How to make use of class cl_gui_alv_grid

[Former Member]

Hi Expert,

I have an ALV which has been developed using Object Oriented Programming. Now i need to enable the push button, that will enable the users to select any row they want. i have investigated and found the i need to update the field SEL_MODE with the value 'A' in order to have this functionality working.

i have tried with my obect to call the method set_table_for_first_display, but i'm getting an errror message saying that it is protected or unknown..

Can anyone let me know on how to enable this functionality?

Thank you very much.

Hi ,

To enable Push button,

Handle this event BUTTON_CLICK of Cl_gui_alv_grid .

or u can use GET_SELECTED_ROWS method of CL_GUI_ALV_GRID for getting selected rows .

from that method u will get selected row indexes & Row ID's .

Hi,

refresh your objects when you use set_table_for_first_display.

  IF gr_custom_container IS NOT INITIAL.
    CALL METHOD gr_custom_container->free.
    CLEAR gr_custom_container.
  ENDIF.

  CREATE OBJECT gr_custom_container
         EXPORTING container_name = gv_container.

  CREATE OBJECT gr_grid
         EXPORTING i_parent = gr_custom_container.

  CALL METHOD gr_grid->set_table_for_first_display
    EXPORTING
      is_layout       = gs_layout
    CHANGING
      it_outtab       = gt_zalcrdata
      it_fieldcatalog = gt_catalog.

To get the selected rows you can use:

  CALL METHOD gr_grid->get_selected_rows
    IMPORTING
      et_row_no = gt_roid.

* Data variables used
DATA: gr_custom_container TYPE REF TO         cl_gui_custom_container,
      gr_grid             TYPE REF TO         cl_gui_alv_grid,
      gt_catalog    TYPE          lvc_t_fcat,
      gt_roid       TYPE          lvc_t_roid,
gs_layout     TYPE          lvc_s_layo.

Best regards,

John
