Before reading this article, I highly recommend reading my previous articles:

In this part, I will explain how to write an application and access a TextBox value in Windows Phone.

Let's start to write the application.

Write first Application

Select New project from the File menu and select Windows Phone applicaton. Add three TextBoxes to the grid panel and add one button and two textboxes for entering values and a third TextBox for the result.

MainPage.xaml

<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
<TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
<TextBlock x:Name="PageTitle" Text="1st Application" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
</StackPanel>
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<TextBlock x:Name="lblfirst" Text="Enter 1st Number" Margin="25,38,241,527"></TextBlock>
<TextBlock x:Name="lblsecond" Text="Enter 2nd Number" Margin="25,98,241,467"></TextBlock>
<TextBlock x:Name="lblresult" Text="Result" Margin="25,161,241,404"></TextBlock>
<TextBox x:Name="txtfirst" Margin="225,24,6,508"></TextBox>
<TextBox x:Name="txtsecond" Margin="225,84,6,450"></TextBox>
<TextBox x:Name="txtresult" Margin="225,147,6,381"></TextBox>
<Button x:Name="btnadd" Height="95" Content="Addition" Margin="0,232,0,280" Click="btnadd_Click"></Button>
</Grid>
</Grid

Figure 1

Let's write the code for the button click event. The first and second TextBoxes accept the user input data and the third TextBox shows the addition of the two numbers.

MainPage.xaml.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
namespace WriteFirstApplication
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
}
private void btnadd_Click(object sender, RoutedEventArgs e)
{
int result = Convert.ToInt32(txtfirst.Text)+Convert.ToInt32(txtsecond.Text);
txtresult.Text = result.ToString();
}
}
}

After doing everything run your application.

first application

Figure 2

Now write one more code for showing the result in the messagebox. You can add only one line for the message box.

MessageBox.Show(“YourContent”)

MainPage.xaml.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
namespace WriteFirstApplication
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
}
private void btnadd_Click(object sender, RoutedEventArgs e)
{
int result = Convert.ToInt32(txtfirst.Text)+Convert.ToInt32(txtsecond.Text);
MessageBox.Show("Addition of "+ txtfirst.Text +"&"+ txtsecond.Text +"=" +result.ToString());
}
}
}
