Hi Shyja ,

First we should create attribute(ENABLE) with data type as WDY_BOOLEAN , then bind that attribute to button's Enable property,After that go to WDDOINIT() method in View , Write the following code,

DATA:

elem_context TYPE REF TO if_wd_context_element,

stru_context TYPE if_v_main=>element_context ,

item_enable LIKE stru_context-enable.

• get element via lead selection

elem_context = wd_context->get_element( ).

• get single attribute

• elem_context->get_attribute(

• EXPORTING

• name = `ENABLE`

• IMPORTING

• value = item_enable ).

CALL METHOD elem_context->set_attribute

EXPORTING

VALUE = 'X'

name = `ENABLE` " Attribute Name

.

After that we should create one event for that button ,

then we should write below code for that event method,

DATA:

elem_context TYPE REF TO if_wd_context_element,

stru_context TYPE if_v_main=>element_context ,

item_enable LIKE stru_context-enable.

• get element via lead selection

elem_context = wd_context->get_element( ).

• get single attribute

• elem_context->get_attribute(

• EXPORTING

• name = `ENABLE`

• IMPORTING

• value = item_enable ).

CALL METHOD elem_context->set_attribute

EXPORTING

VALUE = ' '

name = `ENABLE` " Attribute Name

.

Hi ,

In WDDOMODIFY view

try the following:

DATA : obj_btn TYPE REF TO cl_wd_button.

obj_btn ?= view->get_element( 'button' ).

if ( first_time == abap_false ).

CALL METHOD obj_btn->set_enabled(

EXPORTING

value = abap_false ).

endif.

Thanks,
