Navigation through windows

[Former Member]

Hi to all,

i have a problem, this is my senario: I have a main window (1) in which there is a view with a data table. and a button. When i click this button a new window (2)is opened and where there is an input field and another button "save".

When i fill the field and i click on button ,i'd like to close this window2 and refresh the data table of the window1. I suppose that i have to link an outboud of the window1 to the inbound of the window2, so the views on the window2 can refresh, because the code of SELECT data from the table is in the method init of the View.

How can i do this? Someone can help me?

Thanks

HI,

If these windows are of same component then try to use the component controller for these data exchanges....

Try to code in component controller and it's attributes...

How are you opening this window ..is it a popup or external window....

Lekha.

Yes the window2 is a pop up. So you are saying that when i click in the save button, i lhave to ink this action to a component controller method which modify the context of the table, It correct? But in this case the page, and so the table in the window1, are automatically refreshed?

Thanks for your answer

hi ,

proceed like this :

1 create context nodes in ur component controller and make contributes under it

2 map the context node node in both of ur views view1 and view2 , to ur component controller

JUST DRAG AND DROP the context node from ur component controller to ur views

ie map the context

4 since u r mapping the context which is binded to ur input field with component controller , tht wud be accessible in

ur view1 of window win1, similarly map the node which is binded with ur table UI to the node in component controller

5 in ur view2 ( popup ) , subscrible to action on click of button

DATA lo_window_manager TYPE REF TO if_wd_window_manager.
  DATA lo_api_component  TYPE REF TO if_wd_component.
  DATA lo_window         TYPE REF TO if_wd_window.
 
  lo_api_component  = wd_comp_controller->wd_get_api( ).
  lo_window_manager = lo_api_component->get_window_manager( ).
  lo_window         = lo_window_manager->create_window(
    window_name          = 'W_POPUP'
    message_display_mode = if_wd_window=>co_msg_display_mode_selected
    button_kind          = if_wd_window=>co_buttons_save
    message_type         = if_wd_window=>co_msg_type_none
    default_button       = if_wd_window=>co_button_save
    ).
  DATA:  l_api TYPE REF TO if_wd_view_controller.
 
  l_api = wd_this->wd_get_api( ).
" Subscribe to  button event
  lo_window->subscribe_to_button_event(
               button            = if_wd_window=>co_button_save
               action_name       = 'ON_SAVE " create method with this name in the Methods tab
               action_view       = l_api
               is_default_button = abap_true ).
 
  lo_window->open( ).

6 in ur ON_SAVE method , read the value entered in the input field using get_attribute method

u cn use the control wizard , press cntrl +f7 , n choose read context node/attribute and choose the attribute which is

binded to ur input filed , suppose we get the value lv_input

7 in ur view1 , get get the table's data in an internal table.

8 Bind the internal table with the Table UI.

select * from mara into table itab where matnr = lv_input .
DATA lo_nd_node  TYPE REF TO if_wd_context_node.
lo_nd_node = wd_context->get_child_node( name = wd_this->wdctx_node ).
lo_nd_node->bind_table( itab ).

// here in first vie node NODE is binded with table UI which is also binded to node in component controller

It shud solve ur problem

rgds,

amit
