Method to transfer data from Table control to Internal table

[Former Member]

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.

You neeed to handle the change event.

Implement

Code:

CLASS lcl_event_handler IMPLEMENTATION.

METHOD handle_data_changed.

CONSTANTS:

lc_wa(11) TYPE c VALUE '<LW_SDITM>-'.

DATA:

<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>.
