Telerik RadTextBox in Windows Phone 7

Introduction

 

Today, in this article let’s play around with another interesting concepts of Telerik RadControls.

 

Question: What is RadTextbox?

 

In simple terms “The RadTextBox control extends the standard TextBox and provides additional functionality like header and watermark. It also has two buttons: Clear Button and Action Button“.

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

Step 1: The complete code of MainPage.xaml looks like this:

<phone:PhoneApplicationPagex:Class=”RadTextBoxApplication.MainPage”xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation”xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”xmlns:phone=”clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone”xmlns:shell=”clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone”xmlns:d=”http://schemas.microsoft.com/expression/blend/2008″xmlns:mc=”http://schemas.openxmlformats.org/markup-compatibility/2006″mc:Ignorable=”d” d:DesignWidth=”480″d:DesignHeight=”768″FontFamily=&#8221;{StaticResource PhoneFontFamilyNormal}”FontSize=”{StaticResource PhoneFontSizeNormal}”Foreground=”{StaticResource PhoneForegroundBrush}”SupportedOrientations=”Portrait” Orientation=”Portrait”shell:SystemTray.IsVisible=”True” xmlns:telerikPrimitives=”clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Primitives”Loaded=”MainPage1_Loaded”>

<!–LayoutRoot is the root grid where all page content is placed–>

<Grid x:Name=”LayoutRoot” Background=”Transparent”>

<Grid.RowDefinitions>

<RowDefinition Height=”Auto”/>

<RowDefinition Height=”*”/>

</Grid.RowDefinitions>

<!–TitlePanel contains the name of the application and page title–>

<StackPanel x:Name=”TitlePanel” Grid.Row=”0″ Margin=”12,17,0,28″>

<TextBlock x:Name=”ApplicationTitle” Text=”RadTextBox-Application”Style=”{StaticResource PhoneTextNormalStyle}”/>

<TextBlock x:Name=”PageTitle” Text=”Windows 7 Phone” Margin=”9,-7,0,0″Style=”{StaticResource PhoneTextTitle1Style}”/>

</StackPanel>

<!–ContentPanel – place additional content here–>

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

<telerikPrimitives:RadTextBox HorizontalAlignment=”Left” Margin=”77,20,0,478″Width=”311″ Name=”radTxtBox1″ Header=”Please Enter First Number:” FontFamily=”Verdana”FontSize=”22″ ActionButtonVisibility=”Visible”  />

<telerikPrimitives:RadTextBox Height=”118″ HorizontalAlignment=”Left”Margin=”63,135,0,0″   VerticalAlignment=”Top” Width=”340″ Name=”radTxtBox2″ Header=”Please Enter Second Number:” FontFamily=”Verdana” FontSize=”22″ ActionButtonVisibility=”Visible”  />

<Button Content=”Addition” Height=”72″ HorizontalAlignment=”Left”Margin=”122,272,0,0″ VerticalAlignment=”Top” Width=”238″ Click=”Button1_Click”FontFamily=”Verdana” FontSize=”22″/>

<Button Content=”Substraction” Height=”72″ HorizontalAlignment=”Left”Margin=”122,350,0,0″ VerticalAlignment=”Top” Width=”238″ Click=”Button2_Click”FontFamily=”Verdana” FontSize=”22″/>

<Button Content=”Multiplication” Height=”72″ HorizontalAlignment=”Left”Margin=”122,428,0,0″ VerticalAlignment=”Top” Width=”238″ Click=”Button3_Click”FontFamily=”Verdana” FontSize=”22″/>

<Button Content=”Division” Height=”72″ HorizontalAlignment=”Left”Margin=”122,506,0,0″ VerticalAlignment=”Top” Width=”238″ Click=”Button4_Click”FontFamily=”Verdana” FontSize=”22″/>

</Grid>

</Grid>

</phone:PhoneApplicationPage>

Step 2: The complete code of Arthmetic.cs looks like this:

namespace RadTextBoxApplication

{

public class Arthmetic

{

public double Add(double a, double b)

{

return a + b;

}

public double Sub(double a, double b)

{

return a – b;

}

public double Mul(double a, double b)

{

return a * b;

}

public double Div(double a, double b)

{

return a / b;

}

}

}

Step 3: The complete code of MainPage.xaml.cs looks like this:


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;

using Telerik.Windows.Controls;namespace RadTextBoxApplication

{

public partial class MainPage : PhoneApplicationPage

{

// Constructorpublic MainPage()

{

InitializeComponent();

}

public void MainPage1_Loaded(object sender, RoutedEventArgs e)

{

radTxtBox1.Focus();

}

public void Button1_Click(object sender, RoutedEventArgs e)

{

if

(string.IsNullOrEmpty(radTxtBox1.Text) || string.IsNullOrEmpty(radTxtBox2.Text))

{

RadMessageBox.Show(“Please Enter Some Values”, MessageBoxButtons.OKCancel,null,null,false,false,HorizontalAlignment.Center, VerticalAlignment.Center);

}

else

{

double add = _objArthmetic.Add(double.Parse(radTxtBox1.Text),double.Parse(radTxtBox2.Text));

RadMessageBox.Show(“Addition Result is: ” + Convert.ToString(add), MessageBoxButtons.OKCancel,”RadTextBox-Application”, null, false, false, HorizontalAlignment.Center,VerticalAlignment.Center, null);

radTxtBox1.Text = string.Empty;radTxtBox2.Text = string.Empty;

}

}

public void Button2_Click(object sender, RoutedEventArgs e)

{

if (string.IsNullOrEmpty(radTxtBox1.Text) || string.IsNullOrEmpty(radTxtBox2.Text))

{

RadMessageBox.Show(“Please Enter Some Values”, MessageBoxButtons.OKCancel, null, null,false, false, HorizontalAlignment.Center, VerticalAlignment.Center);

}

else

{

double sub = _objArthmetic.Sub(double.Parse(radTxtBox1.Text),double.Parse(radTxtBox2.Text));

RadMessageBox.Show(“Substraction Result is: ” + Convert.ToString(sub), MessageBoxButtons.OKCancel,”RadTextBox-Application”, null, false, false, HorizontalAlignment.Center,VerticalAlignment.Center, null);

radTxtBox1.Text = string.Empty;radTxtBox2.Text = string.Empty;

}

}

public void Button3_Click(object sender, RoutedEventArgs e)

{

if (string.IsNullOrEmpty(radTxtBox1.Text) || string.IsNullOrEmpty(radTxtBox2.Text))

{

RadMessageBox.Show(“Please Enter Some Values”, MessageBoxButtons.OKCancel, null, null,false, false, HorizontalAlignment.Center, VerticalAlignment.Center);

}

else

{

double mul = _objArthmetic.Mul(double.Parse(radTxtBox1.Text),double.Parse(radTxtBox2.Text));

RadMessageBox.Show(“Multiplication Result is: ” + Convert.ToString(mul), MessageBoxButtons.OKCancel,”RadTextBox-Application”, null, false, false, HorizontalAlignment.Center,VerticalAlignment.Center, null);

radTxtBox1.Text = string.Empty;radTxtBox2.Text = string.Empty;

}

}

public void Button4_Click(object sender, RoutedEventArgs e)

{

if (string.IsNullOrEmpty(radTxtBox1.Text) || string.IsNullOrEmpty(radTxtBox2.Text))

{

RadMessageBox.Show(“Please Enter Some Values”, MessageBoxButtons.OKCancel, null, null,false, false, HorizontalAlignment.Center, VerticalAlignment.Center);

}

else

{

double div = _objArthmetic.Div(double.Parse(radTxtBox1.Text), double.Parse(radTxtBox2.Text));

RadMessageBox.Show(“Division Result is: ” + Convert.ToString(div), MessageBoxButtons.OKCancel,”RadTextBox-Application”, null, false, false, HorizontalAlignment.Center,VerticalAlignment.Center, null);

radTxtBox1.Text = string.Empty;radTxtBox2.Text = string.Empty;

}

}

#region Instance Variablesprivate readonly Arthmetic _objArthmetic = new Arthmetic();

#endregion

}

}


Step 4: The output of the application looks like this:

 Step 5: The output of the nothing entered application looks like this:

 

Ouput2.png

Step 6: The output of the addition operation application looks like this:

Ouput3.png

 Step 7: The output of the multiplication operation application looks like this:

 Ouput4.png
