Problems with ReportViewer and RDLC

[C a r l o s A n t o n i o]

Hello,

I have an ASP.NET application that contains reports. I am not allowed to
use Crystal, so I decided to use .NET's reporting tool. My problem is that
the report viewer does not show in the browser, neither I am receiving any
error messages. Below is the code. Any help will be really appreciated.

Thank you very much for your help.
