navigation list

[former_member206760]

Hi ,

I am working on a navigation list example where ONSELECT of an entry in the list corresponsding values should be populated in the internal table.

so i have context like

context

+ navi_list ( leadselection Yes singleton No )

++ Navi_rec_node ( recursion node )

++ TEXT

++ SELECTABLE

++ CARRID

++ CONNID

data CONTEXT_ELEMENT TYPE REF TO IF_WD_CONTEXT_ELEMENT.

DATA ls_navi_list TYPE wd_this->element_NAVI_LIST.

DATA lo_nd_n1 TYPE REF TO if_wd_context_node.

• Get key information for selected navigation list entry

break-point.

lo_nd_n1 = wd_context->get_child_node( name = 'NAVI_LIST' ).

• get element via lead selection

context_element = lo_nd_n1->get_element( ).

context_element->get_static_attributes(

IMPORTING

static_attributes = ls_navi_list ).

but i am not able to get the selected element in the internal table

hi,

in OnSelect event handler , wdevent object has a parameter context_element.

Please check that in debug if that is filled.

Hi Bhaskaran,

I checked the value of context_element in debug...

it is

i think it is 0..

i tried using the below classes and found that my lead selection is not working ...it is always 1 ..eventhough i select 3rd item in the naviogation list...how do i correct this

CALL METHOD wdevent->get_context_element

EXPORTING

name = 'CONTEXT_ELEMENT'

RECEIVING

value = context_element. " getting the clicked line

data lv_index type i.

CALL METHOD lo_nd_n1->GET_LEAD_SELECTION_INDEX

RECEIVING

INDEX = lv_index.

No, it is not zero. It is bounded,it is object. You need not have to get the lead selection etc.

Just insert context_element of the type ref to if_wd_context_element as importing parameter.

use

context_element->get_static_attributes( ) method.

hi bhaskar,

many thanks for your help....it is working now....one final question and then you would have solved my problem fully..

why do i do not need to get the lead selection etc....why did just specifying the paramter context_element in importing worked??

i had already declared it within the code then why did not it work

Naviagtion_list has only onSelect event, it does not have lead_selection event as in TABLE UI.

However it has id,context_element standard parameter filled on onSelect event.

> i had already declared it within the code then why did not it work

If you mean this code shown below then i would expect that you have context_element reference.

CALL METHOD wdevent->get_context_element

EXPORTING

name = 'CONTEXT_ELEMENT'

RECEIVING

value = context_element.

Hi Tarang,

Code is correct.

What is your problem, what you want to do exaclty. Why you used recursion node?? here

by using this..

context_element->get_static_attributes(

IMPORTING

static_attributes = ls_navi_list ).

Now in ls_navi_list you will get selected record.

cheers,

Kris.

Hi ,

I am having a navigation list on selection of a particular item in the list the corresponding details should be displayed in a table..

i am using recursion node because in the SAP PDF following is mentioned

"Create a recursion node (name: NAVI_REC_NODE) as a sub node

of NAVI_LIST. The recursion node has to repeat the structure of node

NAVI_LIST".

Hi Tara,

For your requirement no need to create recursion node. just create node with attributes you will reach your

requirement.

Cheers,

Kris.

recursion node is needed for navigation list UI element

if i do not use it i get a dump saying recursion node is needed
