Parameter is missing a value ssrs 2008

Question

I have a parameter of integer datatype which is hidden. When i run the report, report gives me an error

Parameter X is missing a value

Answer 1

Assuming you had the same issue as I had, trying to run the report on a web page using a ReportViewer component, I managed to fix that issue by adding a null parameter before rendering the report:

C# code:

var parameters = new List();
parameters.Add(new ReportParameter("ParameterName", (string)null));
ReportViewer1.ServerReport.SetParameters(parameters);

Hope that will help
