Hi,

For the visibillity of any element, there are two ways.

1. Binding with Context Attribute

- Create an attribute of type WDUI_VISIBILITY

- Bind this attribute with the 'Visible' Property of table

- set the value of this attribute from methods based on your condition

- To make visible, set the value of context attribute as '02' and to make invisible '01'.

2. In WDDOMODIFYVIEW method of the view

- Check if the condition for making the table visible is met

Check the post by rvanamala in the following thread for sample.

Hi,

Check the code which give you idea about visability of fields, but bind table and change according to your requirement.

DATA lo_nd_dctrl TYPE REF TO if_wd_context_node. " Node of DCTRL structure

DATA lo_el_dctrl TYPE REF TO if_wd_context_element. " Element of DCTRL structure

DATA ls_dctrl TYPE wd_this->element_dctrl. " Structure for DCTRL

DATA:lv_asn_ind TYPE wd_this->element_dctrl-asn_ind, " Variable of ASN fieldfor DCTRL

lv_bool TYPE wdy_boolean. " Variable of boolean field for DCTRL structure

DATA :wd_por_en TYPE REF TO cl_wd_checkbox. " Workarea to declare check box

• navigate from <CONTEXT> to <DCTRL> via lead selection

lo_nd_dctrl = wd_context->get_child_node( name = wd_this->wdctx_dctrl ).

• get element via lead selection

lo_el_dctrl = lo_nd_dctrl->get_element( ).

• @TODO handle not set lead selection

IF lo_el_dctrl IS INITIAL.

ENDIF.

lv_bool = abap_true..

CALL METHOD lo_el_dctrl->set_attribute_property

EXPORTING

attribute_name = 'ASN_IND'

property = if_wd_context_element=>e_property-read_only"if_wd_context_element~e_property-read_only

value = lv_bool.

wd_por_en ?= view->get_element('SN_CHKBOX').

CALL METHOD wd_por_en->set_enabled

EXPORTING

value = abap_false.

HI,

You need to create an antribute in the context , with type WDY_VISIBILE.

now bind the attribute with the table visible property , and the control its visibilty through code.

on click of the button event , call method set attribute ( name = 'abc' value = '1') for visible , and value -= 0 for hiding table.

You can create attribute and assign attribute to control and pass your values to the attribute in your component logic for visible and invisible.
