pop-up window through double_click event in OOPS ALV

[Former Member]

Dear gurus ,

      i am trying to create a pop-up window through double_click event in OOPS ALV but i am facing a problem that i created a local class and  i want to create object with CL_GUI_CUSTOM_CONTAINER  for that local class.

     is it possible ???

     when i tried i am getting an error

''No CONSTRUCTOR has been defined for "C1" defined.''

     please share your valuable knowledge to resolve this problem.

Thank you.

Venkatesh.

Are you creating an instance of the C1 class somewhere?

I think a CREATE OBJECT RC1  is missing before the SET HANDLER part

Edit:

that is besides the fact that you're using the RC1 for event handler and container?  That are supposed to be two separate instances of different classes!

Example:

METHOD constructor.

     CREATE OBJECT:

       r_event_handler.

*   Creating custom container instance

     CREATE OBJECT r_ccontainer

       EXPORTING

         container_name              = c_custom_control_name

       EXCEPTIONS

         cntl_error                  = 1

         cntl_system_error           = 2

         create_error                = 3

         lifetime_error              = 4

         lifetime_dynpro_dynpro_link = 5

         OTHERS                      = 6.

*   Creating ALV Grid instance

     CREATE OBJECT r_alvgrid

       EXPORTING

         i_parent          = r_ccontainer

       EXCEPTIONS

         error_cntl_create = 1

         error_cntl_init   = 2

         error_cntl_link   = 3

         error_dp_create   = 4

         OTHERS            = 5.

     prepare_field_catalog( ).

     exclude_tb_functions( ).

     CALL METHOD r_alvgrid->set_table_for_first_display

       EXPORTING

         is_layout                          = s_layout

         it_toolbar_excluding          = t_exclude[]

       CHANGING

         it_outtab                           = r_mb11->t_data[]

         it_fieldcatalog                    = t_fieldcat[]

       EXCEPTIONS

         invalid_parameter_combination = 1

         program_error                 = 2

         too_many_lines                = 3

         OTHERS                        = 4.

     r_alvgrid->register_edit_event( EXPORTING i_event_id = cl_gui_alv_grid=>mc_evt_modified ).

     SET HANDLER r_event_handler->handle_data_changed_finished FOR r_alvgrid.

ENDMETHOD.

You will need to post some code of the event handler class that you have used. Otherwise it will be practically impossible to help you. For example what has been defined as C1 in your code.

In general you can define a local event handler class and call anything you want. You can call a popup function module or even another alv list

Here is my code

CLASS C1 DEFINITION.
   PUBLIC SECTION.
   METHODS: DOUBLE_CLICK FOR EVENT DOUBLE_CLICK
                              OF CL_GUI_ALV_GRID
                              IMPORTING E_ROW
                                        E_COLUMN.
   ENDCLASS.

CLASS C1 IMPLEMENTATION.
   METHOD DOUBLE_CLICK .

     READ TABLE IT_VARI INTO WA_VARI INDEX E_ROW-INDEX .

     CALL SCREEN 3000 STARTING AT 10 5 ENDING AT 25 5.

   ENDMETHOD.


   ENDCLASS.


   DATA :     RC1 TYPE REF TO C1 ,
                  RG1 TYPE REF TO CL_GUI_ALV_GRID .
