Answer / d0tnetf0x

In web.config,we have to give connection to database by add
key which is given in application setting tags.as

<appsettings>
<add key="constr" value="Data Source=SQL-PC;Initial
Catalog=sampledb;User ID=sa;password=password "/>

</appsettings>

//under value we have given the database which is connected.
here under ----data source=servername
intial catalog=database name
user id=username of the database(if give)
password= password(optional)

to use this connection we use configsetting or we caneven
directly give it in sqlconnection

sqlconnection conn=new sqlconnection
(configurationsetting.appsettings("constr"))
here constr is the key we added in application settings to
identify it in web.config
[this connection we used by declearing in web.config]

with out declearation:-
sqlconnection conn=new sqlconnection("Data Source=SQL-
PC;Initial Catalog=sampledb;User ID=sa;password=password ")

better process is useing connection by declearing in
web.config
