	Hi! Are there a programatically way to delete nodes and links raising the Node_Deleting and Link_Deleting events? If I do : "diagram1.Items.Remove( diagram1.ActiveItem);" those events are no raised, therefore I can't validate the operation before the elements disappear from the diagram. Those events are raised when I press "Supr" key, so I need do the same than that key do. Cheers.

	Hi! Nope, validation events are raised only for users actions. You could move your validation code to some helper method invoked both from the event handler and from before Remove is called. I hope that helps, Stoyan

	You could add your own command binding for ApplicationCommands.Delete to diagram.CommandBindings. I hope that helps, Stoyan
