Sets the application link that a contains.

A URI with a scheme that isn't http or https that's handled by the source app. Whenever possible, you should set this property. This URI represents a deep link that takes the user back to the currently displayed content. A source app provides a value for this property, and a target app reads the value. Use this property to indicate the source of the shared content. The scheme of this URI must not be http or https. The app sharing this URI must be capable of being the default handler, although it may not be set as the default handler.

Sets or gets a DataPackage object that contains the content a user wants to share.

Programmatically initiates an exchange of content with other apps.

The class is a static class that you use to initiate sharing operations. To use the class, first call the method. This method returns the object that is specific to the active window. Next, you need to add an event listener for the datarequested event to the object. This event is fired when your app starts a share operation programmatically. The DataTransferManager class includes a method, which you can use to programmatically start a share operation. In general, we recommend against using this method. Users expect to initiate share operations by using the Share charm—when you launch the operation programmatically, you can create an inconsistent user experience. We include the method because there are a few scenarios in which the user might not recognize opportunities to share. A good example is when the user achieves a high score in a game. The class also has a event. Use this event when you want to capture what applications a user selects when sharing content from your app.

Returns the object associated with the current window.

The object associated with the current window.

Programmatically initiates the user interface for sharing content with another app.

Occurs when a share operation starts.

This event is fired when a sharing operation starts. To handle this event, you need to add an event listener to the object for the active window. You can get this object through the method. When handling a datarequested event, the most important property you need to be aware of is its request property. This property contains a object. Your app uses this object to provide the data that the user wants to share with a selected target app.

Occurs when the user chooses a target app in a Share operation.

When the user chooses a target app to share content with, the system fires a TargetApplicationChosen event. The app receiving the event can use this event to record information about the target app for business intelligence. A common use of this event is to record which applications are used to complete different sharing actions, which in turn can help the source app create better experiences for the user.

Contains static properties that return string values. Each string corresponds to a known format ID. Use this class to avoid errors in using string constants to specify data formats.

A read-only property that returns the format ID string value corresponding to the Text format.

A read-only property that returns the format ID string value corresponding to the Uniform Resource Identifier (URI) format.

Contains information about the target app the user chose to share content with. To get this object, you must handle the TargetApplicationChosen event.

Contains the name of the app that the user chose to share content with.

Vibrates the phone.

Phone devices include a vibration controller. Your app can vibrate the phone for up to 5 seconds to notify the user of an important event. Use the vibration feature in moderation. Do not rely on the vibration feature for critical notifications, because the user can disable vibration To test an app that uses the vibration controller effectively, you have to test it on a physical device. The emulator cannot simulate vibration and does not provide any audible or visual feedback that vibration is occurring. An app that is running in the background cannot vibrate the phone. If your code tries to use vibration while the app is running in the background, nothing happens, but no exception is raised. If you want to vibrate the phone while your app is running in the background, you have to implement a toast notification.
