Windows Phone Toolkit How to get full Popup ListPicker? - windows-phone-7

I am wondering how do you make it so the list picker goes to a separate screen when clicked on?
I tried
<toolkit:ListPicker Margin="155,109,179,0" VerticalAlignment="Top" ItemTemplate="{StaticResource PriceTypesTemplate1}" ItemsSource="{Binding PriceTypes}" FullModeItemTemplate="{StaticResource PickerFullModeItemTemplate}"/>
But that crashes the app saying it can't find PickerFullModeItemTemplate

Did you provide a ressource named PickerFullModeItemTemplate ?
Your code specify two separate custom templates for each of the states (ItemTemplate and FullModeItemTemplate). Here is a very basic example.
c#
public class Cities
{
public string Name { get; set; }
public string Country { get; set; }
public string Language { get; set; }
}
List<Cities> source = new List<Cities>();
source.Add(new Cities() { Name = "Madrid", Country = "ES", Language = "Spanish" });
source.Add(new Cities() { Name = "Las Vegas", Country = "US", Language = "English" });
source.Add(new Cities() { Name = "London", Country = "UK", Language = "English" });
source.Add(new Cities() { Name = "Mexico", Country = "MX", Language = "Spanish" });
this.listPicker.ItemsSource = source;
xaml
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<Grid.Resources>
<DataTemplate x:Name="PickerItemTemplate">
<StackPanel Orientation="Horizontal">
<Border Background="LightGreen" Width="34" Height="34">
<TextBlock Text="{Binding Country}" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
<TextBlock Text="{Binding Name}" Margin="12 0 0 0"/>
</StackPanel>
</DataTemplate>
<DataTemplate x:Name="PickerFullModeItemTemplate">
<StackPanel Orientation="Horizontal" Margin="16 21 0 20">
<TextBlock Text="{Binding Name}" Margin="16 0 0 0" FontSize="43" FontFamily="{StaticResource PhoneFontFamilyLight}"/>
<TextBlock Text="language: "/>
<TextBlock Text="{Binding Language}" Foreground="Green"/>
</StackPanel>
</DataTemplate>
</Grid.Resources>
<toolkit:ListPicker ExpansionMode="FullScreenOnly" x:Name="listPicker" ItemTemplate="{StaticResource PickerItemTemplate}" FullModeItemTemplate="{StaticResource PickerFullModeItemTemplate}" Header="Cities" FullModeHeader="Cities" CacheMode="BitmapCache"/>
</Grid>
If you do not want to have custom templates then you can use a simple list of strings with the default ones
<toolkit:ListPicker ExpansionMode="FullScreenOnly" x:Name="listPicker" Header="Header" FullModeHeader="Full mode Header" CacheMode="BitmapCache"/>

How to change pivot header into page number?

I have a pivot control, the items are binded from a list, I want to make the pivot header look like a page number, look like this : (1/20) (2/20) (3/20) .... This is my xaml:
<Grid x:Name="LayoutRoot">
<Grid.Background>
<ImageBrush ImageSource="/Images/PivotBackground.png"/>
</Grid.Background>
<!--Pivot Control-->
<controls:Pivot x:Name="newsPivot" ItemsSource="{Binding LatestArticles}" Margin="0,68,0,0">
<!--Pivot item one-->
<controls:Pivot.HeaderTemplate>
<DataTemplate>
<TextBlock Text="1" FontSize="30" Foreground="White" TextWrapping="Wrap"/>
</DataTemplate>
</controls:Pivot.HeaderTemplate>
<controls:Pivot.ItemTemplate>
<DataTemplate>
<ScrollViewer>
<Grid>
<StackPanel>
<TextBlock Text="{Binding title}" FontSize="30" Foreground="Black" TextWrapping="Wrap"
Grid.Row="1"
Grid.Column="0"
Width="425"
Margin="10,0,0,0"/>
</StackPanel>
<StackPanel>
<Image delay:LowProfileImageLoader.UriSource="{Binding thumbnail, StringFormat='http://digitaledition.philstar.com/newsrepository/newsarticles/thumbs/images/\{0\}'}"
Margin="18,100,0,0"
Grid.Column="0"
Grid.Row="2"
HorizontalAlignment="Left"
Width="150"
Height="175"
Stretch="UniformToFill" />
</StackPanel>
<StackPanel>
<TextBlock Text="{Binding author, StringFormat='By \{0\}'}" TextWrapping="Wrap" FontSize="22"
Grid.Column="1"
Width="220"
Foreground="Gray"
Margin="120,135,0,0"/>
</StackPanel>
<StackPanel>
<TextBlock Text="{Binding dateFormatted}" TextWrapping="Wrap" FontSize="20"
Grid.Column="1"
Width="240"
Foreground="Gray"
Margin="140,210,0,0"/>
</StackPanel>
<StackPanel>
<TextBlock Text="{Binding content}" TextWrapping="Wrap" FontSize="24"
Grid.Column="1"
Width="425"
Foreground="Black"
Margin="10,325,0,0"/>
</StackPanel>
</Grid>
</ScrollViewer>
</DataTemplate>
</controls:Pivot.ItemTemplate>
<!--Pivot item two-->
</controls:Pivot>
</Grid>
Spent hours of searching on google but no solution found. Please someone help me with my project. thanks in advance!
Code behind Xaml:
public NewsPivot()
{
InitializeComponent();
var y = new WebClient();
Observable
.FromEvent<DownloadStringCompletedEventArgs>(y, "DownloadStringCompleted")
.Subscribe(r =>
{
var des =
JsonConvert.DeserializeObject<List<LatestArticles>>(r.EventArgs.Result);
newsPivot.ItemsSource = des.Where(s=> s.category_id == "1");
});
y.DownloadStringAsync(
new Uri("http://sample.json.com/mobile/articles?"));
}
LatestArticle.cs :
public class LatestArticles
{
public string id { get; set; }
public string title { get; set; }
public string thumbnail { get; set; }
public string hits { get; set; }
public string thumbCaption { get; set; }
public string category_id { get; set; }
public string dateFormatted { get; set; }
public string author { get; set; }
}
You would have to Bind the Text of the Header to a property on your Articles object. This propery would be the page index of the article.
<controls:Pivot.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding PageNumber}" FontSize="30" Foreground="White" TextWrapping="Wrap"/>
</DataTemplate>
</controls:Pivot.HeaderTemplate>
You would then need to set the page number of the Article when it is added to the LatestArticles collection.
LatestArticles.Add(article);
article.PageNumber = LatestArticles.Count +1;
Another option is to use a value converter. This option would require you to have access to the LatestArticles somehow.
<controls:Pivot.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding Converter={StaticResource PageNumberConverter}}" FontSize="30" Foreground="White" TextWrapping="Wrap"/>
</DataTemplate>
</controls:Pivot.HeaderTemplate>
The ValueConverter is very simple
public class PageNumberConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
// Assumes that the App.xaml.cs class has a static ViewModel property
return App.ViewModel.LatestArticles.IndexOf(value) + 1;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}

Windows Phone 7 MVVM databinding form

I'm new to Windows Phone development, and currently have a simple form. I'm using the MVVM pattern and MvvmLight to run a command. The "Applicant" entity is always empty, and it looks like the 2 way databinding isn't working. Here is my code, I hope someone can point me in the right direction.

View code behind
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
base.OnNavigatedTo(e);
ApplicantViewModel vm = new ApplicantViewModel();
DataContext = vm;
}
View Model (the view model inherits from ViewModelBase which implements INotifyPropertyChanged)
public class ApplicantViewModel : ViewModelBase
{
public ApplicantViewModel()
{
SaveApplicantCommand = new RelayCommand(SaveApplicant);
Applicant = new Applicant();
}
public ICommand SaveApplicantCommand {get; set;}
void SaveApplicant()
{
if (string.IsNullOrEmpty(Applicant.Forename))
{
MessageBox.Show("Please enter a forename", "Oops...", MessageBoxButton.OK);
return;
}
db.AddObject("Applicants", Applicant);
db.BeginSaveChanges(OnChangesSaved, db);
}
void OnChangesSaved(IAsyncResult result)
{
}
private Applicant _applicant;
public Applicant Applicant
{
get
{
return _applicant;
}
set
{
if (_applicant != value)
{
_applicant = value;
RaisePropertyChanged("Applicant");
}
}
}
}
Whatever is entered into the Forename text box, I always get the error message because Forename is null.
***** UPDATE *********
Here is the Forename property in the model
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Data.Services.Design", "1.0.0")]
public string Forename
{
get
{
return this._Forename;
}
set
{
this.OnForenameChanging(value);
this._Forename = value;
this.OnForenameChanged();
this.OnPropertyChanged("Forename");
}
}
An ApplicantViewModel does not have a Forename property. Only Applicant has. So do the following:
<TextBox Width="350" BorderBrush="Red"
DataContext="{Binding Applicant.Forename, Mode=TwoWay}"/>
do the same with the other text boxes.

Display app setting in a WP7 ListBox control

I have a ListBox control which is binded to a ObservableCollection.
My XAML code:
<ListBox Margin="12,148,12,90" ItemsSource="{Binding FuelRecords}" Name="ListBox1">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="Fuel quantity: {Binding Quantity}" FontSize="20" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I want to display a unit of measure (litre, gallon), after the quantity. The measurement unit is saved using IsolatedStorageSettings in the AppSettings class (VolumeSettingproperty).
End result:
Fuel quantity: 23.45 gallon
public class Fuel
{
public double QuantityGallons { get; set; }
public double Quantity
{
get
{
return QuantityGallons * (AppSettings["VolumeSetting"] == Units.Pounds) ? 1.5 : 1.0;
}
}
public string Units
{
get
{
return (AppSettings["VolumeSetting"] == Units.Pounds) ? "pound" : "gallon";
}
}
}
xaml:
<StackPanel Orientation="Horizontal">
<TextBlock Text="Fuel quantity: " FontSize="20" />
<TextBlock Text="{Binding Quantity}" FontSize="20" />
<TextBlock Text="{Binding Units}" FontSize="20" />
</StackPanel>

Listpicker binding issue WP7

I am having an issue when trying to bind an object I created to a listpicker. I have had success using a listpicker with strings and ints but I am running into issues when trying to use my own class/object.
Here is the XML (I have two listpickers, one works and one doesn't)
<toolkit:ListPicker
x:Name="CountryListPicker"
Margin="0,2,0,10" Width="458"
BorderThickness="3" FullModeHeader="Country"
CacheMode="BitmapCache">
<toolkit:ListPicker.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Border Background="LightBlue" Width="34" Height="34">
<TextBlock Text="{Binding _code}" FontSize="16" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
<TextBlock Text="{Binding _name}" Margin="12 0 0 0"/>
</StackPanel>
</DataTemplate>
</toolkit:ListPicker.ItemTemplate>
<toolkit:ListPicker.FullModeItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0 21 0 20">
<TextBlock Text="{Binding _name}" Margin="16 0 0 0" FontSize="43" FontFamily="{StaticResource PhoneFontFamilyLight}"/>
</StackPanel>
</DataTemplate>
</toolkit:ListPicker.FullModeItemTemplate>
</toolkit:ListPicker>
<toolkit:ListPicker
x:Name="testPicker"
Header="Accent color"
FullModeHeader="ACCENTS"
CacheMode="BitmapCache">
<toolkit:ListPicker.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding}" Margin="12 0 0 0"/>
</StackPanel>
</DataTemplate>
</toolkit:ListPicker.ItemTemplate>
<toolkit:ListPicker.FullModeItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0 21 0 20">
<TextBlock Text="{Binding}"
Margin="16 0 0 0"
FontSize="43"
FontFamily="{StaticResource PhoneFontFamilyLight}"/>
</StackPanel>
</DataTemplate>
</toolkit:ListPicker.FullModeItemTemplate>
</toolkit:ListPicker>`
The first list picker is my new object binding one and the second is binding a string.
Here is the code behind:
ObservableCollection<Country> countries = new ObservableCollection<Country>();
countries.Add(new Country { _code = "US", _name = "United States1"});
countries.Add(new Country { _code = "US", _name = "United States2" });
countries.Add(new Country { _code = "US", _name = "United States3" });
countries.Add(new Country { _code = "US", _name = "United States4" });
countries.Add(new Country { _code = "US", _name = "United States5" });
countries.Add(new Country { _code = "US", _name = "United States6" });
this.CountryListPicker.ItemsSource = new ReadOnlyCollection<Country>(countries);
ObservableCollection<string> _accentColors = new ObservableCollection<string>();
_accentColors.Add("Blue");
_accentColors.Add("Blue2");
_accentColors.Add("Blue3");
_accentColors.Add("Blue4");
_accentColors.Add("Blue5");
_accentColors.Add("Blue6");
_accentColors.Add("Blue7");
this.testPicker.ItemsSource = new ReadOnlyCollection<string>(_accentColors);
The 2nd listpicker is fine and I think this is because it contains strings.
My broken listpicker displays all of the correct data but when I select a listpickeritem, it doesn't select it. The app loads the full listpicker and I click one of the items and when I return back to the main view the selected item isn't reflected in the listpicker.
Anyone have any ideas? Need me to explain anymore?
I figured this one out on my own. I had a Loaded function where the listpicker was initializing. Looks like Loaded gets "loaded" when the listpicker returns from the fullscreen view which in turn resets the selectedIndex. Fix was easy, just move the creation of the lists as well as setting the itemSource from the Loaded function into the constructor.

Windows Phone 7 - Images & Themes in a databound listbox

I have a listbox that I'm doing some databinding. As you can see I have some images associated with the data that I'm displaying... Everything is working great, except that when I change themes I need to change my image to the black images. I can't seem to figure out how to change the images when they are bound like this.
Any ideas?
<ListBox x:Name="lbPharm" ItemsSource="{Binding col}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel x:Name="DataTemplateStackPanel" Orientation="Horizontal">
<TextBlock FontFamily="Segoe WP Semibold" FontWeight="Bold" FontSize="30" VerticalAlignment="Top" Margin="20,10">*</TextBlock>
<StackPanel>
<TextBlock x:Name="ItemText" Text="{Binding name}" FontSize="{StaticResource PhoneFontSizeLarge}"/>
<TextBlock x:Name="ItemNumber" Text="{Binding number}" FontSize="{StaticResource PhoneFontSizeNormal}"/>
</StackPanel>
<Image Source="Images/phone.png" Margin="20,0" x:Name="phone" Visibility="Visible">
<toolkit:GestureService.GestureListener>
<toolkit:GestureListener Tap="GestureListener_Tap_Phone"/>
</toolkit:GestureService.GestureListener>
</Image>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
You should create a binding for the image source instead of setting it explicitly in XAML.
<ListBox x:Name="lbPharm" ItemsSource="{Binding col}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel x:Name="DataTemplateStackPanel" Orientation="Horizontal">
<TextBlock FontFamily="Segoe WP Semibold" FontWeight="Bold" FontSize="30" VerticalAlignment="Top" Margin="20,10">*</TextBlock>
<StackPanel>
<TextBlock x:Name="ItemText" Text="{Binding name}" FontSize="{StaticResource PhoneFontSizeLarge}"/>
<TextBlock x:Name="ItemNumber" Text="{Binding number}" FontSize="{StaticResource PhoneFontSizeNormal}"/>
</StackPanel>
<!-- Image source is bound to a property -->
<Image Source="{Binding ImageSource}" Margin="20,0" x:Name="phone" Visibility="Visible">
<toolkit:GestureService.GestureListener>
<toolkit:GestureListener Tap="GestureListener_Tap_Phone"/>
</toolkit:GestureService.GestureListener>
</Image>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Now, just update the property in your view model as needed, as long as the class containing the property implements INotifyPropertyChanged the new image will show up in your ListBox.
The ImageSource property may have to be a BitmapImage instead of a string. XAML must use a converter to convert your path string when it is used as a literal but I think it doesn't do this if you use a binding. Or you could use your own converter. Either way, construct a BitmapImage as follows:
new BitmapImage( new Uri( "/path/to/image.png", UriKind.Relative ) )
EDIT
Adding an example:
<DataTemplate x:Key="LongListSelectorItemTemplate">
<StackPanel VerticalAlignment="Top"
Orientation="Horizontal">
<toolkit:GestureService.GestureListener>
<toolkit:GestureListener Tap="OnTap" />
</toolkit:GestureService.GestureListener>
<Image Source="{Binding ImageSource}"
MinHeight="32"
MinWidth="32"
MaxHeight="48"
MaxWidth="48" />
<StackPanel>
<TextBlock Text="{Binding Name}"
Style="{StaticResource PhoneTextExtraLargeStyle}"
Margin="12,10,12,0" />
<TextBlock Text="{Binding Parent}"
Foreground="{StaticResource PhoneAccentBrush}"
Style="{StaticResource PhoneTextSubtleStyle}"
Margin="24,0,12,10" />
</StackPanel>
</StackPanel>
</DataTemplate>
Corresponding view model:
public class Item : INotifyPropertyChanged
{
#region Private Members
private string _name = null;
private string _imageSource = null;
private string _parent = null;
#endregion
public string Name
{
get
{
return _name;
}
set
{
if( value != _name ) {
_name = value;
NotifyPropertyChanged( "Name" );
}
}
}
public string Parent
{
get
{
return _parent;
}
set
{
if( value != _parent ) {
_parent = value;
NotifyPropertyChanged( "Parent" );
}
}
}
public string ImageSource
{
get
{
return _imageSource;
}
set
{
if( value != _imageSource ) {
_imageSource = value;
NotifyPropertyChanged( "ImageSource" );
}
}
}
#region INotifyPropertyChanged Members
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged( String propertyName )
{
PropertyChangedEventHandler handler = PropertyChanged;
if( null != handler ) {
handler( this, new PropertyChangedEventArgs( propertyName ) );
}
}
#endregion
}
This is code from a project I'm working on, it is similar to your case except I'm displaying the image with a LongListSelector instead of a ListBox. And it looks like I mislead you earlier about not being able to use a string directly for the image source, I'm doing exactly that and it works. Sorry about that.
