Question

How can I pass multiple parameter values to Reporting Services Report c#

Asked by: wint100

I have the code below to programatically render a report in Reporting Services 2008 and pass the parameters needed.

One of the parameters can accept multiple values. How can I pass these from the C# code? I've tried passing Comma seperated values (1, 2, 2 etc), but is throws an exception.

The parameters are selected from an SQL database in varchar(50) format.

if (_parameters.Length > 0)
                {
                  parameters[0] = new BECScheduler.rsExecService.ParameterValue();
                  parameters[0].Label = "";
                  parameters[0].Name  = "SDate"; 
                  parameters[0].Value = sDate;
                  parameters[1] = new BECScheduler.rsExecService.ParameterValue();
                  parameters[1].Label = "";
                  parameters[1].Name = "EDate";
                  parameters[1].Value = eDate;
                  parameters[2] = new BECScheduler.rsExecService.ParameterValue();
                  parameters[2].Label = "";
                  parameters[2].Name = "TLInstance1";
                  parameters[2].Value = TLInstance1;
                  parameters[3] = new BECScheduler.rsExecService.ParameterValue();
                  parameters[3].Label = "";
                  parameters[3].Name = "TLInstance2";
                  parameters[3].Value = TLInstance2; 
                }

How did you try passing in the list?

Like this?

(and for the record - I haven't had to do this before, but I'm just thinking about how SSRS understands multivalue parameters)

parameters[3] = new BECScheduler.rsExecService.ParameterValue();
parameters[3].Label = "";
parameters[3].Name = "TLInstance2";
parameters[3].Value = "1, 2, 3";

 

by: wint100Posted on 2009-07-12 at 23:52:21ID: 24837627

Yes thats right, with comma then a space before the next value.

 

by: rob_farleyPosted on 2009-07-13 at 00:00:06ID: 24837650

Actually, do this... populate an array of strings (called yourarray here), and then make the parameter using a different constructor, like this:

ReportParameter[] parameters = new ReportParameter[3];
....
parameters[3] = new ReportParameter("TLInstance2", yourarray);

Hope this helps...

Rob
