RoutedPropertyChangedEventArgs<T> Class
Provides data about a change in value to a dependency property as reported by particular routed events, including the previous and current value of the property that changed.
System.EventArgs
System.Windows.RoutedEventArgs
System.Windows.RoutedPropertyChangedEventArgs<T>
Namespace: System.Windows
Assembly: System.Windows (in System.Windows.dll)
The RoutedPropertyChangedEventArgs<T> type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | RoutedPropertyChangedEventArgs<T> | Initializes a new instance of the RoutedPropertyChangedEventArgs<T> class, with provided old and new values. |
| Name | Description | |
|---|---|---|
![]() ![]() | NewValue | Gets the new value of a property as reported by a property-changed event. |
![]() ![]() | OldValue | Gets the previous value of the property as reported by a property-changed event. |
![]() ![]() | OriginalSource | Gets a reference to the object that raised the event. (Inherited from RoutedEventArgs.) |
| Name | Description | |
|---|---|---|
![]() ![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() ![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
![]() ![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() ![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() ![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
This is a generic class where the class is used for event data of different events. Different routed events can specify the type constraint of the generic to produce a type-specific event data class. Once the class is constrained, the OldValue and NewValue properties also reflect these type constraints. Therefore, you can use a common event data class for different property-changed events without requiring different delegates for each possible property type.
