Question

I am trying to see a reason to use a delegate, and from what I know, a delegate basically what’s for an event.

The event I would have would be in Windows Forms. I have a panel that starts not visible, but when it becomes visible everything in the background becomes disabled (a popup).

I could have it so that whatever makes the panel visible will also cause everything to become disabled, as I usually do. But could I set up a delegate or an event, so whenever that panel is visible, it calls a method that disables everything?

I just can’t figure how to work that out with a delegate.

Answer 1

How about:

panel.VisibleChanged += (sender, args) =>
{
    if (panel.Visible) // Just become visible
    {
        // Disable everything else
    }
};
