This is how you can provide DataSource information to report at runtime.

Example:

ObjectDataSource objAdventureWorks = new ObjectDataSource("MyData", "GetDataAddress");

objAdventureWorks.ID = "Adventureworks";

this.Controls.Add(objAdventureWorks);

this.ReportViewer.LocalReport.DataSources.Add(new ReportDataSource("AdventureWorks2000", "Adventureworks"));

I think this article should answer your question. I was experiencing the same error and Russell's work-around fixed it.
