Hi,

Declare one Attribute in Context node which is of type WDUI_VISIBILITY.

Now bind the above declared attribute with the value property of your UI element.

Now By using CODE wizard ... select the SET radio button and then choose the attribute which is created in Context node...it will generate some predefined code which is shown below

For Ex:

node->set_attrubute(

------

value = lv_attribute

).

Visibility Criteria:

If you want to hide the UI element use

lv_attribute = 01.  (value for hiding) just above the auto generated code which is shown above.

----------------------------------------

If you want to  unhide/show the UI element use 

lv_attribute = 02. (value to show UI element) just above this auto generated code which is shown above.

You can use this procedure based on button clicks; Like, On click of BUTTON you can display some text elements or TEXTEDIT etc...

hi ,

bind the VISIBLE property of the UI element with a context attribute created in the CONTEXT tab. This context attribute should be of type WDUI_VISIBILITY

u can refer this code

wd_context->set_attribute( name = '<attribute name>' value = if_wdl_core=>visibility_visible )." to make it visible.
 
wd_context->set_attribute( name = '<attribute name>' value = if_wdl_core=>visibility_none ). "to make it invisible

Hi Rahul

Step-1 : Declare a attribute of type WBY_BOOLEAN in the Context of the view.

Step-2 : Bind these attribute to the Visible Property of the Interactive Form

Step-3 : In Code set the attribute value to ABAP_FLASE by using SET_ATTRIBUTE where ever u need

And Interactive Form is Invisible.....!!!!!!

Hi,

Bind the Interactive Form Ui element Visibile property to an attribute created in context of type wdy_boolean.

Now based on your condition set this attribute to true or false and control the visibility.
