Attached Dependency.Properties. Listen to dependency property changes.How to clear a local value.When you begin to develop appliations with WPF, you will soon stumble across Dependency.Properties. They look quite similar to normal.NET properties, but the concept behind is much more complex and powerful.The main difference is, that the value of a normal.NET property is read directly from a private member in your class, whereas the value of a Dependency.Property is resolved dynamically when calling the Get.Value method that is inherited from Dependency.Object. When you set a value of a dependency property it is not stored in a field of your object, but in a dictionary of keys and values provided by the base class Dependency.Object. The key of an entry is the name of the property and the value is the value you want to set.The advantages of dependency properties are.Reduced memory footprint.Its a huge dissipation to store a field for each property when you think that over 9.UI control typically stay at its initial values.Dependency properties solve these problems by only store modified properties in the instance.The default values are stored once within the dependency property.Value inheritance.When you access a dependency property the value is resolved by using a value resolution strategy.If no local value is set, the dependency property navigates up the logical tree until it finds a value.When you set the Font.Size on the root element it applies to all textblocks below except you override the value.Change notification.Dependency properties have a built in change notification mechanism.By registering a callback in the property metadata you get notified, when the value of the property has been changed.This is also used by the databinding.Every time you access a dependency property, it internally resolves the value by following the precedence from high to low.It checks if a local value is available, if not if a custom style trigger is active.At last the default value is always available.Each WPF control registers a set of Dependency.Properties to the static Dependency.Property class. Each of them consists of a key that must be unique per type and a metadata that contain callbacks and a default value.All types that want to use Dependency.Properties must derive from Dependency.Object. This baseclass defines a key, value dictionary that contains local values of dependency properties.The key of an entry is the key defined with the dependency property.When you access a dependency property over its.NET property wrapper, it internally calls Get.ValueDependency. Property to access the value.This method resolves the value by using a value resolution strategy that is explained in detail below.If a local value is available, it reads it directly from the dictionary.If no value is set if goes up the logical tree and searches for an inherited value.If no value is found it takes the default value defined in the property metadata.This sequence is a bit simplified, but it shows the main concept.To create a Dependency.Property, add a static field of type Depdency.Property to your type and call Dependency.Property. Register to create an instance of a dependency property.The name of the Dependendy.Property must always end with.Property. This is a naming convention in WPF.To make it accessable as a normal.NET property you need to add a property wrapper.This wrapper does nothing else than internally getting and setting the value by using the Get.Value and Set. Value Methods inherited from Dependency.Object and passing the Dependency.Property as key. Important Do not add any logic to these properties, because they are only called when you set the property from code.If you set the property from XAML the Set.Value method is called directly.If you are using Visual Studio, you can type propdp and hit 2x tab to create a dependency property.Dependency Propertypublicstaticreadonly Dependency.Property Current.Time.

Put some update logic here.Coerce Value Callback.The coerce callback allows you to adjust the value if its outside the boundaries without throwing an exception.A good example is a progress bar with a Value set below the Minimum or above the Maximum.In this case we can coerce the value within the allowed boundaries.In the following example we limit the time to be in the past.On.

Time. Propertyobject datareturn data is Date.Time. Some dependency property of WPF controls are readonly.They are often used to report the state of a control, like the Is.Mouse. Over property.Is does not make sense to provide a setter for this value.Maybe you ask yourself, why not just use a normal.NET property One important reason is that you cannot set triggers on normal.NET propeties. Creating a read only property is similar to creating a regular Dependency.Property. Instead of calling Dependency.Property. Register you call Dependency.Property. Register.Readonly. This returns you a Dependency.Property. Key. This key should be stored in a private or protected static readonly field of your class.The key gives you access to set the value from within your class and use it like a normal dependency property.Second thing to do is registering a public dependency property that is assigned to Dependency.Property.

Key, value.Attached properties are a special kind of Dependency.Properties. They allow you to attach a value to an object that does not know anything about this value.A good example for this concept are layout panels.Each layout panel needs different data to align its child elements.The Canvas needs Top and Left, The Dock.Panel needs Dock, etc.Since you can write your own layout panel, the list is infinite.So you see, its not possible to have all those properties on all WPF controls.The solution are attached properties.They are defined by the control that needs the data from another control in a specific context.For example an element that is aligned by a parent layout panel.To set the value of an attached property, add an attribute in XAML with a prefix of the element that provides the attached property.To set the the Canvas.
