Hello, Bhoopathi;

You should be able to view a report based on an OLAP cube through Visual Studio .NET if the database driver is available and if you do not try to change the location of the database at runtime. The location of the OlaP cube would have to be as it is saved in the report.

What version of Crystal Reports and Visual Studio are you using for your web application?
