Get UI element ID

[Former Member]

Hi,

I'm trying to get the element ID.

Ex: I'm having a inputfield with id = 'input1'.

at runtime i want to hide the fields depeding the id.

So i need to get the id.

I used cl_custom_event to get the id.

But getting the type conflict.

Can u help me out.

Thanks.

hi suba,

If you have already created an input field element with id 'INPUT1' at design time, first access that particular element using the ID that you specified , then do the manipulations( visibilty :: hide) there however you like..

source code would be as follows..

METHOD wdmodifyview.

DATA : lr_input1 TYPE REF TO cl_wd_input_field.

lr_input1 = view->get_element (

exporting

id = 'INPUT1'

).

now u have reached to that particular element where u can change it's properties.

first get the visibility property of this element.

data: lv_visible Type Ref to wdui_input_field_visible.

lv_visible = lr_input1->get_visibile().

lr_input1->set_visible(

importing

value = IF_WDL_STANDARD=>INPUTFIELDVISIBLE_NONE).

try this one.. and it should work....

best regards .

Hi Srini,

Thanks a lot for ur answer.

I welcome ur code example.

If we know the ID we are accessing the property.

But I want to get the ID dynamically.

Say for example, we are having 5 screen input fields.

once u fill data into the 1st field, u have to move the cursor to the 2nd field and it goes on....

So i would like to get the id dynamically.

Hi Suba

I think it's not a good design to hide some inputfield deponds on their id in WDDOMODIFYVIEW.

Webdynpro programming suggests that binding the UI elements's invisible property to a context attribute, and then change the invisible property in your actions.

You can bind your inputfield's invisible property to few groups,like Input1-20 bind to group1,Input30-40 bind to group2,and in your actions change group1 to abap_false or abap_true,it's the best way to handle UI elements.

Hi,

Follow the following steps:

1. You have to have a reference to the current view - a reference to an object of type IF_WD_VIEW. The is automatically available in the WDDOMODIFYVIEW event handler.

2. Use a code similar to the following.

 data: lr_container       type ref to cl_wd_transparent_container,
         lr_layout            type ref to cl_wd_layout,
         lr_text                type ref to cl_wd_text_view.

  lr_container ?= view->get_element( 'CONTAINER_NAME' ) .
  lr_layout ?= cl_wd_grid_layout=>new_grid_layout( container = lr_container ).
  lr_container->set_layout( lr_layout ).

  if lr_container->has_children( ) = 'X'.
    lr_container->remove_all_children( ).
  endif.

  lr_text ?= cl_wd_text_view=>new_text_view( text = l_msg design = 03 ).
  cl_wd_grid_data=>new_grid_data( element = 'Text' ).
  lr_container->add_child( lr_text ).

The above code has a reference to the current view in 'view' (it is written in WDDOMODIFYVIEW)

The reference to the transparent container UI element is retrieved, and a UI element of type TEXTVIEW is attached to the transparent container which has a grid layout.

Similarly, you can create and add other UI elements dynamically.

hi suba ram,

To the best of my knowledge if u want to get the ID of a view element , do the following

From the view element (input-field 1 (ID : INPUT1))

create and instance of ur INPUT-FIELD1, which is

data: LR_INPUT1 TYPE REF TO CL_WD_INPUT_FIELD1

DATA: lv_id TYPE string.

lv_id = LR_INPUT1->IF_WD_VIEW_ELEMENT~GET_ID().

It must work.....
