NodeModifying is not fired for multiple selected items (Read 1714 times)

	Hello, I encounter an issue with a NodeModifying event. This event is fired properly when a single node is selected. Even NodeModified works fine. But when multiple nodes are selected NodeModifying event stops to be fired and NodeModified still works. Can you please check if it is a bug? Thanks Jan

	Hi, The diagram raises SelectionModifying event for multiple-selection, try handling that by calling your single-item-modifying code for each selected node. Regards, Slavcho Mindfusion

	Hi, you are right, I can do that, but it is still strange because NodeModified works for both cases single-selection and multi-selection. I would expect if the NodeModifying event is not fired when multi-selection is done, then even NodeModified shouldn't be fired also. Jan

	Hi, Modifying and Modified are raised for different things, former being validation events that let you give feedback to users or cancel the operation altogether. In SelectionModifying you have more context to decide whether modification should be cancelled, which you might not know from a single node in NodeModifying. Anyway we guess it won't hurt raising additional NodeModifying just for their notification aspect, we'll have it in mind for next release. Regards, Slavcho

	Hi, I understand, but in my case, I don't need to know about context because I just need to run a simple code for every node when it is in modifying state. But as I wrote I can do it by calling this code from SelectionModifying event handler method for now. Adding additional raising of NodeModifying event would be fine. Thank you Jan
