XamlSetValueEventArgs Class

.NET Framework 4.6 and 4.5

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

Assembly:  System.Xaml (in System.Xaml.dll)

public class XamlSetValueEventArgs : EventArgs

System_CAPS_pubmethodXamlSetValueEventArgs(XamlMember, Object)

Initializes a new instance of the XamlSetValueEventArgs class.


Gets or sets a value that determines whether a caller that is using the XamlSetValueEventArgs can use the values without having to call CallBase.


Gets XAML type system and XAML schema information for the member being set.


Gets the value to provide for the member being set.


When overridden in a derived class, provides a way to invoke a SetValue callback as defined on a base class of the current acting type.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns 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.
