Hi every UI Element has the Option

Visible or enabled.

You must define a Binding whith an context atribute for example FORMULARUI ( Typ: WDY_BOOLEAN)

And over the Method (Button klick) you can add something like this:

* get element via lead selection

  lo_el_bildschirm = lo_nd_bildschirm->get_element(  ).

* set single attribute

  lo_el_bildschirm->set_attribute(

    EXPORTING

      name =  `FORMULARUI`

      value = space ).

Value = space or Value = ' '  meanes off

Value = 'X' means on

hope this helps

got it work by using below sample code.

data: id type string.

*--To read id of button

   id = wdevent->get_string( 'ID' ).

   check wd_comp_controller->g_view is BOUND.

   DATA: lr_detail_group        type ref to cl_wd_group,

         lt_group_children      type wd_tr_uielement.

* get a pointer to the detail group

   lr_detail_group ?= wd_comp_controller->g_view->get_element( 'bowled' ).

* get children of group

   lt_group_children = lr_detail_group->get_children( ).

   read table lt_group_children

        with key table_line->id = id

        transporting no fields.

   if sy-subrc = 0.

***delete selected button

     lr_detail_group->remove_child( index = sy-tabix ).

   endif.

Thanks,

Ratna
