Hi Prabhavathi,
Here is how you handle double click events in Textedit control.
1)Create a custom control in screen (say TEXT_CONTROL)
2)In main program,
a) Declarations:
data: obj type ref to cl_gui_custiom_control.
      text type ref to cl_gui_textedit.
b) Create the instance of custom container
c) Create the instance of textedit control.
3)Now to handle double click events , create a local class as follows.
class shail_event definition.
public section.
methods:
handle_doubleclick for event dblclick of cl_gui_textedit .
endclass.
class shail_event implementation.
method handle_doubleclick .
here do the coding for handling the double click.
endmethod.
endclass.
4) Create an instance of the handler class(ie.ZSHAIL_EVENT).Let it be named hand.
5) Define varibles for event.
DATA: i_events TYPE cntl_simple_events,
      wa_events TYPE cntl_simple_event.
SET HANDLER hand->handle_doubleclick for text.
wa_events-eventid = cl_gui_textedit=>event_double_click.
wa_events-appl_event = 'X'. "This is an application event
APPEND wa_events TO i_events.
6)
    CALL METHOD texte->set_registered_events
      EXPORTING
        events                    = i_events
      EXCEPTIONS
        cntl_error                = 1
        cntl_system_error         = 2
        illegal_event_combination = 3
        OTHERS                    = 4.
    IF sy-subrc <> 0.
     MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
                WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDIF.
These are the basic steps needed for handling events in Textedit control.You can go to SE24 and type CL_GUI_TEXTEDIT to find the associated events of the class.
If you want the program, kindly send your mail-id so that I can mail it to you.
