DataType Delete Event handlers

I'm trying to hook into the delete event for a datatype to perform a check before a user can delete a document containing that datatype.

Below is the code I am playing with:

public EventDataType()
        {

            DataTypeDefinition.BeforeDelete += new EventHandler<umbraco.cms.businesslogic.DeleteEventArgs>(DataTypeDefinition_BeforeDelete);
            DataTypeDefinition.AfterDelete += new EventHandler<DeleteEventArgs>(DataTypeDefinition_AfterDelete);
            DataTypeDefinition.BeforeSave += new EventHandler<SaveEventArgs>(DataTypeDefinition_BeforeSave);
        }

        void DataTypeDefinition_BeforeDelete(object sender, DeleteEventArgs e)
        {
            throw new NotImplementedException();
        }

        void DataTypeDefinition_AfterDelete(object sender, DeleteEventArgs e)
        {
            throw new NotImplementedException();
        }

        void DataTypeDefinition_BeforeSave(object sender, SaveEventArgs e)
        {
            throw new NotImplementedException();
        }

On saving the NotImplementedException is thrown as expected but when I delete nothing happens suggesting that the event is never fired?

I'm having a similar problem with events not firing on delete.

I'm using the latest version: umbraco v 4.7.1.1 (Assembly version: 1.0.4393.24044)

None of these events are firing for me:
```
Document.BeforeDelete
Document.AfterDelete
CMSNode.BeforeDelete
CMSNode.AfterDelete
```
The following events are firing fine:
```
Document.New
Document.AfterPublish
Document.AfterUnPublish
```
When I delete a node, the AfterUnPublish event does fire, but the isTrashed property of the document is always false regardless of whether it is being deleted or not. So the question is, how do I run code when a node in the site is deleted?

Thanks,

David

Hi all,

Turns out that when you delete a node in the CMS, the Document.AfterUnPublish event fires, followed by the Document.BeforeMoveToTrash and Document.AfterMoveToTrash. That solved my problem (at last!).

Cheers,

David
