how to change visibility property of a context in wd abap

[arjun_thakur]

hi experts,

i have binded a context of wdui_visibility type to a ui element. now i want to change this visibilty property at run time. i have written the folling code:

data lo_nd_visible type ref to if_wd_context_node.

data lo_el_visible type ref to if_wd_context_element.

data ls_visible type wd_this->element_visible.

data lv_visibility like ls_visible-visibility.

• navigate from <CONTEXT> to <VISIBLE> via lead selection

lo_nd_visible = wd_context->get_child_node( name =

wd_this->wdctx_visible ).

• get element via lead selection

lo_el_visible = lo_nd_visible->get_element( ).

• get single attribute

lo_el_visible->get_attribute(

exporting

name = `VISIBILITY`

importing

value = lv_visibility ).

wd_context->set_attribute( EXPORTING name = 'VISIBILITY' value =

abap_false ).

but it is giving a rum time error. the erroe message is : No context named visibility found.

please can anyone provide me the correct code.

thank you.

Hi

Since you are accesing the node containing the 'VISIBILITY' attribute you can use the following method to set the value

lo_el_visible->set_attribute(

exporting

name = `VISIBILITY`

value = 01 ). ""01 - none,02-visible

and remove this code

wd_context->set_attribute( EXPORTING name = 'VISIBILITY' value =

abap_false ).

Regards

we should not hard code the values, it is better to use the constants supplied by the framework

[abhimanyu_lagishetti7]

You have mis-spelled the context attribute name VISIBILITY please check.

and the possible values are ( not abap_false and true )

if_wdl_core=>visibility_visible

if_wdl_core=>visibility_none
