Question

I’m making a custom button (Winforms Control Library) and have the code below so that all mouseenter will be added to all controls in my button. When I run it, it causes a stack overflow exception. I have the same code with Click instead of MouseEnter and it works fine. Here is the code:

public new event EventHandler MouseEnter {
    add
    {
        this.MouseEnter += value;
        foreach (Control i in Controls)
        {
            i.MouseEnter += value;
        }
    }
    remove
    {
        this.MouseEnter -= value;
        foreach (Control i in Controls)
        {
            i.MouseEnter -= value;
        }
    }
}

here is the click code:

public new event EventHandler Click {
    add {
        this.Click += value;
        foreach (Control i in Controls) {
            i.Click += value;
        }
    }
    remove {
        this.Click -= value;
        foreach (Control i in Controls) {
            i.Click -= value;
        }
    }
}

I ended up replaceing this.Click with base.Click.

    public new event EventHandler Click {
        add {
            base.Click += value;
            foreach (Control i in Controls) {
                i.Click += value;
            }
        }
        remove {
            base.Click -= value;
            foreach (Control i in Controls) {
                i.Click -= value;
            }
        }
    }
