Validation in Popup

[Former Member]

Hi,

I'm creating a 2 Views and 2 windows.

In 1st view when pressing a button I'm showing 2nd view as popup.

I used

1. lc_window_manager to create window.

2.button_kind = if_wd_window=>co_buttons_ok

It is working fine.

I want to validate the data entered in the popup window.

For ex: if the 2nd view as a inputfield of type string.

User should enter only string, if number occurs error should be displayed.

How to validate the data in popup?

I remove the button_kind and tried adding a button UI element in 2nd view.

But on pressing the 2nd view, how can i close the popup and return to the 1st view?

Thankx,

Hi Suba,

you can try the below code to open or close the popup.

Provided u have to maintain a variable as boolean.

If there is error/noerror u have to update the variable.

data l_error type boolean.

data: l_api type ref to if_wd_view_controller,

l_window_ctlr type ref to if_wd_window_controller,

l_popup type ref to if_wd_window.

l_api = wd_this->wd_get_api( ).

l_window_ctlr = l_api->get_embedding_window_ctlr( ).

if l_window_ctlr is bound.

l_popup = l_window_ctlr->get_window( ).

if ( l_popup is bound and l_error = abap_false ).

l_popup->close( ).

else.

wd_this->open_popup( ).

l_popup->open( ).

endif.

endif.

Hope it will help u.

Thanks

Nithya,

I tried ur code, but again it is showing the error msg in View1.

I tired by adding a button in View2 and on pressing the button I'm validating the fields. If there is no error how can i close the View2 and get the View1?

Hi Suba,

To close the view:

  l_api TYPE REF TO if_wd_view_controller,
  l_window_ctlr TYPE REF TO if_wd_window_controller,
  l_popup TYPE REF TO if_wd_window.
  l_api = wd_this->wd_get_api( ).
  l_window_ctlr = l_api->get_embedding_window_ctlr( ).

  IF l_window_ctlr IS BOUND.
    l_popup = l_window_ctlr->get_window( ).
    IF l_popup IS BOUND.
        l_popup->close( ).
    endif. 
  endif.

Do this if validations are successfull.

Reema,

I worked on the code. it works fine.

But it is showing the error msg in the View1, but I need the error msg to be displayed in the view2.

You need to get the current view's view controller instance, and call the corresponding message manager. The following code will help.

data: msg type ref to if_wd_message_manager.
msg = wd_this->wd_get_api( )->get_message_manager( ).
msg->report_t100_message( ).

Hi,

What you can do is: use button kind ok....

in the 2nd view, do this:

in wddoinit

data:
  l_api type ref to if_wd_view_controller,
  l_window_ctlr type ref to if_wd_window_controller,
  l_popup type ref to if_wd_window.

l_api = wd_this->wd_get_api( ).

l_window_ctlr = l_api->get_embedding_window_ctlr( ).

if l_window_ctlr is bound.
  l_popup = l_window_ctlr->get_window( ).
  if l_popup is bound.
  l_popup->subscribe_to_button_event(
                        button = if_wd_window=>co_button_ok
                        button_text = 'Ok' "#EC *
                        action_name = 'OK_CLICKED'
                        action_view = l_api
                        is_default_button = abap_true ).
  endif.
endif.

now in actions, create an action of the name OK_CLICKED.

Under Methods, you will get an event handler by the name ONACTIONOK_CLICKED

In this event handler, you can do all the validations you need to.

If validations fail, show message

else, close the window
