You have not included the namespace to the class that includes Common.
Right click on Common and see if you get a resolve option. Use that.

If you don't get it, mostly likely you need to add a reference to the dll.

Which error you got near Common?

Better use ConfigurationManager to get Connection String and store your connection String into Web.Config file in connectionString tag

Hi ,
BY THE WAY Common is class and maybe it doesn't exist :)
your problem in connection string try to use it like this.

XML

<connectionStrings>
    <add name="testConnectionString" connectionString="Data Source=.;Initial Catalog=test;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>

Code Behind

C#

protected void Page_Load(object sender, EventArgs e)
{
    DataReaderFromSqlAccess();
}

public void DataReaderFromSqlAccess()
{
    string strSql = "Select * from Emp_Details";
    try
    {
        using (SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString)
           )
        {
            using (SqlCommand cmd = new SqlCommand(strSql, cnn))
            {
                cnn.Open();
                using (SqlDataReader dr = cmd.ExecuteReader())
                {

                    while (dr.Read())
                    {

                       xxx =(String.Format("{0} {1}",
                          dr["empid"], dr["password"]));
                    }
                }
            }
        }
     
    }
    catch (Exception ex)
    {
      //  errorLabel.Text = ex.Message;
    }
}

Best Regards
