Need help with itemlistbox display

[Former Member]

I have an itemlistbox which I populate from a table. It's set to multiselect. I can pick and save the selections to a table with no problems. What I can't seem to figure out is how to get the itemlistbox to set the index(s) based on the data. When the itemlistbox loads nothing is selected. How can I pass a table of records to the itemlistbox so that they appear selected?

Hi,

Web Dynpro selection logic is stored in context objects - node and elements. You can use method set_selected of node or element to select specific items.

For example:

DATA: lr_node TYPE REF TO if_wd_context_node,

         lt_rows TYPE wdr_context_element_set,

         lr_elem TYPE REF TO if_wd_context_element.

   lr_node = wd_context->get_child_node( name = 'TEST_NODE' ).

* Set first element selected 

   lr_node->set_selected( flag = 'X' index = 1 ).

* Set all elements selected looping at index

   DO lr_node->get_element_count( ) TIMES.

     lr_node->set_selected( flag = 'X' index = sy-index ).

   ENDDO.

* Set all elements selected looping at element reference

   lt_rows = lr_node->get_elements( ).

   LOOP AT lt_rows INTO lr_elem.

     lr_elem->set_selected( flag = 'X' ).

   ENDLOOP.

Thanks a million. I just couldn't seem to figure it out yesterday but that's exactly what I needed!

Hi,

In addition to what Sergey said you can also get the value of each attribute and set the flag depending on some business logic.

For example

LOOP AT lt_rows INTO lt_elem.

       lt_elem->get_attribute(

                 EXPORTING name = 'ID'          "Attribute name          

                 IMPORTING value = l_value ).  "Attribute variable

* You can put some business rules here to check for which rows you would like pre-select

       IF l_value CS 'A'.

          lt_elem->set_selected( flag = 'X').

       ENDIF.     

ENDLOOP.
