Dear Experts,
Problem : I am trying to make an attribute invisible through code.But its not getting invisible.
I created an attribute in view context and binded this attribute to an input field in view and then in the wddoinit method i wrote the following code to make it invisible but its not working....
DATA lo_el_vis TYPE ref to if_wd_context_element.
lo_el_vis = wd_context->get_element( ).
lo_el_vis->set_attribute_property(
exporting
attribute_name = 'VIS_INVISIBLE'
property = 1
value = space ).
Pls help....
Kind Regards
Sajid
Hi Sajid,
I have a context node by name NODE & 2 attributes under it. One is for binding to the input field and the other attribute ( name VISIBILITY) is of type WDY_VISIBILITY. I use this attribute for controlling the visibility of my input field. I specify a default value of 2 i.e, visible for this. (Check the domain values for WDUI_VISIBILITY) Now I create a button and within this button action handler I want to toggle between the input fields visibility & invisibility statuses. Check the code snippet below.
Regards,
Uday
method ONACTIONTOGGLE_VISIBILITY .
data: wd_node type ref to if_wd_context_node,
lv_value type wdui_visibility.
wd_node = wd_context->get_child_node( name = 'NODE' ).
*** Read the current value in context attribute VISIBILITY
wd_node->get_attribute( exporting name = 'VISIBILITY'
importing value = lv_value ).
*** Toggle between values 01 & 02 to toggle the visibile & invisible states of the inputfield
if lv_value = '01'.
wd_node->set_attribute( exporting name = 'VISIBILITY'
value = '02' ).
else.
wd_node->set_attribute( exporting name = 'VISIBILITY'
value = '01' ).
endif.
endmethod.

Hi,
Have you created the type of attribute as WDUI_VISIBILITY.
lv_visible = '01'. "InVisible "type wdui_visibility
CALL METHOD wd_context->SET_ATTRIBUTE
EXPORTING
VALUE = lv_visible
NAME = `VISIBLE`.
What is your requirement.

Hi ,
Your attribute should be type BOOLEAN or WDUI_VISIBILITY. Bind your attribute to the visible property of the of the input field and use this code.
DATA lo_el_vis TYPE ref to if_wd_context_element.
lo_el_vis = wd_context->get_element( ).
lo_el_vis->set_attribute_(
exporting
name = 'VIS_INVISIBLE'
value = abap_false ).
Hope it helps!
