Remarks

Learn how to offer files for the user to pick from your app in Quickstart: Providing file services through file pickers and in the Windows.Storage.Pickers.Provider namespace reference.

This object is accessed when you implement an event handler for the WinJS.Application.Onactivated or the Windows.UI.WebUI.WebUIApplication.activated events when ActivationKind is fileOpenPicker.

Note  : This class is not agile, which means that you need to consider its threading model and marshaling behavior. For more info, see Threading and Marshaling (C++/CX).

Examples

The File picker sample demonstrates how to respond to a fileOpenPicker activated event.

// File open picker activated event handler
function activated(eventObject) {
    // Identify whether app is launched for fileOpenPicker
    if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.fileOpenPicker) {
        // Perform tasks to prepare your app to display its file picker page

        // Get file picker UI
        fileOpenPickerUI = eventObject.detail.fileOpenPickerUI;

        eventObject.setPromise(WinJS.UI.processAll().then(function () {
            // Navigate to either the first scenario or to the last running scenario
            // before suspension or termination.
            var url = scenarios[0].url;
            return WinJS.Navigation.navigate(url, fileOpenPickerUI);
        }));
    }
}

// Register the activated event handler
WinJS.Application.addEventListener("activated", activated, false);

For JavaScript, eventObject contains a webUIFileOpenPickerActivatedEventArgs object.
