node move event

[Administrator]

Which event is fired when we move a node in the diagram?
I tried to use PinPointChanging and PinPointChanged but they did not work.

((DocumentEventSink)model1.EventSink).PinPointChanged += new PinPointChangedEventHandler(MainForm_PinPointChanged);

void MainForm_PinPointChanged(PinPointChangedEventArgs evtArgs)
{
MessageBox.Show("PinpointChanging event is fired" + "" + "Node name: " + evtArgs.NodeAffected.Name.ToString());
}

what could be the problem and is there any other way to detect if any node is moved?

I found the reason. if the editstyle of the diagram is disabled, pinpointchanging will not be fired. rotation change, size change etc. all events work but pinpointchanging and pinpointchanged don't.

Hi lyle,

The pinpointChanged and PinPointChanging event fires whenever a node is moved.

The attached file demonstrates the same.

Let me know if you shall need any further clarifications in this regard.

Happy Coding!

I work alone and would like to know if it is necessary to install any specific components on the client?
