<?xml version="1.0" encoding="utf-8" ?>

    <add key="PFUserName" value="[email protected]"/>
    <add key="PFPassWord" value="xxxxxxxxxxxxx"/>
    <add key="smtpClient" value="smtp.gmail.com"/>
    <add key="SmtpServerPort" value="587"/>

and am calling this configuration in my ascx.cs file as bellow

using System.Configuration;
namespace SendingMessage.ControlTemplates.SendingMessage
    public partial class SendingMessage : UserControl

        protected void btn1_Click(object sender, EventArgs e)
            string userName = ConfigurationManager.AppSettings["PFUserName"];
            string password = ConfigurationManager.AppSettings["PFPassWord"];
            string smtpClient = ConfigurationManager.AppSettings["smtpClient"];
            string smtpPort = ConfigurationManager.AppSettings["SmtpServerPort"];
                MailMessage mail = new MailMessage();
                SmtpClient SmtpServer = new SmtpClient(smtpClient);
                mail.From = new MailAddress("[email protected]");
                mail.Subject = "Test Mail";
                mail.Body = txt_mail.Text.Trim();
                SmtpServer.Port = int.Parse(smtpPort);
                SmtpServer.Credentials = new System.Net.NetworkCredential(userName, password);
                SmtpServer.EnableSsl = true;
                txt_mail.Text = "";
            catch (Exception ex)


but this above code is not working when am passing the configured data,so any one have any idea regarding my issue?
is there any other option which could be helpfull?

That is not how SharePoint works, web.config and app.config are features of web application and windows/console application respectively.

Below is what I can think of as alternative. Create your custom XML file or above file can also be used. You need to use module feature something to deploy your XML file to layouts folder which can go along with your ascx file.

From your ascx.cs file, use XML reader objects to read this XML file and Query required properties/nodes based on XML. Below can used to read XML document

XmlDocument doc = new XmlDocument();
doc.Load("c:\\temp.xml"); // path to your xml file from layouts...use http to read this...

Then read your nodes, you can also loop through all at once and store values in local variables...

XmlNode node = doc.DocumentElement.SelectSingleNode("/configuration/appSettings");

string text = node.InnerText;

Basically you need parse XML the way you are defining it..
