Using Alternate States to Select Multiple Values in a List Box with Different Attributes

[Josh_Good]

This video show how to use alternate states to select multiple values in a list box when the members of the list box have different attributes. In this example a list of hockey players is used to select players to fill each position on the team.  The QVW created in the video is included in this post.

Hi Josh,

Thanks for posting this document. it was very useful for me.

I have question about selecting multiple values from a list box and passing it through.

For e.g.:  If I have to select more than 1 person from the Left Wings list;

how should we change the expression on the actions to achevie this?  I tried with the open and close brackets,but it dint help.

Thank you!!

This expression should work:

='(' & Concat(DISTINCT {[Left Wing]}  Player, '|') & ')'

The results you are looking for is to have the expression resulting in:

(Name1|Name2|Name3)

Josh,

I too tried the same initially but with this expression, it doesn’t read any selections from the list box,

Could you please take a look at it?

Thanks

Hi Suresh,

The reason it isn't work is because the players have spaces in their names.  So you need to replace the space with a single character wild card - the question mark - '?'

Try this expression for your selection:

=replace('(' & Concat(DISTINCT {[Left Wing]}  Player,   '|') &  ')',' ','?')
