How to Enable Pan Tool for Diagram Area and Move Tool for Node

In the WF Diagram Control, you can enable the pan tool for the diagram area and the move tool for the node simultaneously by using the NodeMouseEnter and NodeMouseLeave events. We have provided a sample to achieve this requirement.

In this code snippet, we have enabled the SelectTool for the node region using the Node Enter event and PanTool for the diagram page area using the Node Leave event.

// Where diagram is the instance of the Diagram control.

this.diagram.EventSink.NodeMouseEnter += EventSink_NodeMouseEnter;
this.diagram.EventSink.NodeMouseLeave += EventSink_NodeMouseLeave;

private void EventSink_NodeMouseLeave(NodeMouseEventArgs evtArgs)
{
   this.diagram.Controller.ActivateTool("PanTool");
}

private void EventSink_NodeMouseEnter(NodeMouseEventArgs evtArgs)
{
   this.diagram.Controller.ActivateTool("SelectTool");
}
