    If you write connection string in web.config file, then you can access it in all the web pages for the same application.
    I have written my connection string in web.config file as follows. You can edit the connection string according to your computer and server setting.

    <add name="connString" connectionString="data source=(local);initial
    catalog=Employee;integrated security=true"/>


    You can access this connection string in cs file as follows.
    string con= ConfigurationManager.ConnectionStrings["connString"].ConnectionString;

    SqlConnection conObj = new SqlConnection(con);
