Doing drag drop with HandPointers

Question

As first seen on this thread:
http://social.msdn.microsoft.com/Forums/en-US/6b8d6251-c59a-46c7-9da8-b912cb16dfab/kinectregionaddhandpointerhandler?forum=kinectv2sdk
Take a look at http://1drv.ms/VQxR00
I've zipped up a DragDropElement implementation and a DragDropSample page.
You can place those 3 files in ControlsBasics-WPF in the Pages folder. Then add the following to the SampleDataSource -- put it near the KinectPointerPointSample reference in SampleDataSource.cs:
            group1.Items.Add(
                     new SampleDataItem(
                         "Group-1-Item-6",
                         "Drag Drop",
                         string.Empty,
                         SampleDataSource.lightGrayImage,
                         "Shows how to implement a DragDropElement",
                         itemContent,
                         group1,
                         typeof(DragDropSample)));
Would love feedback about this.
Thanks, Rob

Answer 1

This is a nice example of how to move a rectangle around a Canvas in Kinect...
But how can it interact with other objects? In my case ones that have AllowDrop="True"?
For example: If I put your DragDropElement around an Image then shift it up to a Canvas that is subscribed to the Drop event nothing is fired upon letting go.
The mouse equivalent of:
private void ImagePreview_MouseDown(object sender, MouseButtonEventArgs e)
DragDrop.DoDragDrop((DependencyObject)sender, ((Image)sender).Source, DragDropEffects.Copy);
private void Canvas_Drop(object sender, DragEventArgs e)
foreach (var format in e.Data.GetFormats())
ImageSource imageSource = e.Data.GetData(format) as ImageSource;
if (imageSource != null)
// Do something...
