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; }    } }
