SET_ATTRIBUTE_PROPERTY doesnt work

[Former Member]

Hi All,

I have a declared a node ABC cardinality 1:1 under the context of my view and under this node ABC i have an Attribute MARK type boolian.

in the layout, I have a UI element check box for which I have binded the attribute MARK.

Now I want to set the read_only property dynamically to this check box.

LO_ND_ABC = WD_CONTEXT->GET_CHILD_NODE( NAME =  WD_THIS->WDCTX_ABC ).

LO_EL_ABC = LO_ND_TRAVEL_DATA->GET_ELEMENT( ).

CALL METHOD LO_EL_ABC->SET_ATTRIBUTE_PROPERTY
     EXPORTING
       ATTRIBUTE_NAME = 'MARK'
       PROPERTY       = 3
       VALUE          =  'X'.

But the check box was not set with read_only property.

I have searched many threads and after which i am raising this problem here.

I have also tried SET_ATTRIBUTE_PROPS_FOR_ELEM and SET_ATTRIBUTE_PROPS_FOR_NODE aswel.. but nothing worked out..

Please help.

I don't want to create an attribute and bind it to read_only property of the check box in the layout.

Hi,

Try the below code in wddomodifyview( ) method of your view

data lo_check_box type ref to cl_wd_checkbox.

lo_check_box ?= view->get_element( 'CHECK_BOX_NAME' ).

if lo_check_box is bound.

     lo_check_box->set_read_only( value = abap_true ).

endif.

Based on your requirement modify the above code,

Regards,

Rama

Its working.....Really loved your answer...

I actually afraid of thinking people suggest me to go for searching some other links or will ask me to create attribute and bind it to properties.

Hi All

if you are facing the same situation and

If you want to make  SET_ATTRIBUTE_PROPERTY  to work follow the below additional steps

along with the points i mentioned in my initial question

1. goto checkbox in the layout

2. bind MARK againest to read_only property,

    when you are binding a popup opens which shows all the context nodes and attributes

    in the same popup you have a radio button

"Bind to the Property of the selected Attribute"   --  set it to read_only from the drop down

After this step SET_ATTRIBUTE_PROPERTY is working fine.
