Database retrieval is not visible in the webpage.

Hi,
I could be able to connect to the database and the connection is success when ever I click the Test Database connection but it is not displaying any information from the DB tables.

I am getting this when I try to configure the ASP.NET  configuration.
----------------------------------------------------------------------------------------
Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.

but in fact I created the database connection and put the exact connection string but it is not displaying any information from the tables.

I have attached the web.config file code as well.
-------------------------------------

Thanks
