1 min read

WPF Diagram (SfDiagram) provides some interactions (Resize, Rotate and Drag) support on Node. The NodeChangedEvent is to notify operation performing on Node with InteractionState as arguments. InteractionState argument is to notify the State of operation (Dragging, Rotating, Resizing, Dragged, Rotated, and Resized) performed on Node using NodeChangedEvent. Please refer to the below code example to achieve this.

C#

//Event to notify the state of operation performed on Node. (diagram.Info as IGraphInfo).NodeChangedEvent += diagram_NodeChangedEvent;
void diagram_NodeChangedEvent(object sender, ChangeEventArgs<object, NodeChangedEventArgs> args)
{  //argument to notify the state of operation performed on Node in NodeChangedEvent.  var InteractionState = args.NewValue.InteractionState;  if (InteractionState == NodeChangedInteractionState.Dragging)  {    //Dragging in Progress   }  if(InteractionState == NodeChangedInteractionState.Dragged)  {    //Dragging Completed   }       }
