Try adding a ';' after your UserID!

(BTW: Don't post user id and password to forums! It's a good idea to get into the habit of security: Rule 1 - never tell the whole world your password... :doh: )

You dont need Provider name for SqlClient as it connects to the Sql Server provider by default.

So your Connectionstring should be
"Data Source=VINAYAK-67DE19C\SQLEXPRESS;Initial Catalog=UA;User ID=sa;password=sulos;"

Change it with yours, and try to use
connection.Open() to open the connection, I hope it will be working.

Cheers

Solution 3

Just opening a connection is not going to pull the data for you.
You need to use a dataset or datareader.
