Did you able to connect to SQL Server through SQL Server Management Studio(SSMS) with same credentials?
I think password is incorrect or you do not have access to that database...
Can you post Error code (SQL STATE)?

Refer this link it might help you

Hi Raja,
While adding connection to Visual Studio have you clicked on "Test Connection" button
Server Explorer in VS2010 --> Right Click on it and select Add Connection
-- >Enter Server Name
--> select Database name from drop down list under "connect to a database"
--> click on Test Connection

Then let me know the what you got whether succeed to connect or error...

The error was
A network- related or instance -specific error occured while establishing a connection to SQL server.The server was not found or was not accessible.Verify that the instance name is correct and that SQL server is configured to allow remote connections[Provider:Named Pipes Provider ,error: 40 - Could not open a connection to SQL Server]

Hai Bandi
In your last post you have told to connect a based on a server name in Server name
In V.S 2010 Server Explorer my server name is displayed evenly


The options i saw

Data Connections

Servers
<>C
SharePoint Connections

in SSMS run the following command
[code]SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')[/code]

This query should get you the server name and instance name :[code]SELECT@@SERVERNAME,@@SERVICENAME[/code]
In the server explorer in VS2010 add servername/instancename as servername while add connection
