Using Listpicker in Windows Phone 7

Introduction

ListPicker is a new control in the Silverlight Toolkit for Windows Phone. It is for user's to choose another item like Combobox but ListPicker has more features than a Combobox. When you have little item about 1->4 it'll show data as a Combobox and if more item Listpicker will show data as a ListBox.

In this article I will talk about Listpicker in Windows Phone.

Fundamental

First, you must install Silverlight tool for Windows Phone . you can download it here http://silverlight.codeplex.com/releases/view/71550

Now we're creating Windows Phone Application Project.

Listpicker in Windows Phone

Next, we right click on References -> choose Add Refrences -> choose Microsoft.Phone.Controls.Toolkit :

Then we go to MainPage.xaml and built a sample User Interface but after that we declare

xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"

To use Control.

Now we add some Control to MainPage, they're TextBlock,TextBox and ListPicker:
To Use ListPicker we must Define ItemTemplate and FullModeItemTemplate :

<phone:PhoneApplicationPage.Resources>

<DataTemplate x:Name="lpkItemTemplate">

<TextBlock Text="{Binding Country}" />

</DataTemplate>

<DataTemplate x:Name="lpkFullItemTemplate">

<TextBlock Text="{Binding Country}" />

</DataTemplate>

</phone:PhoneApplicationPage.Resources>

Full XAML Code :

<phone:PhoneApplicationPage

x:Class="ListPickerDemo.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"

xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"

FontFamily="{StaticResource PhoneFontFamilyNormal}"

FontSize="{StaticResource PhoneFontSizeNormal}"

Foreground="{StaticResource PhoneForegroundBrush}"

SupportedOrientations="Portrait" Orientation="Portrait"

shell:SystemTray.IsVisible="True">

<phone:PhoneApplicationPage.Resources>

</DataTemplate>

</DataTemplate>

</phone:PhoneApplicationPage.Resources>

<Grid.RowDefinitions>

</Grid.RowDefinitions>

</StackPanel>

<Grid.RowDefinitions>

</Grid.RowDefinitions>

<toolkit:ListPicker FullModeItemTemplate="{Binding lpkFullItemTemplate}"

Grid.Row="5" ItemTemplate="{Binding lpkItemTemplate}"

x:Name="lpkCountry"/>

</Grid>

</phone:PhoneApplicationPage>

And Now we go to MainPage.xaml.cs and create a Array String as a sample Data, and add is for ListPicker ItemSource Properties:

C# Code :

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 ListPickerDemo

{

public partial class MainPage : PhoneApplicationPage

{

String[] Country = { "Viet Nam","Japan",

"China","USA",

"Poland","Brazil",

"Singapore","Philipin","Malaysia"};

public MainPage()

{

InitializeComponent();

this.lpkCountry.ItemsSource = Country;

}

private void btnSubmit_Click(object sender, RoutedEventArgs e)

{

String _Content = String.Format("Name: {0} \nAges: {1}\nCountry: {2}",

txtName.Text,txtAge.Text,lpkCountry.SelectedItem);

MessageBox.Show(_Content);

}

}

Now We Run Apps to view Resuilt :

When you have a little Country
And More Contry (FullModeItemTamplate will run):
And when I Submit :
