I have converted an Angular project into a hybrid app following this guide:
https://medium.com/#christof.thalmann/convert-angular-project-to-android-apk-in-10-steps-c49e2fddd29
For Android I did not run into many issues and the app is working as expected on that platform.
On IOS I ran into multiple difficulties. First of all in order contents display I needed to change the Angular LocationStrategy to HashLocation as describe in this SO topic:
Why Angular Router 8 router ...
Although I now do get content to render I still have trouble getting the dynamic content (i.e. the content requiring a call to a web server before rendering) to render properly.
My app has got a classic NavBar to switch from one component to another. If I activate one component by clicking on a Nav Button the static content gets rendered ok. However, the dynamic content is not there. I can verify this by looking at the source code: The holding the dynamic content is empty. If I click on the same Nav Button again the dynamic content is added. I get the same effect on an iPhone simulator and on a real device.
This is the html of one of the components

My suspicion is that it has something to do with the WKWebView of Apple. As it is the first time I am actually developing something in the Apple World I have the feeling that some Apple security feature is blocking something.
Update:
I did 2 additional checks:
In order to check if any styling stuff was causing the issue I removed all the stylings. However, same problem.
In order to check if the dynamic data is actually fetched from the server when initiating the component I added a console.log() to print the data after it is fetched. It is fetched correctly but the screen does not update to display the data.
Update 2:
Updating from Angular 9 to Angular 10 also did not solve the problem.
After a lot of trial and error and searching I found the solution.
I found a hint here:
https://github.com/angular/angular/issues/7381[1]
For a reason I fo not fully understand yet the app seems to switch zones during the async call to the server. Therefore the UI change mechanism is not triggered and the screen is not updated.
By wrapping the changes of variables into NgZone.run()the screen is updated correctly.
The updated .ts file
import { Component, OnInit, NgZone } from '#angular/core';
// ...
constructor(private service: SummaryService, private authService: AuthService, private zone: NgZone) { }
// ...
getMonthScore(): void {
this.service.getScore('month').subscribe(score => {
this.zone.run(() => {
this.monthScore = score;
this.createMonthGraph();
console.log('GOT MONTH SCORE');
console.log(score);
});
})
}
This is required only when building an iOS app with Cordova. When building an Android app or using the browser does not seem necessary.
I am creating UWP application.I have few LinearGradientBrushes, where the color is set directly in the LinearGradientBrush reference as GradientStops. However, I want to have a predefined set of colors defined in the resource distionary that I can use a a reference for each GradientStop, so that changing the color scheme for the application is a matter of changing the values of the SolidColorBrushes:
<!--Resource Dictionary -->
<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Default">
<SolidColorBrush x:Key="stop1" Color="#FF5A5A5A"/>
<SolidColorBrush x:Key="stop2" Color="#FF222222"/>
</ResourceDictionary>
<ResourceDictionary x:Key="Dark">
<SolidColorBrush x:Key="stop1" Color="Black"/>
<SolidColorBrush x:Key="stop2" Color="White"/>
</ResourceDictionary>
<ResourceDictionary x:Key="HighContrast">
<SolidColorBrush x:Key="stop1" Color="Black"/>
<SolidColorBrush x:Key="stop2" Color="White"/>
</ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>
<!-- control Template-->
<LinearGradientBrush x:Key="gradient">
<GradientStop Color="{Binding Source={Themeresource stop1},Path=Color}" Offset="0"/>
<GradientStop Color="{Binding Source={Themeresource stop2},Path=Color}" Offset="1"/>
</LinearGradientBrush>
Its Giving error that nam/key stop1 is not Found
The problem is stop1 is static resource but not Themeresource . So, we need edit binding source as StaticResource.
<LinearGradientBrush x:Key="gradient">
<GradientStop Color="{Binding Source={StaticResource stop1},Path=Color}" Offset="0"/>
<GradientStop Color="{Binding Source={StaticResource stop2},Path=Color}" Offset="1"/>
</LinearGradientBrush>
Update
For the testing, if we place above in ResourceDictionary, it will work.
<Page.Resources>
<ResourceDictionary>
<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Default">
<SolidColorBrush x:Key="stop1" Color="#FF5A5A5A"/>
<SolidColorBrush x:Key="stop2" Color="#FF222222"/>
</ResourceDictionary>
<ResourceDictionary x:Key="Dark">
<SolidColorBrush x:Key="stop1" Color="Black"/>
<SolidColorBrush x:Key="stop2" Color="White"/>
</ResourceDictionary>
<ResourceDictionary x:Key="HighContrast">
<SolidColorBrush x:Key="stop1" Color="Black"/>
<SolidColorBrush x:Key="stop2" Color="White"/>
</ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>
<!-- control Template-->
<LinearGradientBrush x:Key="gradient">
<GradientStop Color="{Binding Source={ThemeResource stop1},Path=Color}" Offset="0"/>
<GradientStop Color="{Binding Source={ThemeResource stop2},Path=Color}" Offset="1"/>
</LinearGradientBrush>
</ResourceDictionary>
</Page.Resources>
The above problem can be solved by using binding
public LinearGradientBrush GradientBrush
{
get { return _GradientBrush; }
set
{
_GradientBrush = value;
RaisePropertyChanged("GradientBrush");
}
}
GradientBrush = GetGradientBrush();
public static LinearGradientBrush GetGradientBrush()
{
var grColor1 = ((SolidColorBrush)Application.Current.Resources["stop1"]).Color;
var grColor2 = ((SolidColorBrush)Application.Current.Resources["stop2"]).Color;
LinearGradientBrush lgBrush = new LinearGradientBrush();
lgBrush.GradientStops.Add(new GradientStop() { Color = grColor1, Offset = 0.1 });
lgBrush.GradientStops.Add(new GradientStop() { Color = grColor2, Offset = 0.9 });
lgBrush.StartPoint = new Point(0, 1);
lgBrush.EndPoint = new Point(1, 0);
return lgBrush;
}
<Grid Background="{Binding GradientBrush}" >
When I launch the Windows Phone Settings app, what is presented is a pivot control with a bunch of items on each page. For example, the first item is:
THEME
blue
What is the standard way of creating these items? I want them to have the same font style and look. Is there any control to represent the item above?
Thanks!
It is a ListBox control and a DataTemplate for eacht item. The template defines two TextBox controls, one for the 'title' and one for a 'description/value'. You can set the style for each TextBox.
Edit: here's an example code
<ListBox x:Name="YourListBox" Margin="0" ItemsSource="{Binding YourItems}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding ItemTitle}" TextWrapping="Wrap" Style="{StaticResource PhoneTextTitle2Style}"/>
<TextBlock Text="{Binding ItemValue}" TextWrapping="Wrap" Style="{StaticResource PhoneTextSubtleStyle}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
After playing with this for 2 hours pixel by pixel and using a paint program to compare screenshots with the real thing side by side (there's gotta be a better way!), I found the following solution.
Here is the settings page replicated exactly. I've created a custom user control so that adding an item to xaml is as easy as this:
<MyApp:SettingsItem Label="theme" Sub="blue"/>
Here's the code:
SettingsItem.xaml.cs
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
namespace MyApp
{
// This custom control class is to show a standard item in a settings page.
public partial class SettingsItem : UserControl
{
private const string TAG = "SettingsItem";
public SettingsItem()
{
// Required to initialize variables
InitializeComponent();
}
public static readonly DependencyProperty LabelProperty =
DependencyProperty.Register(
"Label",
typeof(string),
typeof(SettingsItem),
new PropertyMetadata(new PropertyChangedCallback
(OnLabelChanged)));
public string Label
{
get
{
return (string)GetValue(LabelProperty);
}
set
{
SetValue(LabelProperty, value);
}
}
private static void OnLabelChanged(DependencyObject d,
DependencyPropertyChangedEventArgs e)
{
SettingsItem item = (SettingsItem)d;
string newValue = (string)e.NewValue;
item.m_label.Text = newValue.ToLower();
}
public static readonly DependencyProperty SubProperty =
DependencyProperty.Register(
"Sub",
typeof(string),
typeof(SettingsItem),
new PropertyMetadata(new PropertyChangedCallback
(OnSubChanged)));
public string Sub
{
get
{
return (string)GetValue(SubProperty);
}
set
{
SetValue(SubProperty, value);
}
}
private static void OnSubChanged(DependencyObject d,
DependencyPropertyChangedEventArgs e)
{
SettingsItem item = (SettingsItem)d;
string newValue = (string)e.NewValue;
item.m_sub.Text = newValue;
}
}
}
SettingsItem.xaml

My suggestion:
<Button>
<Button.Template>
<ControlTemplate>
<StackPanel>
<TextBlock Text="Label" Style="{StaticResource PhoneTextExtraLargeStyle}" Margin="0 18 0 0"/>
<TextBlock Text="Sub" Style="{StaticResource PhoneTextSubtleStyle}" Margin="0 -6 0 0"/>
</StackPanel>
</ControlTemplate>
</Button.Template>
I would like to create a button control that has a Path element as its content--an IconButton if you will.
This button should fulfill two conditions:
1. The Path element's stroke and fill colors should be available for manipulation by the VisualStateManager.
2. The Path element's data string (which defines it's shape) can be set in code or in XAML, so that I can create several such buttons without creating a new custom control for each.
The only way I can see to do it would involve no XAML whatsoever. That is, setting all the visual states and animations in the code behind, plus generating the Geometry objects point by point (and not being able to use the convenient Data string property on the Path element).
Is there a simpler way to do this?
EDIT
So one of the limitations I'm running into is that Silverlight does not support the mini-language for path expressions in PathGeometry, only in Path. I've got some detailed geometry going on in some of these icons, and I really don't want to take the convenient strings I generated with an Illustrator plug-in (pretty sure it was this one) and make them into separate line segments and curves.
Nice one Chris. If you want to store the paths as resources, you can modify things a bit like so:
First change the dependency property to a Path type:
/// <summary>
/// Button that contains an icon, where the icon is drawn from a path.
/// </summary>
public class IconButton : Button
{
/// <summary>
/// The path data that draws the icon.
/// </summary>
public static readonly DependencyProperty IconPathProperty =
DependencyProperty.Register("IconPath", typeof(Path), typeof(IconButton), new PropertyMetadata(default(Path)));
/// <summary>
/// Depencendy property backer.
/// </summary>
public Path IconPath
{
get { return (Path)GetValue(IconPathProperty); }
set { SetValue(IconPathProperty, value); }
}
}
Next, here's the IconButton control template.
<!-- Icon Button Control Template -->
<ControlTemplate x:Key="IconButtonControlTemplate" TargetType="{x:Type usercontrols:IconButton}">
<Grid x:Name="Grid">
<Border SnapsToDevicePixels="True" x:Name="Border" CornerRadius="1" BorderThickness="1" BorderBrush="{StaticResource ButtonBorderBrush}">
<Path x:Name="Icon" Height="16" Width="16" Stretch="Fill"
Data="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=IconPath.Data}"
UseLayoutRounding="False" Grid.Column="1" VerticalAlignment="Center" Margin="0">
<Path.Fill>
<SolidColorBrush x:Name="IconColor" Color="{Binding Color, Source={StaticResource ButtonIconBrush}}" />
</Path.Fill>
</Path>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter Property="BorderBrush" Value="{StaticResource ButtonBorderBrush}" TargetName="Border"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">

<Trigger Property="IsPressed" Value="true">
<Setter Property="Background" Value="{StaticResource ButtonBackgroundPressedBrush}" TargetName="Border"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Fill" Value="{StaticResource DisabledIconBrush}" TargetName="Icon"/>
<Setter Property="Background" Value="{StaticResource ButtonBackgroundDisabledBrush}" TargetName="Border"/>
<Setter Property="BorderBrush" Value="{StaticResource ButtonBorderDisabledBrush}" TargetName="Border"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
... and here's the IconButton style that uses this template, and adds a few defaults:
<!-- Icon Button Style -->
<Style TargetType="{x:Type usercontrols:IconButton}">
<Setter Property="FocusVisualStyle" Value="{DynamicResource SimpleButtonFocusVisual}"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="VerticalAlignment" Value="Top"/>
<Setter Property="Height" Value="26"/>
<Setter Property="Width" Value="26"/>
<Setter Property="Margin" Value="5"/>
<Setter Property="Content" Value="Button"/>
<Setter Property="Template" Value="{StaticResource IconButtonControlTemplate}"/>
</Style>
Now you can go ahead and create icons and save them in your resource file:
<!-- Undo Icon -->
<Path x:Key="UndoIcon" Stretch="Fill" Data="F1 M 87.7743,80.7396L 87.5215,75.9539L 89.8692,74.2202C 89.9775,75.0329 90.0859,76.586 90.0859,76.5318C 92.9302,73.7417 97.5369,72.9755 100.208,76.2158C 102.019,78.413 102.258,81.2543 99.7657,83.9361C 97.2735,86.6179 92.6142,90.1124 92.6142,90.1124L 90.3748,87.6744L 97.3096,81.769C 97.3096,81.769 99.1516,79.9992 97.8514,78.3558C 96.2374,76.316 94.384,77.2542 92.1447,78.8795C 92.1176,78.9608 93.3998,79.1143 94.3118,79.2768L 92.4336,81.4439L 87.7743,80.7396 Z "/>
<!-- Filter Icon -->
<Path x:Key="FilterIcon" Stretch="Fill" Data="F1 M 6,16L 10,16L 10.0208,10L 16,3L 16,2.86102e-006L 0,9.53674e-007L 0,3L 6,10L 6,16 Z "/>
And finally, create buttons:
<usercontrols:IconButton IconPath="{StaticResource UndoIcon}"></usercontrols:IconButton>
The Path Data property is simply a Geometry. When you say "several such buttons" one assumes that there are a finite number of such buttons which vary with Icon.
Store each "Icon" as a PathGeomerty in a ResourceDictionaryand have that ResourceDictionary referenced as a merged dictionary in the app.xaml.
Now you can simply assign the geomerty into the Path shap Data property.
For the second part of the problem above, here's a kludge which works pretty well for storing string Path data as resources and accessing them from code.
For the first part of the problem, I just created all the animations in code, apply them on mouse events, got rid of the XAML page altogether.
This ship may have long since sailed, but I needed something very similar and was able to roll my own by inheriting from Button:
public class PathButton : Button
{
public static readonly DependencyProperty PathDataProperty =
DependencyProperty.Register("PathData", typeof(Geometry), typeof(PathButton), new PropertyMetadata(default(Geometry)));
public Geometry PathData
{
get { return (Geometry) GetValue(PathDataProperty); }
set { SetValue(PathDataProperty, value); }
}
}
