In Microsoft Outlook 2016 for Mac, you are repeatedly prompted for.Lastly, the problem of Outlook on Windows being different from Outlook on Mac will get worse. What if Microsoft replaces the Windows version with a similarly rebuilt product? Perhaps it will but the difficulty is that Outlook is baked into the Windows ecosystem and forms part of workflows, some automated with COM technology, that will break if Microsoft replaces it. Custom add-ins, VBA projects, ancient APIs that remain for legacy reasons, all mean this will be a tricky application to replace.

The source application can put different formats in the DataPackage, which will make it compatible with more targets, as shown in Figure 3. The application must configure the DataPackage by filling its content and indicating which operations are supported. The XAML framework handles gesture recognition and fires the DragStarting event to indicate the start of a drag operation. This can be done in the markup or in the codebehind. Emulator mac gameboy colorDuring a drag-and-drop operation, the following events can be raised on a target: DragEnter, DragOver, DragLeave and Drop. DragStarting and DropCompleted are events related to the UIElement’s CanDrag property.Implementing a Drop Target Any UIElement can be a drop target provided its AllowDrop property is set to true. That is, if a ListView has its CanDragItems property set to true, only DragItemsStarting and DragItemsCompleted are raised. Programmatically canceling after the DragStarting event is possible through the IAsyncOperation interface, but might be disturbing for the user.Note that although both the ListView drag and drop and the UIElement drag and drop are implemented on the same system services and are fully compatible, they don’t raise the same events on the source side. Once StartDragAsync is called, the rest of the drag and drop operation follows the same pattern as if CanDrag=True had been used, including the DragStarting event.Once the user has released the pointer, the drag-and-drop operation is complete and the source is notified through the DropCompleted event, which contains the DataPackageOperation returned by the target on which the user released the pointer, or DataPackageOperation.None if the pointer was released on a target that doesn’t accept the data or if Cancel was pressed: private void DropGrid_DropCompleted(UIElement sender, DropCompletedEventArgs args)If (args.DropResult = DataPackageOperation.Move)// Move means that we should clear our own imageStartDragAsync returns an IAsyncOperation the source application can handle the end of the operation either by waiting on the IAsyncOperation or by handling the DropCompleted event. Note that this method expects a pointer identifier and, therefore, you can’t start a drag-and-drop operation with non-standard devices, such as a Kinect sensor. This is an asynchronous operation and requires the target application to take a deferral and later complete it (this pattern is detailed later in this article).Once the target has determined if it can process the data, it must set the AcceptedOperation property of the DragEventArgs instance to allow the system to provide the right feedback to the user.Note that if the application returns DataTransferOperation.None—or an operation not accepted by the source—from an event handler, drop won’t take place even if the user releases the pointer over the target the DragLeave event will be raised instead.The application can handle either DragEnter or DragOver the AcceptedOperation returned by DragEnter is kept if DragOver isn’t handled. In some cases, such as with files, the application might have to check the type of the available files before accepting or ignoring the DataPackage. When handling a drag-and-drop event, the target application should first inspect the content of the DataPackage through the DataView property of the event argument in most cases, checking for the presence of a data type is enough and it can be done synchronously. Custom margins for single page word 2016 macIn the sample application, each photo placeholder checks for images in the DataPackage and routes the event to the parent grid only if no image is available, which allows the grid to accept Text even if it’s physically dropped on a placeholder (see Figure 4).Figure 4 Handling DragEnter and Inspecting DataPackage private async void DropGrid_DragEnter(object sender, DragEventArgs e)Bool forceMove = ((e.Modifiers & DragDropModifiers.Shift) =If (e.DataView.Contains(StandardDataFormats.Bitmap))E.AcceptedOperation = (forceMove ? DataPackageOperation.Move :E.DragUIOverride.Caption = "Drop the image to show it in this area" Else if (e.DataView.Contains(StandardDataFormats.StorageItems))// Notify XAML that the end of DropGrid_Enter does// not mean that we have finished to handle the eventE.AcceptedOperation = DataPackageOperation.None Var items = await e.DataView. However, in the case of nested targets, it’s necessary to return the correct value from DragOver in case a parent target might override it (setting Handled to true prevents the event from bubbling up to the parent).
