Remarks
This class is primarily used by designer applications. These applications may need to report the dependency property characteristics through property windows or other tools used for editing property values.
In order to check a specific property to determine whether it has DependencyPropertyDescriptor available to serve as a PropertyDescriptor, call either DependencyPropertyDescriptor.FromProperty(PropertyDescriptor), or DependencyPropertyDescriptor.FromName. If either method returns null, then the property is not a dependency property. If the method returns a valid DependencyPropertyDescriptor , then the property is a dependency property.
Properties
| Name | Description |
|---|---|
| Attributes |
Gets the collection of attributes for this member. |

| DependencyProperty |
Returns the dependency property identifier. |
| Description |
Gets the description of the member, as specified in the DescriptionAttribute. |
| DesignerCoerceValueCallback |
Gets or sets a callback that designers use to modify the effective value of a dependency property before the dependency property value is stored in the dependency property engine. |
| DesignTimeOnly |
Gets whether this member should be set only at design time, as specified in the DesignOnlyAttribute. |
| DisplayName |
Gets the name that can be displayed in a window, such as a Properties window. |
| IsAttached |
