Winforms user controls custom events

Question

Is there a way to give a User Control custom events, and invoke the event on a event within the user control. (I'm not sure if invoke is the correct term)

public partial class Sample: UserControl
{
    public Sample()
    {
        InitializeComponent();
    }


    private void TextBox_Validated(object sender, EventArgs e)
    {
        // invoke UserControl event here
    }
}

And the MainForm:

public partial class MainForm : Form
{
    private Sample sampleUserControl = new Sample();

    public MainForm()
    {
        this.InitializeComponent();
        sampleUserControl.Click += new EventHandler(this.CustomEvent_Handler);
    }
    private void CustomEvent_Handler(object sender, EventArgs e)
    {
        // do stuff
    }
}

Aside from the example that Steve posted, there is also syntax available which can simply pass the event through. It is similar to creating a property:

class MyUserControl : UserControl
{
   public event EventHandler TextBoxValidated
   {
      add { textBox1.Validated += value; }
      remove { textBox1.Validated -= value; }
   }
}
