How to add a Click event to an Ellipse in code behind?

Question

To add a click event to a Button in C# code behind, I can do this

Button btn = new Button;
btn.Click += btn_Click;

What if I have an Ellipse, which does not contain a Click?

Ellipse e = new Ellipse;
e.??? += e_Click;

One way to do that is make button an ellipse and attatch .Click Event handler.

<Button>
    <Button.Template>
        <ControlTemplate>
            <Ellipse .../>
        </ControlTemplate>
    </Button.Template>
</Button>

Maybe the MouseUp event will serve your purpose. Try

Ellipse ellipse = new Ellipse();
ellipse.MouseUp += ellipse_MouseUp;

private void ellipse_MouseUp(object sender, MouseButtonEventArgs e)
{
   ...
}

MouseUp != Click, just saying. – H.B. Apr 06 '11 at 03:44
@H.B. agreed but since there is no Click, you'll have to pick one of MouseUp, MouseDown, MouseLeftButtonDown, MouseLeftButtonUp, MouseRightButtonDown, MouseRightButtonUp. – Bala R Apr 06 '11 at 03:51
I posed a question about this actually, you can create a click from those events or use behaviours, it's all a bit messy though, the cleanest thing would be to wrap it in a button but who knows if this would be an option here.
