'DeclarationPublic Event PointerCanceled As EventHandler(Of PointerEventArgs)
public event EventHandler<PointerEventArgs> PointerCanceled
The event handler receives an argument of type PointerEventArgs containing data related to this event. The following PointerEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| DeviceType | Gets the PointerDeviceType for the pointer device. |
| Handled | Gets or sets a value that marks the routed event as handled. Setting to true prevents most handlers along the event route from handling the same event again. (Inherited from C1.Win.TouchToolKit.TouchRoutedEventArgs) |
| ID | Gets the system-generated identifier for this pointer reference. |
| IsInContact | Gets a value that determines whether the pointer device was in contact with a sensor or digitizer at the time that the event was reported. |
| IsInRange | Gets a value that determines whether the pointer device was in detection range of a sensor or digitizer at the time that the event was reported. |
| OriginalSource | Gets a reference to the object that raised the event. (Inherited from C1.Win.TouchToolKit.TouchRoutedEventArgs) |
| Position | Gets the x- and y- control coordinates of the touch input at completed position. |
| Properties | Gets extended information about the input pointer. |
| TargetControl | Gets the target control which attached to the C1TouchEventProvider. (Inherited from C1.Win.TouchToolKit.TouchRoutedEventArgs) |
Note PointerCanceled might fire instead of PointerReleased. Don't rely on PointerPressed and PointerReleased events always occurring in pairs. To function properly, your app must listen for and handle all events that represent likely conclusions to the Press action, and that includes PointerCanceled. Some of the reasons why you might get a PointerCanceled occurrence are:
- User actions that change the relationship of the display area, such as changing resolution or monitor settings
- Input interactions such as a stylus touching the same surface as a previous touch action
This event is a routed event. If you do not want parent control receive this event, set PointerEventArgs.Handled
The following code example shows how to use this event.
This code example is part of a larger example provided for the PointerPressed event.
