Multiple selection with ItemListBox

[former_member182429]

Hi all, I have an ItemListBox in my WD application, which I have used a supply function to provide data to populate the listbox.

Now I have this snippet of code (generated with the Code Wizard) that is supposed to read the value that the user selects:

DATA lo_nd_node_mynode TYPE REF TO if_wd_context_node.

DATA lo_el_node_mynode TYPE REF TO if_wd_context_element.

DATA ls_node_mynode TYPE wd_this->element_node_mynode.

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

lo_nd_node_mynode = wd_context->get_child_node( name = wd_this->wdctx_node_mynode ).

• get element via lead selection

lo_el_node_mynode = lo_nd_node_mynode->get_element( ).

• get all declared attributes

lo_el_node_mynode->get_static_attributes(

IMPORTING

static_attributes = ls_node_mynode ).

Here comes the problem: When "multipleSelection" is unchecked, I am able to retrieved the single value selected from "ls_node_mynode".

However, when I check multipleSelection, ls_node_mynode gives nothing.

What gives? I know this is really a simple question, but I am unable to find anything remotely useful in the documentation for this. Thanks in advance.

Hi HSKOK,

Please try to understand following code it will solve your problem.And its a running code so u can use it .

data lt_elements type wdr_context_element_set.

data lr_node type REF TO if_wd_context_node.

data node_element type ref to IF_WD_CONTEXT_ELEMENT.

data it_type type wd_this->elements_ZPROMOTIONS.

data wa_type type wd_this->element_ZPROMOTIONS.

lr_node = wd_context->get_child_node( 'ZPROMOTIONS' ).

lt_elements = lr_node->get_selected_elements( ).

loop at lt_elements into node_element.

node_element->get_static_attributes( importing static_attributes = wa_type ).

append wa_type to it_type.

endloop.

Here you need to understand why above loop has been introduced

regards

Thank you, Abap WD and PG. I have resolved my question with help from both your answers.

Use this method of the interface node GET_SELECTED_ELEMENTS, and change the context to multiple selection.

You are getting only one record bcoz you are using get_static_attributes method, which will only retrun one row.

Hope it works.
