Jeff,

Briefly, a delegate tells .NET what method you want to use to handle an event. Say you have a button and you want it to do something when it's clicked.

First you have to define the delegate, to tell .NET which method is your eventhandler:
this.MyButton.Click += new System.EventHandler(this.MyButton_Click);
... then you define the eventhandler method itself:
private void MyButton_Click(object sender, System.EventArgs e)
{
    // code to handle the click goes here
}
