DiagramNodeToolDropped event

 Hi All,
       I'd like to be able to execute some custom code when a toolbox item is dropped onto the diagram surface. I found the DiagramNodeToolDropped event, which seemed to do exactly what I need, but I can't get it working properly. Here's how I'm using it:

XAML:

<ms:DiagramNodeTool Margin="10" Builder="{ms:BuilderType local:SendMessageNodeBuilder}" ToolTip="Send Message" DiagramNodeToolDropped="DiagramNodeTool_DiagramNodeToolDropped">

C#

    private void DiagramNodeTool_DiagramNodeToolDropped(object sender, ToolDroppedEventArgs e)
    {

    }

When I try to run the project however, I get the following error: "Handler type is mismatched". I'm using the latest nightly build of wpf diagrams.
Any thoughts on what I'm doing wrong?

Thanks!

It looks like there's an error in the CLR wrapper event which is causing Visual Studio to generate the wrong signature for the event handler.  Can you try changing ToolDroppedEventArgs to DiagramNodeToolDroppedEventArgs in the handler signature and see if that helps?

 Hi Ivan, Thanks for the reply. It does recognize the DiagramNodeToolDroppedEventArgs class as existing, but if I change the paraemter to that I get this error: No overload for 'DiagramNodeTool_DiagramNodeToolDropped' matches delegate 'System.EventHandler<Mindscape.WpfDiagramming.Foundation.ToolDroppedEventArgs>'

Hmm, I believe this is still the bug at our end.  We can get you a fix in the nightly build, or if you just want to get on then you should be able to bypass the erroneous CLR event handler and write (in the .xaml.cs file):

tool.AddHandler(DiagramNodeTool.DiagramNodeToolDroppedEvent, DiagramNodeTool_DiagramNodeToolDropped);

(You will still need to keep the updated event handler function signature, and to remove the event reference from your XAML.)

 I'll just wait for the fix in the nightly build. Adding the event that way does allow the program to compile, but the event never fires so I suspect something else is wrong.

Thanks for your help.
