  For a single select parameter, I can display the value chosen on the actual report by using Parameters!Param.Value. When I do this with a multi-select parameter, it just prints out System.Object[]. Is there a way to print all selections in a comma separated string?

  Hi Jonathan,

  The Multivalue parameter stores the parameter values as an Object Array therefore displaying the same on the report displays ‘System.Object[]’.

  In order to display the selections in a comma-separated string you can write your own method in the ‘Script’ section of your report which takes a ‘System.Object[]’ type of parameter, converts and concatenates each string with a comma, and returns the resultant string. After which you can call this method from your report using ‘=Code.YourMethod(@ReportParameter1)’ and it will display all your selected values in a comma-separated string.

  Please find attached a sample implementing the same.

  Regards,
