Use events.

Declare an event in your UserControl, for instance:

public event EventHandler SaveClicked;

then on save click, raise the event:

if (this.SaveClicked != null)
{
    this.SaveClicked(this, EventArgs.Empty);
}

and finally attach a handler in the main form to your event:

...
YourUserControl ctrl = new YourUserControl();
ctrl.SaveClicked += (sender, e) =>
{
    // Put logic of your main form here
};

You can use event - the userControl will send event to the parent - and the parent will register as event listener.
