# Binding from Code |
||||
|
|
||||
|
Avalonia binding from code works somewhat differently to WPF/UWP. At the low level, Avalonia's |
||||
|
binding system is based on Reactive Extensions' `IObservable` which is then built upon by XAML |
||||
|
bindings (which can also be instantiated in code). |
||||
|
|
||||
|
## Binding to an observable |
||||
|
|
||||
|
You can bind a property to an observable using the `AvaloniaObject.Bind` method: |
||||
|
|
||||
|
```csharp |
||||
|
// We use an Rx Subject here so we can push new values using OnNext |
||||
|
var source = new Subject<string>(); |
||||
|
var textBlock = new TextBlock(); |
||||
|
|
||||
|
// Bind TextBlock.Text to source |
||||
|
textBlock.Bind(TextBlock.TextProperty, source); |
||||
|
|
||||
|
// Set textBlock.Text to "hello" |
||||
|
source.OnNext("hello"); |
||||
|
// Set textBlock.Text to "world!" |
||||
|
source.OnNext("world!"); |
||||
|
``` |
||||
|
|
||||
|
## Binding priorities |
||||
|
|
||||
|
You can also pass a priority to a binding. *Note: Priorities only apply to styled properties: they* |
||||
|
*are ignored for direct properties.* |
||||
|
|
||||
|
The priority is passed using the `BindingPriority` enum, which looks like this: |
||||
|
|
||||
|
```csharp |
||||
|
/// <summary> |
||||
|
/// The priority of a binding. |
||||
|
/// </summary> |
||||
|
public enum BindingPriority |
||||
|
{ |
||||
|
/// <summary> |
||||
|
/// A value that comes from an animation. |
||||
|
/// </summary> |
||||
|
Animation = -1, |
||||
|
|
||||
|
/// <summary> |
||||
|
/// A local value: this is the default. |
||||
|
/// </summary> |
||||
|
LocalValue = 0, |
||||
|
|
||||
|
/// <summary> |
||||
|
/// A triggered style binding. |
||||
|
/// </summary> |
||||
|
/// <remarks> |
||||
|
/// A style trigger is a selector such as .class which overrides a |
||||
|
/// <see cref="TemplatedParent"/> binding. In this way, a basic control can have |
||||
|
/// for example a Background from the templated parent which changes when the |
||||
|
/// control has the :pointerover class. |
||||
|
/// </remarks> |
||||
|
StyleTrigger, |
||||
|
|
||||
|
/// <summary> |
||||
|
/// A binding to a property on the templated parent. |
||||
|
/// </summary> |
||||
|
TemplatedParent, |
||||
|
|
||||
|
/// <summary> |
||||
|
/// A style binding. |
||||
|
/// </summary> |
||||
|
Style, |
||||
|
|
||||
|
/// <summary> |
||||
|
/// The binding is uninitialized. |
||||
|
/// </summary> |
||||
|
Unset = int.MaxValue, |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
Bindings with a priority with a smaller number take precedence over bindings with a higher value |
||||
|
priority, and bindings added more recently take precedence over other bindings with the same |
||||
|
priority. Whenever the binding produces `AvaloniaProperty.UnsetValue` then the next binding in the |
||||
|
priority order is selected. |
||||
|
|
||||
|
## Setting a binding in an object initializer |
||||
|
|
||||
|
It is often useful to set up bindings in object initializers. You can do this using the indexer: |
||||
|
|
||||
|
```csharp |
||||
|
var source = new Subject<string>(); |
||||
|
var textBlock = new TextBlock |
||||
|
{ |
||||
|
Foreground = Brushes.Red, |
||||
|
MaxWidth = 200, |
||||
|
[!TextBlock.TextProperty] = source.ToBinding(), |
||||
|
}; |
||||
|
``` |
||||
|
|
||||
|
Using this method you can also easily bind a property on one control to a property on another: |
||||
|
|
||||
|
```csharp |
||||
|
var textBlock1 = new TextBlock(); |
||||
|
var textBlock2 = new TextBlock |
||||
|
{ |
||||
|
Foreground = Brushes.Red, |
||||
|
MaxWidth = 200, |
||||
|
[!TextBlock.TextProperty] = textBlock1[!TextBlock.TextProperty], |
||||
|
}; |
||||
|
``` |
||||
|
|
||||
|
Of course the indexer can be used outside object initializers too: |
||||
|
|
||||
|
```csharp |
||||
|
textBlock2[!TextBlock.TextProperty] = textBlock1[!TextBlock.TextProperty]; |
||||
|
``` |
||||
|
|
||||
|
# Transforming binding values |
||||
|
|
||||
|
Because we're working with observables, we can easily transform the values we're binding! |
||||
|
|
||||
|
```csharp |
||||
|
var source = new Subject<string>(); |
||||
|
var textBlock = new TextBlock |
||||
|
{ |
||||
|
Foreground = Brushes.Red, |
||||
|
MaxWidth = 200, |
||||
|
[!TextBlock.TextProperty] = source.Select(x => "Hello " + x).ToBinding(), |
||||
|
}; |
||||
|
``` |
||||
|
|
||||
|
# Using XAML bindings from code |
||||
|
|
||||
|
Sometimes when you want the additional features that XAML bindings provide, it's easier to use XAML bindings from code. For example, using only observables you could bind to a property on `DataContext` like this: |
||||
|
|
||||
|
```csharp |
||||
|
var textBlock = new TextBlock(); |
||||
|
var viewModelProperty = textBlock.GetObservable(TextBlock.DataContext) |
||||
|
.OfType<MyViewModel>() |
||||
|
.Select(x => x?.Name); |
||||
|
textBlock.Bind(TextBlock, viewModelProperty); |
||||
|
``` |
||||
|
|
||||
|
However, it might be preferable to use a XAML binding in this case: |
||||
|
|
||||
|
```csharp |
||||
|
var textBlock = new TextBlock |
||||
|
{ |
||||
|
[!TextBlock.TextProperty] = new Binding("Name") |
||||
|
}; |
||||
|
``` |
||||
|
|
||||
|
By using XAML binding objects, you get access to binding to named controls and [all the other features that XAML bindings bring](binding-from.xaml.md): |
||||
|
|
||||
|
```csharp |
||||
|
var textBlock = new TextBlock |
||||
|
{ |
||||
|
[!TextBlock.TextProperty] = new Binding("Text") { ElementName = "other" } |
||||
|
}; |
||||
|
``` |

# Binding from XAML |
||||
|
|
||||
|
Binding from XAML works on the whole the same as in other XAML frameworks: you use the `{Binding}` |
||||
|
markup extension. Avalonia does have some extra syntacic niceties however. Here's an overview of |
||||
|
what you can currently do in Avalonia: |
||||
|
|
||||
|
## Binding to a property on the DataContext |
||||
|
|
||||
|
By default a binding binds to a property on the `DataContext`, e.g.: |
||||
|
|
||||
|
```xml |
||||
|
<!-- Binds to the tb.DataContext.Name property --> |
||||
|
<TextBlock Name="tb" Text="{Binding Name}"/> |
||||
|
<!-- Which is the same as ('Path' is optional) --> |
||||
|
<TextBlock Name="tb" Text="{Binding Path=Name}"/> |
||||
|
``` |
||||
|
|
||||
|
An empty binding binds to DataContext itself |
||||
|
|
||||
|
```xml |
||||
|
<!-- Binds to the tb.DataContext property --> |
||||
|
<TextBlock Name="tb" Text="{Binding}"/> |
||||
|
<!-- Which is the same as --> |
||||
|
<TextBlock Name="tb" Text="{Binding .}"/> |
||||
|
``` |
||||
|
|
||||
|
This usage is identical to WPF/UWP etc. |
||||
|
|
||||
|
## Two way bindings and more |
||||
|
|
||||
|
You can also specify a binding `Mode`: |
||||
|
|
||||
|
```xml |
||||
|
<!-- Bind two-way to the property (although this is actually the default binding mode for |
||||
|
TextBox.Text) so strictly speaking it's unnecessary here) --> |
||||
|
<TextBox Name="tb" Text="{Binding Name, Mode=TwoWay}"/> |
||||
|
``` |
||||
|
|
||||
|
This usage is identical to WPF/UWP etc. |
||||
|
|
||||
|
## Binding to a property on the templated parent |
||||
|
|
||||
|
When you're creating a control template and you want to bind to the templated parent you can use: |
||||
|
|
||||
|
```xml |
||||
|
<TextBlock Name="tb" Text="{TemplateBinding Caption}"/> |
||||
|
<!-- Which is short for --> |
||||
|
<TextBlock Name="tb" Text="{Binding Caption, RelativeSource={RelativeSource TemplatedParent}}"/> |
||||
|
``` |
||||
|
|
||||
|
This usage is identical to WPF/UWP etc. |
||||
|
|
||||
|
## Binding to a named control |
||||
|
|
||||
|
If you want to bind to a property on another (named) control, you can use `ElementName` as in |
||||
|
WPF/UWP: |
||||
|
|
||||
|
```xml |
||||
|
<!-- Binds to the Tag property of a control named "other" --> |
||||
|
<TextBlock Text="{Binding Tag, ElementName=other}"/> |
||||
|
``` |
||||
|
|
||||
|
However Avalonia also introduces a shorthand syntax for this: |
||||
|
|
||||
|
```xml |
||||
|
<TextBlock Text="{Binding #other.Tag}"/> |
||||
|
``` |
||||
|
|
||||
|
## Negating bindings |
||||
|
|
||||
|
You can also negate the value of a binding using the `!` operator: |
||||
|
|
||||
|
```xml |
||||
|
<TextBox IsEnabled="{Binding !HasErrors}"/> |
||||
|
``` |
||||
|
|
||||
|
Here, the `TextBox` will only be enabled when the view model signals that it has no errors. Behind |
||||
|
the scenes, Avalonia tries to convert the incoming value to a boolean, and if it can be converted |
||||
|
it negates the value. If the incoming value cannot be converted to a boolean then no value will be |
||||
|
pushed to the binding target. |
||||
|
|
||||
|
This syntax is specific to Avalonia. |
||||
|
|
||||
|
## Binding to tasks and observables |
||||
|
|
||||
|
You can subscribe to the result of a task or an observable by using the `^` stream binding operator. |
||||
|
|
||||
|
```xml |
||||
|
<!-- If DataContext.Name is an IObservable<string> then this will bind to the length of each |
||||
|
string produced by the observable as each value is produced --> |
||||
|
<TextBlock Text="{Binding Name^.Length}"/> |
||||
|
``` |
||||
|
|
||||
|
This syntax is specific to Avalonia. |
||||
|
|
||||
|
*Note: the stream operator is actually extensible, see |
||||
|
[here](https://github.com/AvaloniaUI/Avalonia/blob/master/src/Markup/Avalonia.Markup/Data/Plugins/IStreamPlugin.cs) |
||||
|
for the interface to implement and [here](https://github.com/AvaloniaUI/Avalonia/blob/master/src/Markup/Avalonia.Markup/Data/ExpressionObserver.cs#L47) |
||||
|
for the registration.* |

Any raw assets you want to be deployed with your application can be placed in |
||||
|
this directory (and child directories) and given a Build Action of "AndroidAsset". |
||||
|
|
||||
|
These files will be deployed with you package and will be accessible using Android's |
||||
|
AssetManager, like this: |
||||
|
|
||||
|
public class ReadAsset : Activity |
||||
|
{ |
||||
|
protected override void OnCreate (Bundle bundle) |
||||
|
{ |

base.OnCreate (bundle); |

|
||||
|
InputStream input = Assets.Open ("my_asset.txt"); |
||||
|
} |
||||
|
} |
||||
|
|
||||
|
Additionally, some Android functions will automatically load asset files: |

|
|

Typeface tf = Typeface.CreateFromAsset (Context.Assets, "fonts/samplefont.ttf"); |

|
Images, layout descriptions, binary blobs and string dictionaries can be included |
||||
|
in your application as resource files. Various Android APIs are designed to |
||||
|
operate on the resource IDs instead of dealing with images, strings or binary blobs |
||||
|
directly. |
||||
|
|
||||
|
For example, a sample Android app that contains a user interface layout (main.axml), |
||||
|
an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png) |
||||
|
would keep its resources in the "Resources" directory of the application: |
||||
|
|
||||
|
Resources/ |
||||
|
drawable/ |
||||
|
icon.png |
||||
|
|
||||
|
layout/ |
||||
|
main.axml |
||||
|
|
||||
|
values/ |
||||
|
strings.xml |
||||
|
|
||||
|
In order to get the build system to recognize Android resources, set the build action to |
||||
|
"AndroidResource". The native Android APIs do not operate directly with filenames, but |
||||
|
instead operate on resource IDs. When you compile an Android application that uses resources, |
||||
|
the build system will package the resources for distribution and generate a class called "R" |
||||
|
(this is an Android convention) that contains the tokens for each one of the resources |
||||
|
included. For example, for the above Resources layout, this is what the R class would expose: |
||||
|
|
||||
|
public class R { |
||||
|
public class drawable { |
||||
|
public const int icon = 0x123; |
||||
|
} |
||||
|
|
||||
|
public class layout { |
||||
|
public const int main = 0x456; |
||||
|
} |
||||
|
|
||||
|
public class strings { |
||||
|
public const int first_string = 0xabc; |
||||
|
public const int second_string = 0xbcd; |
||||
|
} |
||||
|
} |
||||
|
|
||||
|
You would then use R.drawable.icon to reference the drawable/icon.png file, or R.layout.main |
||||
|
to reference the layout/main.axml file, or R.strings.first_string to reference the first |
||||
|
string in the dictionary file values/strings.xml. |
