Coordenates X Y in a textnode

[Blanca Calderon]

Hi,

I need to know, when I move a textnode with a keyboard or a mouse event, its coordenates X and Y. Its so important for me to know the correct coordenates because I save them in an .xml document that I use for configurate a display in a PLC.

I used an event :

void EventSink_NodeDoubleClick(NodeMouseEventArgs evtArgs)

Node node = evtArgs.Node;

 int valorX = (int)node.PinPoint.X - (int)node.PinPointOffset.Width;

 int valorY = (int)node.PinPoint.Y - (int)node.PinPointOffset.Height;

But if I try to get the coordenates in a diagram1_mousedown:

private void diagram1_MouseDown(object sender, MouseEventArgs e)

(Node)this.diagram1.Controller.GetNodeUnderMouse(new Point(e.X, e.Y))

int valorX = (int)node.PinPoint.X - (int)node.PinPointOffset.Width;

 int valorY = (int)node.PinPoint.Y - (int)node.PinPointOffset.Height;

I don't get the same values!! Could you help me??

Hi Blanca, 

Thanks for contacting Syncfusion support. 

We have created a simple sample to achieve your requirement. We suggest you to use Diagram.Model.EventSink’s “PinpointChanging/PinpointChanged” events and Node’s “BoundingRectangle” property to get the node’s coordinates value while performing the drag/drop operation using mouse/keyboard. Please refer to the below sample and code example. 

Code example: 

[C#] 

diagram1.Model.EventSink.PinPointChanged += new PinPointChangedEventHandler(EventSink_PinPointChanged); 

diagram1.Model.EventSink.PinPointChanging += new PinPointChangingEventHandler(EventSink_PinPointChanging); 

void EventSink_PinPointChanging(PinPointChangingEventArgs evtArgs) 

{ 

Node node = evtArgs.NodeAffected as Node; 

float x = node.BoundingRectangle.X; 

float y = node.BoundingRectangle.Y;             

} 

 

void EventSink_PinPointChanged(PinPointChangedEventArgs evtArgs) 

{ 

Node node = evtArgs.NodeAffected as Node; 

float x = node.BoundingRectangle.X; 

float y = node.BoundingRectangle.Y; 

MessageBox.Show("X Value : " + x.ToString() + "\n" + "Y Value : " + y.ToString(), "Nodes Coordinates", MessageBoxButtons.OK); 

}
