a useful thread and actually there is one which obviously is about a similar issue apart from the multiple selection part:
How to process multiple row selection in ALV table in Wendynpro ABAP? Help!
but i am afraid that i don't understand it. Or at least I misunderstand it since it does not work with me.
The system example mentioned in the thread does not help me either because it somehow does not correspond to my needs, does it?
It would be GREAT if somebody could help me with that. Please keep it simple for I am not an expert in webdynpro yet (obviously ^^) and also please explain in detail what I have to do with the context nodes since I am not sure whether the selection is stored in my already existing node or whether I need a special one for that.
Thanks!!
christina

Hi Christina,
If you just want to get one column data of the line that user clicked, use the Web Dynpro Code Wizard to Read Context of attibute you needed, then you will get code as follow:
* Define data for read attribute
    node_alv TYPE REF TO if_wd_context_node,
    elem_alv TYPE REF TO if_wd_context_element,
    stru_alv TYPE if_view_display=>element_alv ,
    item_column_name LIKE stru_alv-column_name.
* navigate from <CONTEXT> to <ALV> via lead selection
node_alv = wd_context->get_child_node( name = if_view_display=>wdctx_alv ).
* get element via lead selection
elem_alv = node_alv->get_element( ).
* get single attribute
elem_alv->get_attribute(
    EXPORTING
      name = `COLUMN_NAME'
    IMPORTING
      value = item_column_name ).
The value of column_name is stored in item_column_name.
If you need the index that the user clicked, try this:
* Definition of field symbol for index
FIELD-SYMBOLS : <fs_index> TYPE data.
* Get the selected index
ASSIGN r_param->index->* TO <fs_index>.
The index of clicked line is stored in field symbol <fs_index>.
Hope it will help.
Best Regards,
Stephanie
