Making the button disabled in the pop up window

Question

Hi experts,
I have created a pop up with button type as buttons_yesno. The pop automatically creates two buttons YES and NO
The pop up window contains two fields - Manufacturer and Description as input fields.
The requirement i need is -> till the user enters the data into both the input field i wanted the yes button to be disabled.
i have done the below code for the pop up to appear.
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            = 'YWD_CREATE_MANF'
                 title                  =
                  close_in_any_case      = abap_false
                   message_display_mode   = if_wd_window=>co_msg_display_mode_selected
                 close_button           = abap_true
                   button_kind            = if_wd_window=>co_buttons_yesno
                   message_type           = if_wd_window=>co_msg_type_none
                  default_button         = if_wd_window=>co_button_ok
lo_window->open( ).
is there any option to make the button disabled initially and then enable it when the user enters both the input field.
Regards,
Vinod

Hi,
When ever you create the popup, store the window reference globally.
Use the method - SET_BUTTON_ENABLED of if_wd_window based on the input field values.
Use the GET_ATTRIBUTE for that input field get the value into lv_value,
if lv_value eq initial.
lo_window->set_button_enabled
exporting
button = button id
is_enabled = abap_false.
else.
lo_window->set_button_enabled
exporting
button = button id
is_enabled = abap_true.
endif.
