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.
Assembly: System.Windows (in System.Windows.dll)
Thetype exposes the following members.
|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.
