Assembly: WindowsBase (in WindowsBase.dll)

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 nullNothingnullptra null reference (Nothing in Visual Basic), then the property is not a dependency property. If the method returns a valid DependencyPropertyDescriptor , then the property is a dependency property.
