Grid ALV - Interactive

Question

Hi All,
I have a ztable and need to create a ALV(Grid) report with the functionality of Editable, Insert a new row to ALV, Delete (on clicking the delete button the specific row has to enable in the database table as flagged for deletion) on executing the report, I will be having 2 button in pf-status(Insert, Delete).  All changes has to replicate in the ztable.
Im new to such kind of interactive ALV.  Can anyone guide me.
Thanks n advance,
Vichu

hi, 
to handle change data u have to do something like this.
        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.
CLASS LCL_EVENT_HANDLER IMPLEMENTATION .
  METHOD HANDLE_DATA_CHANGED.
    PERFORM HANDLE_DATA_CHANGED USING ER_DATA_CHANGED.
  ENDMETHOD.                    "HANDLE_DATA_CHANGED
ENDCLASS.
______________________-form______________________________
FORM HANDLE_DATA_CHANGED  USING    ER_DATA_CHANGED
           TYPE REF TO CL_ALV_CHANGED_DATA_PROTOCOL.
  DATA : LWA_MOD_CELL TYPE LVC_S_MODI.
  LOOP AT ER_DATA_CHANGED->MT_GOOD_CELLS INTO LWA_MOD_CELL.
    WA_MOD-ROW  = LWA_MOD_CELL-ROW_ID.
    APPEND WA_MOD TO IT_MOD.
  ENDLOOP.
ENDFORM.
    i would suggest to insert new row use this code.
    clear wa_ouptut.
    append wa_ouptut to it_output.      " append a blank row.
   call method c_alv-> refresh_table_display.
to delete a particular row from grid do it like this .
from the form u will get the row index user selected for deleting into itab  it_mod.
    LOOP AT IT_MOD INTO WA_MOD.
      READ TABLE IT_OUTPUT INTO WA_OUTPUT INDEX WA_MOD-ROW.
      if sy-subrc = 0.
         DELETE IT_OUTPUT INDEX WA_MOD-ROW.
      if sy-subrc = 0.
          DELETE ZDATA FROM  WA_ouptut.
   endif.
endif.
try it out if any issue reply back.
Thanks,
Gaurav
