+# 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 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 just 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.*
