XamlSetValueEventArgs Class

.NET Framework 4.6 and 4.5

Provides data for callbacks that are invoked when a XamlObjectWriter sets certain values.

Namespace:  System.Windows.Markup
Assembly:  System.Xaml (in System.Xaml.dll)

public class XamlSetValueEventArgs : EventArgs

The XamlSetValueEventArgs type exposes the following members.

Public methodXamlSetValueEventArgsInitializes a new instance of the XamlSetValueEventArgs class.

Public propertyHandledGets or sets a value that determines whether a caller that is using the XamlSetValueEventArgs can use the values without having to call CallBase.
Public propertyMemberGets XAML type system and XAML schema information for the member being set.
Public propertyValueGets the value to provide for the member being set.

Public methodCallBaseWhen overridden in a derived class, provides a way to invoke a SetValue callback as defined on a base class of the current acting type.
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

XamlSetValueEventArgs provides data specifically for callbacks associated with a XamlObjectWriter or its settings. The callbacks use the generic EventHandler<TEventArgs> delegate, with XamlSetValueEventArgs event data constraint.

This event data class is potentially used for set-value callback scenarios that are not specifically markup extensions or type converters acting. There are also two subclasses of XamlSetValueEventArgs for more specific XAML value setting cases, and the specific event data class constrains that event data. XamlSetMarkupExtensionEventArgs is used for the markup extension callback case and XamlSetTypeConverterEventArgs is used for the type converter callback case. An example of a scenario where the set-value operation is not a markup extension or type converter is the DataTrigger scenario in WPF data binding.
