Hi JVM,
Thanks for using Syncfusion products.
We suggest you to use Node.Contains(PointF pt) method to achieve your requirement. Here is the code snippet for your reference. [C#] diagram1.MouseUp += new MouseEventHandler(diagram1_MouseUp); void diagram1_MouseUp(object sender, MouseEventArgs e) { PointF curPt = diagram1.Controller.ConvertToModelCoordinates(e.Location); Node node = diagram1.Controller.GetNodeAtPoint(curPt); if (node != null) { if(node.ContainsPoint(curPt)){ MessageBox.Show("Point inside!"); } } }
