Debby,
You can pass in the ServerName and Database in the URL like this:
You need to have ReportViewer first and set its ReportServerURL property first:
Then do this in your code. you need to put your own server Name and database name and the path.
ReportViewerS1.ReportPath =
String.Format("/MyReportsFolder/ReportName&ServerName={0}&DatabaseName={1}", "Dev","Northwind")
Hope that helps.
