report and subreport parameters

[Ivan]

Hi Telerik team,

I need to pass some of my entities as parameters to my report and then propagate them down to my subreport.

i tried something like this: 

var instanceReportsource = new InstanceReportSource();
instanceReportsource.ReportDocument = new InventoryReport
instanceReportsource.Parameters.Add("location", location); 
instanceReportsource.Parameters.Add("filters", filters);
 
ReportViewer2.ReportSource = instanceReportsource; 
ReportViewer2.RefreshReport(); 
ReportViewer2.Update();

The problem is when i hook to the item binding events I see no parameters in the processing items. 

What am I doing wrong. What is the best way to pass the entities to the report and subreport?

thanks.

OK, I now saw that the parameters can only be of simple types so I guess parameters wont do it. 

Before i elaborate here is my scenario. 

a report  contains a recursive subreport (source is the same as the top level report)
i use databinding reportsource with a static method to pass data to the subreports
hooking to the needdatasource event does not work because of the report source already assigned to the top level report. 

I tried creating properties in my report to which i can assign the entities but because of the static data method for the subreport i cannot access them.

Do you have any suggestions?

thanks.

Defining properties for the entities on the report and using item.ItemDefinition.Report actually works.
