Hi Kiran,

Check if you have done the following steps:

- create an onselect method for drop down.

- create a context attribute of wdy_boolean type and bind it with the enabled property of the button.

- in the onselect method of the drop down, read the attribute that is binded to the drop down.

Check if it is not initial, set the value of the attribute as 'X'.

If still it is not working, Put a break point in the onselect method and see if that method is getting triggered.

Sorry, I didn't understand your question. Do you want to display the selected value in the text view?

Hi Kiran,

Refer this code

method ONACTIONONSELECT .

      DATA lo_nd_cn_visa TYPE REF TO if_wd_context_node.

    DATA lo_el_cn_visa TYPE REF TO if_wd_context_element.
    DATA ls_cn_visa TYPE wd_this->element_cn_visa.
    DATA lv_ca_visa TYPE wd_this->element_cn_visa-ca_visa.

*   navigate from <CONTEXT> to <CN_visa> via lead selection
    lo_nd_cn_visa = wd_context->get_child_node( name = wd_this->wdctx_cn_visa ).

*   get element via lead selection
    lo_el_cn_visa = lo_nd_cn_visa->get_element( ).
*   @TODO handle not set lead selection
    IF lo_el_cn_visa IS INITIAL.
    ENDIF.

*   get single attribute
    lo_el_cn_visa->get_attribute(
      EXPORTING
        name =  `CA_visa`
      IMPORTING
        value = lv_ca_visa ).

if lv_ca_visa eq 'X'. " I am assuming that the value which is selected in drop down has a key 'X'.

    DATA lo_el_context TYPE REF TO if_wd_context_element.
    DATA ls_context TYPE wd_this->element_context.
    DATA lv_ca_enable TYPE wd_this->element_context-ca_enable.

*   get element via lead selection
    lo_el_context = wd_context->get_element( ).

*   @TODO handle not set lead selection
    IF lo_el_context IS INITIAL.
    ENDIF.

*   set single attribute
    lo_el_context->set_attribute(
      name =  `CA_ENABLE`
      value = 'X' ).

    endif.

endmethod.

I hope it helps.
