FrameworkPropertyMetadata.Inherits Property

Gets or sets a value that indicates whether the value of the dependency property is inheritable.

Namespace: System.Windows
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public bool Inherits { get; set; }
/** @property */
public boolean get_Inherits ()

/** @property */
public void set_Inherits (boolean value)

public function get Inherits () : boolean

public function set Inherits (value : boolean)

 Members of this class are either not typically used in XAML, or cannot be used in XAML. 

Property Value

true if the property value is inheritable; otherwise, false. The default is false.

Exception typeCondition

InvalidOperationException

The metadata has already been applied to a dependency property operation, so that metadata is sealed and properties of the metadata cannot be set.

Property value inheritance is a feature of the WPF property system at the WPF framework level, whereby certain dependency properties can be locally set on an element at or near the root of a XAML element tree and then have their value inherited by all elements within the logical tree of child elements that also possess that property. Property value inheritance is not enabled by default, and enabling it does have some performance implications. For details, see Property Value Inheritance.

Properties on derived classes of PropertyMetadata are typically defined in the object model as read-write. This is so they can be adjusted after initialization of the instance. However, after the metadata is consumed as part of a call to Register, AddOwner, or OverrideMetadata, the property system will seal that metadata instance and properties that convey the specifics of the metadata are now considered immutable. Attempting to set this property after IsSealed is true on this metadata instance will raise an exception.

The following example obtains the default metadata from various dependency property fields, queries the value of various FrameworkPropertyMetadata properties on it, and uses the information to populate a table to implement a "metadata browser".

    pm = dp.GetMetadata(dp.OwnerType);

...

    FrameworkPropertyMetadata fpm = pm as FrameworkPropertyMetadata;
    if (fpm!=null) {
        AffectsArrange.Text = (fpm.AffectsArrange) ? "Yes" : "No";
        AffectsMeasure.Text = (fpm.AffectsMeasure) ? "Yes" : "No";
        AffectsRender.Text = (fpm.AffectsRender) ? "Yes" : "No";
        Inherits.Text = (fpm.Inherits) ? "Yes" : "No";
        IsDataBindingAllowed.Text = (fpm.IsDataBindingAllowed) ? "Yes" : "No";
        BindsTwoWayByDefault.Text = (fpm.BindsTwoWayByDefault) ? "Yes" : "No";
    }
