Hi,

1)Bind ur fields with the context attribute of type WDY_BOOLEAN. There is a value propery of ur field. Bind that property.

2) Now create a action for ur button . In the method OnAction of the button , u need to set the attribute , to '01' or ABAP_FALSE to make the field non editable

3) for this, u can go to code wizard. press control+f7. choose the radio button to read/set the attribute

  DATA lo_nd_cn_editable TYPE REF TO if_wd_context_node.
  DATA lo_el_cn_editable TYPE REF TO if_wd_context_element.

* navigate from <CONTEXT> to <CN_EDITABLE> via lead selection
  lo_nd_cn_editable = wd_context->get_child_node(
  name = wd_this->wdctx_cn_editable ).

* get element via lead selection
  lo_el_cn_editable = lo_nd_cn_visiblesuper->get_element(  ).

* set single attribute
  lo_el_cn_editable->set_attribute(
    EXPORTING
      name =  `CA_EDITABLE`
*    IMPORTING
      value = '01' ).
// context attribute ca_editable under the context node cn_editable
// set the attribute to '01' for dispaly mode

Similarly in the OnAction method of ur Create button , u can go to the code wizard and choose to read the context node , which is having all the attributes . there u can choose the method invalidate()

        lr_node = wd_context->get_child_node( name = lv_node ).
        lr_node->invalidate( ).

regards,

Hello Deepika,

Please share your piece of code which you are writing in display action.

hi,

when using the set_attribute method don't use the IMPORTING parameter ..

for the WDY_BOOLEAN attribute , use the value ' ' for non editable and 'X' for editable..

instead of '01' and '02' as it is used for visibility and is a correction to the earlier post ..

Hi,

First declare an attribute of type char1 with a default value as X.

Go to the input field. In the properties tab you can set the visibility of the field. Bind that field with the created attribute.

As the default value is X, initially all the fields will be editable.

When you click on display button, write the below code.

DATA lo_nd_nd_vis1 TYPE REF TO if_wd_context_node.
  DATA lo_el_nd_vis1 TYPE REF TO if_wd_context_element.
  DATA ls_nd_vis1 TYPE wd_this->element_nd_vis1.
  DATA lv_vis LIKE ls_nd_vis1-vis.

 lo_nd_nd_vis1 = wd_context->get_child_node( name =
wd_this->wdctx_nd_vis1 ).


  lo_el_nd_vis1 = lo_nd_nd_vis1->get_element(  ).


  lo_el_nd_vis1->set_attribute(
      name =  `VIS`
      value = ' ' ).

Hello,

First of all to make a field editable or display only You need to bind the read only property not the visiblity.

Visiblity property takes value '01' or '02'.

It will give you the step by step procedure in using the visibility and enable property.

Hi Taragini,

This can be done easily with the following steps:

1. Create a view context attribute READ_ONLY_FLAG with type boolean.

2. For the input fields of your interests, associate the context attribute with the "readOnly" property.

3. In the action for Display button, set the value of READ_ONLY_FLAG contribute to 1. Vice versa, set READ_ONLY_FLAG to 0 in onActionCreate. Also clear the data in the same action.
