Hi Nagarajan,

I dont want to print the Details , but only need display.

Hi Kishore,

To do that first you need to split the container

in to two containers and using dynamic doc class

you can display the data, handling Top-of-page event

in CL_GUI_ALV_GRID.

See my previous post Vijay gave the link also for

sample code.

Thanks&Regards,

Siri.

Hi Kishore,

See the below sample code and let me know if you have

any questions.

To display top-of-page in ALV grid using class.
I have done in my program like below, it is working 
for me check this.

1)First we nee to create one loacl class to implemment 
event receiver handler methods.

2) In PBO do below : First you need to split the container to two containers one is to palce top-of-page and other to display grid.

  IF dg_custom_container IS INITIAL.
* Create fieldcatalog for structure dt_final
    PERFORM fieldcat_init  USING dg_fieldcatalog[].
    dt_final[] = dt_members[].
* Create a custom container control for our ALV Control
    CREATE OBJECT dg_custom_container
        EXPORTING
            container_name = dg_mycontainer
        EXCEPTIONS
            cntl_error = 1
            cntl_system_error = 2
            create_error = 3
            lifetime_error = 4
            lifetime_dynpro_dynpro_link = 5.
    IF sy-subrc <> 0.
      dg_repid = sy-repid.
* Add your handling, for example
      CALL FUNCTION 'POPUP_TO_INFORM'
           EXPORTING
                titel = dg_repid
                txt2  = sy-subrc
                txt1  = 'The control could not be created'.
    ENDIF.
 
* Create TOP-Document
    CREATE OBJECT dg_dyndoc_id
                     EXPORTING style = 'ALV_GRID'.
* Create Splitter for custom_container
    CREATE OBJECT dg_splitter
               EXPORTING parent  = dg_custom_container
                         rows    = 2
                         columns = 1.
* Split the custom_container to two containers and move the reference
* to receiving containers g_parent_html and g_parent_grid
 
    CALL METHOD dg_splitter->get_container EXPORTING
                                   row                 = 1
                                   column              = 1
                               RECEIVING container = dg_parent_html.
    CALL METHOD dg_splitter->get_container EXPORTING
                                  row                 = 2
                                  column              = 1
                              RECEIVING container = dg_parent_grid.
 
 
* Set height for g_parent_html
    CALL METHOD dg_splitter->set_row_height
      EXPORTING
        id     = 1
        height = 25.
* Create an instance of alv control
    CREATE OBJECT dg_grid1
          EXPORTING i_appl_events = c_x
                    i_parent = dg_parent_grid.
* Registering events
    CREATE OBJECT dg_event_receiver.
    SET HANDLER dg_event_receiver->top_of_page FOR dg_grid1.
    SET HANDLER dg_event_receiver->handle_top_of_page FOR dg_grid1.
    SET HANDLER dg_event_receiver->handle_end_of_list FOR dg_grid1.
 
* Grid display
    CALL METHOD dg_grid1->set_table_for_first_display
             EXPORTING
               i_structure_name = 'TP_FINAL'
               is_layout        = ds_layout
             CHANGING
                it_fieldcatalog  = dg_fieldcatalog[]
                it_outtab        = dt_final.
 
* Initializing document
    CALL METHOD dg_dyndoc_id->initialize_document.
 
* Processing events
    CALL METHOD dg_grid1->list_processing_events
                      EXPORTING i_event_name = 'TOP_OF_PAGE'
                                i_dyndoc_id  = dg_dyndoc_id.
 
 
  ENDIF.
* Setting focus for created grid control
  CALL METHOD cl_gui_control=>set_focus EXPORTING control = dg_grid1.
 

Hope this will help you.

Thanks & Regards,

Siri.

Hi,

Thanks for your posting for handling top of page event in OO ALV.

Could you please give me the logic which you have used for the PERFORM add_text USING dl_text 'S' or 'H'?

And can you explain the logic why we are mentioning 'S' or 'H' with that perform statement?

Thanks in advance if you reply ASAP.

Regards,

JK
