Prevent diagram from nodes/links deletion

Hi,

I just thought that there could be diagram's property like "AllowDelete" which could prevent nodes/links from deletion.

Setting e.Cancel=true; in diagram's LinkDeleting/NodeDeleting events is ok, but i think the global flag for diagram items would be nice too  Cheesy

Hi,

You could add a do-nothing binding for the Delete command:

diagram.CommandBindings.Add(new CommandBinding(
     ApplicationCommands.Delete, (x, e) => {}));

This should override the builtin binding to Delete.

I hope that helps,
Stoyan
