How to handle form events in C#

[menashay]

Hello,

I am absolute beginner in C# so pardon me if the following question is
too easy.

I have a form with a one button. When I click the button I want to
display a message that reads "Button was clicked"
However, I do not want to handle the click event from that form,
instead I want to "transfer" that event to a "controller " class that
shows that message.

The ides is this:
Have a class (call it "controller ")
Controller opens the form
When I click the button the controller is "notified" by the form that
the button was clicked
The controller displays the message "Button was clicked"

Now, how do I accomplish this?

Thank you, Richard

Any chance of a small code example?

Of what? One downside of my rambling is that I offered a number of design
possibilities. You haven't narrowed the question down much from my broad
offering. :)

That said, I would probably go with the "static method in controller class
returning the form" design, if it were me. That might look something like
this:

class Program
{
static void Main()
{
// ... VS-supplied initialization
Application.Run (Controller.For mStartup());
}
}

class Form1 : Form
{
// this would be your usual Form-derived class.

// I've assumed that you've simply made the button
// instance public for the purpose of subscribing
// to its events.
}

class Controller
{
public static Form FormStartup()
{
Controller controller;
Form1 form1;

controller = new Controller();
form1 = new Form1();
form1.button1.C lick += controller.Clic kHandler;
return form1;
}

private void ClickHandler(ob ject sender, EventArgs e)
{
// do whatever in response to click event here
}
}

Hope that helps,
Pete
