WP7: How to Localize you DatePicker

Create your DatePicker application described in this article or your own application.

Insert in MainPage.xaml.cs

using System.Globalization;
using System.Threading;

Windows Phone supports the display languages you may find here

Next code fragment do all you need (of course you must choose "Culture code" you need):

public MainPage()
{
    CultureInfo newCulture = new CultureInfo("en-GB");
    Thread.CurrentThread.CurrentCulture = newCulture;
    Thread.CurrentThread.CurrentUICulture = newCulture;

    ...
}

But if your language not supported by windows phone?

public MainPage()
{
    CultureInfo newCulture = new CultureInfo("en-GB");

    //change format of DatePicker to you own format
    newCulture.DateTimeFormat.ShortDatePattern = "d/MMM/yyyy";

    //set day names
    newCulture.DateTimeFormat.DayNames = new string[] { "first day", 
                                                        "second day", 
                                                        "third day", 
                                                        "4 day", 
                                                        "5 day", 
                                                        "6 day", 
                                                        "7 day" };

    //set month names
    newCulture.DateTimeFormat.MonthNames = new string[] {"1 month", 
                                                         "2 month", 
                                                         "3 month", 
                                                         "4 month", 
                                                         "5 month", 
                                                         "6 month", 
                                                         "7 month", 
                                                         "8 month", 
                                                         "9 month", 
                                                         "10 month", 
                                                         "11 month", 
                                                         "12 month", 
                                                         ""};

    Thread.CurrentThread.CurrentCulture = newCulture;
    Thread.CurrentThread.CurrentUICulture = newCulture;

    ...
}

WP7 - Create DatePicker control programmatically

If you need use DatePicker in your windows phone application you must create control field in xaml file. Or no...
Let's create DatePicker control programmatically without any code in xaml file.

Install Silverlight Toolkit last version.
Create new "Windows Phone Application" named "DatePickerControlProgrammatically".
Adding new reference to Microsoft.Phone.Controls.Toolkit

Main Menu -> Project -> Add Reference -> Tab ".NET" -> choose Microsoft.Phone.Controls.Toolkit.
If you no find Microsoft.Phone.Controls.Toolkit in ".NET" tab go to "Browse" tab and navigate to this dll in you computer (for me "C:\Program Files\Microsoft SDKs\Windows Phone\v7.0\Toolkit\Sep10\Bin\Microsoft.Phone.Controls.Toolkit.dll").

Create new folder in project "Toolkit.Content" and put inside two images for cancel and check control (you can get them in Silverlight Toolkit project or create you own icons):
Don't forget change "Build Action" property for each image to "Content" from "Resource".

Override DatePicker class with our custom DatePickerCustom class. Create new class "DatePickerCustom.cs":

using System.Windows.Automation.Peers;
using System.Windows.Automation.Provider;
using System.Windows.Controls;
using Microsoft.Phone.Controls;  

namespace DatePickerControlProgrammatically
{
    public class DatePickerCustom : DatePicker
    {
        public void ClickTemplateButton()
        {
            Button btn = (GetTemplateChild("DateTimeButton") as Button);
            ButtonAutomationPeer peer = new ButtonAutomationPeer(btn);
            IInvokeProvider provider = (peer.GetPattern(PatternInterface.Invoke) as IInvokeProvider);

            provider.Invoke();
        }
    }
}

MainPage.xaml.cs - create new DatePickerCustom on Loaded event:

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 DatePickerControlProgrammatically
{
    public partial class MainPage : PhoneApplicationPage
    {
        private DatePickerCustom datePicker;

        // Constructor
        public MainPage()
        {
            InitializeComponent();

            Loaded += new RoutedEventHandler(MainPage_Loaded);
        }

        void MainPage_Loaded(object sender, RoutedEventArgs e)
        {
            // create datePicker programmatically
            if (this.datePicker == null)
            {
                this.datePicker = new DatePickerCustom();
                this.datePicker.IsTabStop = false;
                this.datePicker.MaxHeight = 0;

                this.datePicker.ValueChanged += new EventHandler<DateTimeValueChangedEventArgs>(datePicker_ValueChanged);

                LayoutRoot.Children.Add(this.datePicker);

            }
        }

        void datePicker_ValueChanged(object sender, DateTimeValueChangedEventArgs e)
        {
            // now we may use got value from datePicker
            PageTitle.Text = this.datePicker.ValueString;
        }
    }
}

For test add to MainPage.xaml two buttons - "Get Date" and "Clear Date":

<Button Content="Get Date" Height="72" HorizontalAlignment="Left" 
    Name="button1" VerticalAlignment="Top" 
    Width="160" Click="button1_Click"/>
<Button Content="Clear Date" Height="72" HorizontalAlignment="Right" 
    Name="button2" VerticalAlignment="Top" 
    Width="160" Click="button2_Click"/>

And to MainPage.xaml.cs add control for our buttons:

private void button1_Click(object sender, RoutedEventArgs e)
{
    this.datePicker.ClickTemplateButton();
}

private void button2_Click(object sender, RoutedEventArgs e)
{
    PageTitle.Text = "Page Title";
    clearDatePicker();
}

void clearDatePicker()
{
    this.datePicker.ValueChanged -= new EventHandler<DateTimeValueChangedEventArgs>(datePicker_ValueChanged);

    //this.datePicker.Value = "8/16/2011";
    this.datePicker.Value = null;

    this.datePicker.ValueChanged += new EventHandler<DateTimeValueChangedEventArgs>(datePicker_ValueChanged);
}

WP7 - Download zip file, unzip and save to isolated storage

Create New "Windows Phone Application".
Download "Silverlight SharpZipLib" from http://slsharpziplib.codeplex.com/releases/view/50561.
Unpack "Silverlight SharpZipLib" and copy Bin/Release/SharpZipLib.WindowsPhone7.dll
Create new folder "SharpZip" and past into copied SharpZipLib.WindowsPhone7.dll.
Right click on project and "Add Reference...".
Choose from "Browse" tab SharpZipLib.WindowsPhone7.dll from your project location.
Add to "MainPage.xaml.cs" (probably you need to remove "using System.Windows.Shapes" because conflict System.Windows.Shapes.Path vs System.IO.Path):
```
using System.IO;
using System.IO.IsolatedStorage;
using ICSharpCode.SharpZipLib.Zip;
using ICSharpCode.SharpZipLib.Zip.Compression.Streams;
```

Add code for download file from web:

public MainPage()
{
    InitializeComponent();

    Loaded += new RoutedEventHandler(MainPage_Loaded);
}

void MainPage_Loaded(object sender, RoutedEventArgs e)
{
    System.Uri targetUri = new System.Uri("http://MyDomain/Archive.zip");
    HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(targetUri);
    //create asynchronous tast and declare callback to get data stream
    request.BeginGetResponse(new AsyncCallback(ReadWebRequestCallback), request);
}

And add function "ReadWebRequestCallback" to unzip & save file we got:

private void ReadWebRequestCallback(IAsyncResult callbackResult)
{
    HttpWebRequest myRequest = (HttpWebRequest)callbackResult.AsyncState;
    HttpWebResponse myResponse = (HttpWebResponse)myRequest.EndGetResponse(callbackResult);
    using (StreamReader httpwebStreamReader = new StreamReader(myResponse.GetResponseStream()))
    {
        //open isolated storage to save files
        using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication())
        {
            using (ZipInputStream s = new ZipInputStream(httpwebStreamReader.BaseStream))
            {
                //s.Password = "123456";//if archive is encrypted
                ZipEntry theEntry;
                try
                {
                    while ((theEntry = s.GetNextEntry()) != null)
                    {
                        string directoryName = Path.GetDirectoryName(theEntry.Name);
                        string fileName = Path.GetFileName(theEntry.Name);

                        // create directory
                        if (directoryName.Length > 0)
                        {
                            Directory.CreateDirectory(directoryName);
                        }

                        if (fileName != String.Empty)
                        {
                            //save file to isolated storage
                            using (BinaryWriter streamWriter = 
                                    new BinaryWriter(new IsolatedStorageFileStream(theEntry.Name,
                                        FileMode.OpenOrCreate, FileAccess.Write, FileShare.Write, isoStore)))
                            {

                                int size = 2048;
                                byte[] data = new byte[2048];
                                while (true)
                                {
                                    size = s.Read(data, 0, data.Length);
                                    if (size > 0)
                                    {
                                        streamWriter.Write(data, 0, size);
                                    }
                                    else
                                    {
                                        break;
                                    }
                                }
                            }

                        }
                    }
                }
                catch (ZipException ze)
                {
                    Debug.WriteLine(ze.Message);
                }
            }
        }

    }
}
