Code for How to Send SMS in Windows Phone 7

Today, in this article let's play around with one of the mostly used application service in day to day life. This concept is very useful and helps in building some better real time apps based on version and generation changes.

So I think we all are now good to go and implement this concept.

The Complete Code of MainPage.xaml looks like this:

<phone:PhoneApplicationPage

        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">

        </Grid>
    </Grid>

    <!--Sample code showing usage of ApplicationBar-->
    <!--<phone:PhoneApplicationPage.ApplicationBar>
        <shell:ApplicationBar IsVisible="True" IsMenuEnabled="True">
            <shell:ApplicationBarIconButton IconUri="/Images/appbar_button1.png" Text="Button 1"/>

        </shell:ApplicationBar>
    </phone:PhoneApplicationPage.ApplicationBar>-->

</phone:PhoneApplicationPage>

The Complete Code of MainPage.xaml.cs looks like this:

using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;

namespace Windows_SMS_Application
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();

        }
        SmsComposeTask objSmsComposeTask = new SmsComposeTask();
        PhoneApplicationService objPhoneService = PhoneApplicationService.Current;

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            if (textBox1.Text == "" || textBox2.Text == "")
            {
                textBlock3.Text = "Message Sent Unsuccessful";
                textBlock3.Foreground = new SolidColorBrush(Colors.Red);
            }
            else
            {
                objSmsComposeTask.To = textBox1.Text;
                objSmsComposeTask.Body = textBox2.Text;
                objSmsComposeTask.Show();
            }

        }
        protected override void OnNavigatedFrom(System.Windows.Navigation.NavigationEventArgs e)
        {
            objPhoneService.State["numbertext"] = textBox1.Text;
            objPhoneService.State["messagetext"] = textBox2.Text;
            base.OnNavigatedFrom(e);
        }
        protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
        {
            object sample;
            if (objPhoneService.State.TryGetValue("numbertext", out sample))
                textBox1.Text = sample as string;
            if (objPhoneService.State.TryGetValue("messagetext", out sample))
                textBox2.Text = sample as string;
            base.OnNavigatedTo(e);
        }

    }
}

The Output of the Application looks like this:

The Output of Sending Application looks like this:

The Output of Nothing Entered Application looks like this:
