Hi Antonio ,

As said in my previous post you class definition and implementation is not complete , in the calss definition you need to define a method for the event DOUBLE_CLICK of the class CL_GUI_ALV_GRID , this even has three parameters E_ROW , E_COLUMN , ES_ROW_NO , so you will get the row and the column on which the user had clicked.

Here is a sample of how you class definition must look

**--> Class for event handeling

class event_handler definition.
  public section.
    methods : handle_double_click
                for event double_click
                of cl_gui_alv_grid
                importing e_row 
                             e_column.
endclass.

Please do refer to the standard program for more info.

Hi Antonio ,

Your class implementation does not seem to be complete , you need to first get the record on which the user clicked .

Please refer to the standard programs provided .They start with BCALV_GRID*.

Hi ,

No change in the feild catalog is required , but as anil has mentioned in his post do remember to register a handler , other wise the method will not be called.

hi antonio,

You have to change ur fieldcatalog , while using containers u have to use FM LVC_FIELDCATALOG_MERGE

data : pt_fieldcat type table of lvc_t_fcat.

call function 'LVC_FIELDCATALOG_MERGE'
       exporting
            i_structure_name = 'SFLIGHT'
       changing
            ct_fieldcat      = pt_fieldcat.

" add the below 2 lines at the top of ur code 

*for event handling
CLASS LCL_EVENT_RECEIVER DEFINITION DEFERRED.
DATA : W_EVENT_RECEIVER    TYPE REF TO LCL_EVENT_RECEIVER.

"also add this after calling SET_TABLE_FOR_FIRST_DISPLAY

*cretes an instance of event receiver class
  CREATE OBJECT W_EVENT_RECEIVER.

*sets double click event
  SET HANDLER W_EVENT_RECEIVER->HANDLE_DOUBLE_CLICK FOR W_GRID.

Hi Antonio,

You haven't set the handler for the grid.

You can code that directly after you set the data for first display.

event_receiver type ref to <class>.

create object event_receiver.

set handler event_receiver->handle_double_click for grid3.
