[RESOLVED] Error Help Requested

I'm getting an error that says "Unrecognised tag prefix or device filter 'rsweb'.

I'm following along on a tutorial that is helping me display a report in a web form.  Can someone please look at this markup and let me know what I'm doing wrong?

you need to register reportview assembly to be able to use reportviewr control

add this at top of aspx page (after page directive)

<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>

or u can add assembly in web.config

note that, the version number could be 8.0/9.0/10.0 etc. based on what reportviewer assembly is present in u r machine

hope this helps...

Thank you very much.
