Code behind:The connection string settings in the config file has been made as per in the below snippet.It contain server and data base name.Before going to add this code we have to create a connection to database in web.config file. Here my connection name is "OrderDetailsConnection".
<appSettings> <connectionStrings> <add key="OrderDetailsConnection" value="server=bhaskar/SQLEXPRESS;database=Order_Db;uid=bhaskar;password=br123;" /> </connectionStrings> </appSettings>

}
}
//In the above code i have used to delete the records using "IN" in sql command.By using this we can delete the all records with in the list.Keep coming to get latest updates
