Selection-List: Getting multiple values

[Kladkul]

I'm working with a selection-list and I'm allowing users to select multiple values in the list. How do I get all of the selected values into a variable?

I can see there is an IS-SELECTED() method but I can't seem to get it to work. Does anyone know how to get this working correctly?

Just got a lightbulb:

    ASSIGN v-list = sel-list:PRIVATE-DATA. 
    DO v-cnt = 1 TO NUM-ENTRIES(v-list):
        v-selected = sel-list:IS-SELECTED(v-cnt). 
        IF v-selected THEN DO: 
            IF v-hosts = "" THEN 
                ASSIGN v-hosts = ENTRY(v-cnt,sel-host:PRIVATE-DATA).
            ELSE 
                ASSIGN v-hosts = v-hosts + "," + ENTRY(v-cnt,sel-host:PRIVATE-DATA).
        END.
    END.

Looks like this will do what I need.

Greetings,
I am confused though as long as you have worked it out that`s all that matters.
The syntax you supplied seemed only to use the private-data attribute - this is not seen on the interface.
???

Well, I needed the private-data of the items that the user selects. The same would've worked if I used the LIST-ITEMS attribute instead of PRIVATE-DATA.

 

[lord_icon]

The PRIVATE-DATA attribute, can be anything - it is not used
You can even set set the sttribute to pants if you wanted.
objectNameRIVATE-DATA = "pants.
The user does not need to know this value.

It seems like you aren't understanding the question, either way it doesn't matter. The code does what I need it to

The way I understand it, the OP has sent the private data elsewhere, and just wants to enquire on the private data of the entries selected by the user. Makes sense to me.

    ASSIGN v-list = sel-list:PRIVATE-DATA. 
    DO v-cnt = 1 TO NUM-ENTRIES(v-list):
        v-selected = sel-list:IS-SELECTED(v-cnt). 
        IF v-selected THEN DO: 
            IF v-hosts = "" THEN 
                ASSIGN v-hosts = ENTRY(v-cnt,sel-host:PRIVATE-DATA).
            ELSE 
                ASSIGN v-hosts = v-hosts + "," + ENTRY(v-cnt,sel-host:PRIVATE-DATA).
        END.
    END.

Looks like this will do what I need.

Just a little tip I've found (hope I'm not teaching you to suck eggs), but to get a comma delimited list, the following code is much simpler to read IMO It removes the need for the check for a blank v-hosts.

ASSIGN v-hosts = v-hosts + MIN(v-hosts,",") + ENTRY(v-cnt,sel-host:PRIVATE-DATA).
