Urgent: about the checkbox in OOP ALV report

Question

Hi Experts,
I had use OOP method to display my ALV report. In the report I have a checkbox for each line. I had set this check box use below statements:
    gt_fieldcat_record-tabname = 'GT_ISSUE_INT'.
    gt_fieldcat_record-fieldname = 'CHECKBOX'.
    gt_fieldcat_record-checkbox = 'X'.
    gt_fieldcat_record-edit = 'X'.
    APPEND gt_fieldcat_record.
When I press the save button, then I will save the lines to my Z-table which its GT_ISSUE_INT-CHECKBOX = 'X'.
Now I click the checkbox to select several lines in my ALV report and then press save, but it do not work. Then I check the internal table GT_ISSUE_INT in debugger, I found the GT_ISSUE_INT-CHECKBOX = ' '. Above statements is not correct for the checkbox?? Or I need additional statements to move 'X' to GT_ISSUE_INT-CHECKBOX?? Please help!!!Thanks.

Hi,
If u want to read check box status from list, need to call function module explicitly.
see the sample code:
case sy-ucomm.
when 'SAVE'.
Data ref1 type ref to cl_gui_alv_grid.
      CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
        IMPORTING
           E_GRID = ref1.
       call method ref1->check_changed_data.
loop at GT_ISSUE_INT to workarea.
____ continue writing ur code.
function module read the data from list . and save the changes that made on list.
when u debug, u can see the check box status as 'X' after exucut\ing this fm and method.
reward if helpful.
