Disable/Enable checkboxes in checkbox Group

[Former Member]

Hi Experts,

I have a check box group on my view and is binded to a table of texts.

My requirement - based on first check box (If first check box is checked/true), check(Make true) second check box and disable the second check box for editing.

I am able to check(make the value true) of second check box but not able to disable it.

Please guide me in archiving the above requirement (Enable/disable).

Thanks in Advance.

I had to capture the selected checkboxes then disable the required checkboxes and mark the checks again.

Hi Radhika,

I did the steps as you mentioned, the second check box is getting disabled. but the checked values of both the check boxes is getting reset (to false/unchecked).

Please let me know if I am missing any steps

Thanks in advance

Hi, Place the following code in the onToggle method for the checkbox.

DATA: ls_stru TYPE wd_this->element_cn_radiobtn.
  DATA: lt_data TYPE wd_this->elements_cn_radiobtn,
        ls_data TYPE wd_this->element_cn_radiobtn.

*context_element = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).
  context_element->get_static_attributes( 
                  IMPORTING static_attributes = ls_stru ).

  DATA lo_nd_cn_radiobtn TYPE REF TO if_wd_context_node.
  DATA lo_el_cn_radiobtn TYPE REF TO if_wd_context_element.

*  navigate from <CONTEXT> to <CN_RADIOBTN> via lead selection
  lo_nd_cn_radiobtn = wd_context->get_child_node(
                     name = wd_this->wdctx_cn_radiobtn ).

  DATA: checked TYPE string.

  checked = wdevent->get_string( 'CHECKED' ).

  IF checked EQ 'X'.
" get the contents of t he node(i.e all the checkbox values)
    lo_nd_cn_radiobtn->get_static_attributes_table(
     IMPORTING table = lt_data ).

    LOOP AT lt_data INTO ls_data.
      lo_el_cn_radiobtn = lo_nd_cn_radiobtn->get_element( index = sy-tabix ).
      IF ls_data-ca_key NE ls_stru-ca_key.
        " disable the fields
        lo_el_cn_radiobtn->set_attribute( EXPORTING name =  'CA_EDITABLE'
          value = abap_true ).
      ENDIF.
      " mark the fields as checked
      lo_el_cn_radiobtn->set_selected( abap_true ).
    ENDLOOP.

  ENDIF.

Hi Radhika,

Thanks for your reply.

I am not sure of how I have bind the second checkbox to an attribute of type boolean,because i am using a checkbox group and not a multiple checkboxes independently. and I may have more checkboxes based on the number of node elements.

I have binded only the texts to a node-attribute of type text. and i dont see a checked property in the list of properties for checkbox group

Hi, If you have used a checkboxgroup, follow this approach, 1. Under your node, create an additional attribute 'READONLY' type boolean. 2. Bind this attribute to the readonly property of your checkbox group

" Code in WDDOINIT
  DATA: itemlist TYPE if_viewname=>elements_nodename,
        w_list LIKE LINE OF itemlist.

  w_list-ca_key = 'Black'.
  w_list-ca_editable = abap_false. "initially keep the checkbox enabled
  APPEND w_list TO itemlist.
  w_list-ca_key = 'White'. 
  w_list-ca_editable = abap_false. "initially keep the checkbox enabled

  DATA: items_node TYPE REF TO if_wd_context_node.

  items_node = wd_context->get_child_node( name = `CN_RADIOBTN` ).
  items_node->bind_table( itemlist ).

" now implement  the OnToggle event, and based on your condition pass abap_true to disable the required checkbox

Hi,

Bind the readonly property of your second checkbox with an attribute type boolean, and when you want to disable it pass abap_true or X.

Note: if your checked property is already bound to an attribute of type boolean you can use the same attribute to bind the readonly property, so when you make it as X it will be disabled at the same time.

Radhika.
