Drag and drop directions

DragAndDropTrigger and DragAndDropDirection

Since 1.8.2, you can now choose if you want to begin the drag and drop with a Pan gesture or a LongPress.

• DragAndDropTrigger="Pan"
• DragAndDropTrigger="LongTap"

You can also restrict the drag movement to a given direction:

• For the horizontal layout: DragAndDropDirection = HorizontalOnly
• For the vertical layout: DragAndDropDirection = VerticalOnly

It will give a better more precise drag experience, more precise.

Fixes:

• #27: DragAndDropInfo provides incorrect information for moved item
• #26: ItemsSource does not notice changes to underlying ObservableCollection

EnableDragAndDrop at runtime with custom animations !

NEW

• EnableDragAndDrop is now a bindable property so drag and drop can be enabled and disabled at runtime
• You can specify an animation for the drag and drop mode with the DragAndDropEnabledAnimationAsync property
• You can decide to start the drag without long press on iOS thanks to the iOS specific property iOSDragAndDropOnPanGesture to true

Example

            HorizontalListView.DragAndDropEnabledAnimationAsync = async (viewCell, token) =>
            {
                while (!token.IsCancellationRequested)
                {
                    await viewCell.View.RotateTo(8);
                    await viewCell.View.RotateTo(-8);
                }

                await viewCell.View.RotateTo(0);
            };

Reveal animations and DragAndDropInfo

Version 1.8 breaking change

Namespace changed from Sharpnado.Presentation.Forms.HorizontalListView to Sharpnado.HorizontalListView.

HorizontalListView, like MaterialFrame, Tabs and Shadows, now uses the same xml namespace: http://sharpnado.com.

Because of how works xaml compilation, you need to add code in your App.xaml.cs referencing the sharpnado assembly:

public App()
{
    InitializeComponent();

    Sharpnado.HorizontalListView.Initializer.Initialize(true, false);
    ...
}

Reveal animations

Contributor: original idea from @jmmortega.

You can set custom animations on cells that will be triggered when a cell appears for the first time.

Properties for reveal animations

public Func<ViewCell, Task> PreRevealAnimationAsync { get; set; }

public Func<ViewCell, Task> RevealAnimationAsync { get; set; }

public Func<ViewCell, Task> PostRevealAnimationAsync { get; set; }

see docs for example.

DragAndDropInfo

The DragAndDropStartCommand and DragAndDropEndedCommand commands will now pass as argument a DragAndDropInfo object:

public class DragAndDropInfo
{
    public int To { get; }

    public int From { get; }

    public object Content { get; }
}

Contributor: Implemented by @jmmortega.
