DependencyProperty.GetMetadata Method (DependencyObject)
Returns the metadata for this dependency property as it exists on the specified object instance.
Assembly: WindowsBase (in WindowsBase.dll)
- Type: System.Windows.DependencyObject
A dependency object that is checked for type, to determine which type-specific version of the dependency property the metadata should come from.
Return ValueType: System.Windows.PropertyMetadata
A property metadata object.
Specifying either the type or an object reference is necessary because the metadata of any given dependency property can vary from the original registration due either to AddOwner or OverrideMetadata calls that can refine the property metadata as it exists on a type.
When you request property metadata based on an instance, you are really just passing the instance so that its type can be evaluated internally. Dependency property metadata does not vary per instance; it is always consistent for any given type-property combination.
