|TextChangedEventArgs(RoutedEvent, UndoAction)||Initializes a new instance of the class, using the specified event ID and undo action.|
|TextChangedEventArgs(RoutedEvent, UndoAction, ICollection<TextChange>)||Initializes a new instance of the class, using the specified event ID, undo action, and text changes.|
|Changes||Gets a collection of objects that contains information about the changes that occurred.|
|Handled||Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. (Inherited from RoutedEventArgs.)|
|OriginalSource||Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. (Inherited from RoutedEventArgs.)|
|RoutedEvent||Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. (Inherited from RoutedEventArgs.)|
|Source||Gets or sets a reference to the object that raised the event. (Inherited from RoutedEventArgs.)|
|UndoAction||Gets how the undo stack is caused or affected by this text change|
|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 it 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.)|
|InvokeEventHandler||Performs the proper type casting to call the type-safe TextChangedEventHandler delegate for the TextChanged event. (Overrides RoutedEventArgs::InvokeEventHandler(Delegate, Object).)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|OnSetSource||When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. (Inherited from RoutedEventArgs.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The following example displays the number of times the text in a TextBox changes. Below is the XAML code for the example.
<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="SDKSample.DetectChangedTextExample" Title="DetectChangedText"> <StackPanel> <TextBox Name="tbCountingChanges" TextChanged="textChangedEventHandler" TextWrapping="Wrap"> Here is the initial text in the textbox. Each time the contents of this box is changed, a change counter will be incremented and displayed in the TextBox below. Note that the TextChanged event is called when the TextBox control is initially populated with text, so the changes counter starts of at 1. </TextBox> <TextBox Name="tbCounterText">0</TextBox> </StackPanel> </Page>
Below is the code behind for the example.
