problem with gt_grid

Former Member — Thu, 08 Feb 2007 23:33:54 GMT

Hello,

I am debugging through sap system code and i reached the following:

in form Marks_save there is an abap statement

call method gt_grid-grid->get_selected_rows

but they did not define gt_grid anywhere.

In the abap function that I am writing, I wrote the following:

data gt_grid type grid occurs 0 with header line.

data lt_rows type lvc_t_row.

call method gt_grid-grid->get_selected_rows

importing et_index_rows = lt_rowd.

But when I am compiling, the compiler is telling me gt_grid is not a structure and it does not have a component grid.

So what seems to be the problem?

Basically what i want to do is to get the selected rows from a grid, any ideas on how to do this?

Hi,

The get_selected_rows method is in the cl_gui_alv_grid object.

Refer to this sample code:

DATA: w_grid TYPE REF TO cl_gui_alv_grid.

DATA ls_trows TYPE lvc_t_row.

DATA ls_row TYPE lvc_s_row.

DATA:lw_valid TYPE char1.

CALL METHOD w_grid->check_changed_data

IMPORTING

e_valid = lw_valid.

IF sy-subrc EQ 0.

"ignore

ENDIF.

CALL METHOD w_grid->refresh_table_display.

IF sy-subrc EQ 0.

"ignore

ENDIF.

CALL METHOD w_grid->get_selected_rows

IMPORTING

et_index_rows = ls_trows.

IF sy-subrc EQ 0.

"ignore

ENDIF.

Award points if helpful.

Regards,
