HI,

I have used the sample program for my understanding.In the below program there is a code

mycontainer type scrfname value 'BCALVC_EVENT1_CONT1'

in the above code what is 'BCALVC_EVENT1_CONT1'.Is this a program???can anyone help me in this.

Thanx in advance..

program bcalvc_print.

*&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&

Purpose:
~~~~~~~~
This program illustrates how the events for print processing
- PRINT_TOP_OF_PAGE
- PRINT_END_OF_PAGE
- PRINT_TOP_OF_LIST
- PRINT_END_OF_LIST

are handled. The corresponding handler methods control the
appearance of the list printed.

*----

To check program behavior
~~~~~~~~~~~~~~~~~~~~~~~~~
Print the list shown (It has got only three pages).
Remark: If you choose "Druckansicht" (preview?!) before printing,
the output for event PRINT_END_OF_PAGE is left out due
to scrolling.
Create a spool entry and preview your printout by calling
TA sp01 to reduce paper output please.

*----

Essential steps (Search for '§')
~~~~~~~~~~~~~~~
1. Define a (local) class for event handling
2. Define a method for each print event you need.
3. Implement your event handler methods. Use WRITE to provide output.
4. Link used print events and event handler methods.
5. In case of PRINT_END_OF_PAGE, you must set 'reservelns' to
the number of reserved lines at the end of a page.

*&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&

*********

Predefine a local class for event handling to allow the
declaration of a reference variable.

class lcl_event_receiver definition deferred.

*********

data: ok_code like sy-ucomm,

g_max type i value 100,

gt_sflight type table of sflight,

g_repid like sy-repid,

gs_print type lvc_s_prnt,

gs_layout type lvc_s_layo,

mycontainer type scrfname value 'BCALVC_EVENT1_CONT1',

reference to custom container: neccessary to bind ALV Control

custom_container type ref to cl_gui_custom_container,

grid1 type ref to cl_gui_alv_grid,

event_receiver type ref to lcl_event_receiver.

§ Step 1. Define a (local) class for event handling

- PRINT_END_OF_LIST (list footer)

Definition:
~~~~~~~~~~~

class lcl_event_receiver definition.

public section.

§ 2. Define a method for each print event you need.

methods:

handle_top_of_page

for event print_top_of_page of cl_gui_alv_grid,

handle_end_of_page

for event print_end_of_page of cl_gui_alv_grid,

handle_top_of_list

for event print_top_of_list of cl_gui_alv_grid,

handle_end_of_list

for event print_end_of_list of cl_gui_alv_grid.

Hi,

'BCALVC_EVENT1_CONT1' is the name of the custom control created for that particular alv.
