Select All

Hi Experts,

I have a functionality select all , it is not activating when clicking on select all.

I write the code in do_prepare_output.

   me->typed_context->btqract->set_selection_mode( EXPORTING iv_selection_mode = cl_bsp_wd_context_node_tv=>selmode_multiedit ).

     lr_sel_col ?= me->typed_context->btqract->collection_wrapper->get_marked( ).

     IF lr_sel_col ISBOUND.

       IF  lr_sel_col->size( ) < 1.

         lv_enable = abap_false.

       ELSE.

         lv_enable = abap_true.

       ENDIF.

   ENDIF.

Please help me get the solution.

Thanks & Regards,

Prasaditha.
