I am not sure it will works for you or not but I always use following code to get connection string..

C#

protected string ConnectionString
{
get
 {
 return WebConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
 }
}
using (var connection = new SqlConnection(ConnectionString))
    {
        connection.Open();

         ----------body----------

        connection.close();
    }

Wherever you want connection string in web form use connection variable.
