Object Delete Notification

Hi,

I am creating some rectangles dynamically using the code.

Syncfusion.Windows.Forms.Diagram.Rectangle regionRect = new Syncfusion.Windows.Forms.Diagram.Rectangle(10,10,50,50);

this.model1.AppendChild(regionRect);

When the User Selects / Clicks a particular rectangle, how can retrieve the properties of that selected rectangle?

Moreover, I am adding the rectangles to my collection.
When the user deletes the rectangle, how do I know which rectangle is deleted.

All i need to know is whenever the user selects or deletes a rectangle, I need the properties of that selected object. Howe Can I get this?

Version Number: 6.3.0.32

Thanks in advance,
Murali
