Question

I’m adding ellipses in a long for cycle (more than 100 is added), and I want to know a property added in the same for cycle on click event.
inside the for cycle:

 var ellipse = new Ellipse();
 ellipse.myValue=12; // this needs to be editable and working
 ....
 ellipse.MouseDown += ellipseClick;
 canvas2.Children.Add(ellipse);

Here is the listener:

private void ellipseClick(object sender, MouseButtonEventArgs e)
    {
        if(myValue==12) 
        ....
    }

of course it is a bit more complicated, I’d need a pointer or 3 int values for every Ellipse.
I don’t want to go on every Ellipse and check the click position and if it is the same as the sender.
I can’t extend the Ellipse class, because it is sealed, and I can’t rewrite code in the Ellipse class.

Answer 1

You could use the Tag-property, to store additional information.

ellipse.Tag = 12;

I hope that is what you are asking for, but according to your comment on my question, you just want to store information with each ellipse.

You can create a struct or class that contains all the information you want and just set the Tag to that class. It allows you to store about anything you want.
