    Hi. 

    You can split the string in the receiving business rule by delimiter e g comma

    Dim split as String() = args.NameValuePairs.XFGetValue("ParamCC").Split(",")

    Then loop through rresults to get each selection e.g

    For Each param As string in split

         ' Do Something 

    Next

Thanks Seburn.I tried the suggestions provided and it works partially.Means when list of members were passed in ParamCC, it works only for the first parameter.

Dim split as String() = args.customcalculateargs.NameValuePairs.XFGetValue("ParamCC").Split(",")

For Each param As string in split

      api.logmessage(param ) ( Im able to print each param)

     ' Do Something (but it works only for first parameter passed)

OK. I think you need to check you are passing in the param value via button AND DM step with square brackets around the parameter (see above). This behavior sounds like you are only picking up the first comma separated value  square brackets should fix 🙂

 

E.g button

seq_name}{ParamCC=[|!ParamA!|]}

E.g DM step

ParamCC=[|!ParamA!|]

    E.g button

    {seq_name}{ParamCC=[|!ParamA!|]}

    E.g DM step

    ParamCC=[|!ParamA!|]

      It is due to space created for each member.Resolved using below line and it worked.

      Dim ParamCC as string = (args.customcalculateargs.NameValuePairs.XFGetValue("ParamCC")).Replace(" ","")

      Dim split as String() = ParamCC.Split(",")

      For Each param As string in split

            api.logmessage(param ) ( Im able to print each param)

           ' Do Something (but it works only for first parameter passed)

      Next

      Thanks

        Might be worth looking at String.Trim. Seems more appropriate and safer even if you don't 'expect' spaces in the middle of things.

        Edit: I misread above and assumed you were taking off the spaces after you pulled it apart with the comma split which you weren't. But maybe you should be?
