[2005] Connection disposed, but I can still find my process on SQL Server, why?

Hi There,

I have already Disposed the SQLClient.Connection, the application is still running, I have stepped through the code, I know the connection is closed and disposed, also the command and data adapter.

But if I check on SQL Server, I can still see the process is running, can someone help me or explain to me why this is happening?
