Edit: I Simplified the question because even the most basic application, is doing the same thing
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" AllowDrop="True" >
<Canvas DragEnter="Grid_DragEnter" Drop="Grid_Drop" AllowDrop="True" Name="C1">
<Image Height="42" HorizontalAlignment="Left" Margin="27,28,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="42" Source="/WpfApplication1;component/Images/BackgroundMan.PNG" MouseDown="image1_MouseDown" AllowDrop="False" Canvas.Left="-15" Canvas.Top="-16" />
</Canvas>
</Window>
namespace WpfApplication1
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void image1_MouseDown(object sender, MouseButtonEventArgs e)
{
//added a breakpoint it does fire
//C1 is the name of the canvas
DragDrop.DoDragDrop(C1, sender, DragDropEffects.Move);
}
private void Grid_DragEnter(object sender, DragEventArgs e)
{
//added a breakPoint it never fires
e.Effects = DragDropEffects.Move;
}
private void Grid_Drop(object sender, DragEventArgs e)
{
//added a breakPoint it never fires
image1.Margin = new Thickness(e.GetPosition(this).X, e.GetPosition(this).Y, 0, 0);
}
}
}
neither the DragEnter or the Drop events fire
Edit: I added a Window_Drop event, and this is what is accepting the Drop Event, Anyidea why this is, and how do I get the Canvas to accept it. And should I even care, I can work with that I think.

The events will fire if you set a Background
brush.
<Canvas Name="C1" AllowDrop="True"
DragEnter="Grid_DragEnter" Drop="Grid_Drop"
Background="Transparent">

It's not entirely clear to me what you want to do, but setting AllowDrop to true on the image should cause your Grid_DragEnter event to fire if you click and drag on the image.
