PropertyMetadata Constructor (Object)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Initializes a new instance of the PropertyMetadata class, using a property default value.
Assembly: System.Windows (in System.Windows.dll)
'Declaration Public Sub New ( _ defaultValue As Object _ )
public PropertyMetadata( Object defaultValue )
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.
