Namespace : DevExpress.Xpf.Editors
Assembly : DevExpress.Xpf.Core.v25.2.dll
NuGet Package : DevExpress.Wpf.Core
public event RoutedEventHandler Checked
Public Event Checked As RoutedEventHandler
The Checked event's data class is RoutedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Handled | Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. |
| OriginalSource | Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. |
| RoutedEvent | Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. |
| Source | Gets or sets a reference to the object that raised the event. |
The event data class exposes the following methods:
| Method | Description |
|---|---|
| InvokeEventHandler(Delegate, Object) | When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. |
| OnSetSource(Object) | When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. |
The Checked event is raised after the editor has been set to the checked state by an end-user or in code by setting the CheckEdit.IsChecked property to true.
The following code snippets (auto-collected from DevExpress Examples) contain references to the Checked event.

The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
