Initializes a new instance of the PropertyMetadata class, using a provided property default value and property changed callback reference.
(in System.Windows.dll)
Visual Basic (Declaration)
Public Sub New ( _
defaultValue As Object, _
propertyChangedCallback As PropertyChangedCallback _
)
Dim defaultValue As Object
Dim propertyChangedCallback As PropertyChangedCallback
Dim instance As New PropertyMetadata(defaultValue, _
propertyChangedCallback)
public PropertyMetadata(
Object defaultValue,
PropertyChangedCallback propertyChangedCallback
)
The defaultValue for the PropertyMetadata specified as typeMetadata must be able to be typed as the type parameter, when you call Register or RegisterAttached to register a dependency property. A mismatch of types will not be noted at the time of registration, and will instead produce a run-time exception in type initialization for an instance of the owning type.
Because of the function of the Silverlight property system, the apparent value of a property (even if not locally set) is not always the default value as registered with a property's metadata. For details, see Dependency Property Value Precedence.
Do not use the value UnsetValue as the default value for a custom dependency property. UnsetValue is reserved for use as a sentinel value that participates in dependency property precedence determination.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
