0	Just see the below code so that it will solve your problem. If Web.Confi file, define a conntionString and give a name to it. see the below code:- <connectionStrings> <add name="NorthwindConnectionString" connectionString="Data Source=serverName;Initial Catalog=Northwind;Persist Security Info=True;User ID=userName;Password=password" providerName="System.Data.SqlClient"/> </connectionStrings> After that you use the below code to read the connectionString on every page. using System.Web.Configuration; public string DbConnection = ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString; See the links:- http://msdn.microsoft.com/en-us/library/ms178411.aspx http://stackoverflow.com/questions/5642474/setting-up-connection-string-in-asp-net-to-sql-server http://www.codeproject.com/Articles/301726/Web-config-File-ASP-NET If this helps you towards the solution, click on MARK IT AS ANSWER Happy Coding.

After that you use the below code to read the connectionString on every page.


using System.Web.Configuration;

0	So,you can make a class and in the constructor,you can fetch your connection-string from web.config file.Every time,if you make object of that class,then your connection string will be initialized. Sharmagoldi781, if this helps please login to Mark As Answer. \| Alert Moderator

0	Make a Base class and inherit it in derived class. In your base class,in constructor you can initialize connection string parameter. In Derived class,you can have all the CRUD operations. Once you call any method from derived class,then your base class constructor will be called and initialized, so you do not have to call the connection string. Please let me know.
