Method to transfer data from Table control to Internal table

Question

hi,
Hi,
I´m working with CL_GUI_ALV_GRID and use the following methods:
- CALL METHOD grid->set_table_for_first_display, to display my ALV;
- CALL METHOD grid->get_selected_rows, to select the rows.
But i have some fields that can suffer alterarions in the values...
How can i recoup this values from the screen? Is there any method to do this?
thnks.

HI,
You neeed to handle the change event.
Example below...
Definition.
Code:
CLASS lcl_event_handler DEFINITION.
  PUBLIC SECTION.
    METHODS:
          handle_data_changed
        FOR EVENT data_changed
        OF cl_gui_alv_grid
        IMPORTING er_data_changed.
ENDCLASS.                    "lcl_event_handler DEFINITION
Implement
Code:
    CLASS lcl_event_handler IMPLEMENTATION.
  METHOD  handle_data_changed.
    CONSTANTS:
      lc_wa(11) TYPE c VALUE '<LW_SDITM>-'.
    DATA:
      l_subrc TYPE sy-subrc,
      l_variable TYPE string,
      lw_good TYPE lvc_s_modi.
    FIELD-SYMBOLS:
      <lw_sditm> TYPE /powercor/sditm,
      <lw> TYPE ANY. "Generic field symbol
    LOOP AT er_data_changed->mt_good_cells INTO lw_good.
    Update the internal table
      READ TABLE t_item_sel ASSIGNING <lw_sditm> INDEX lw_good-row_id.
      IF sy-subrc EQ 0.
        CONCATENATE lc_wa lw_good-fieldname INTO l_variable.
        ASSIGN (l_variable) TO <lw>.
        IF sy-subrc EQ 0.
          <lw> = lw_good-value.
        ENDIF.
     ENDIF.
     ENDLOOP.
  ENDMETHOD.                    "handle_data_changed
ENDCLASS.                    "lcl_event_handler IMPLEMENTATION
Set for your grid.
Code:
  SET HANDLER g_handler->handle_data_changed FOR my_grid.
