.NET newbie alert

Using Visual C# 2008 Express Edition I have accidentally created a click event for a button. I then deleted the automatically-created method code, which resulted in an error saying that the function, which had now been referenced in the form loading code, could no longer be found.

Deleting the following line from the Form1.Designer.cs file's InitializeComponent() function...

this.btnCopy.Click += new System.EventHandler(this.btnCopy_Click);

... seems to do the trick, however, it makes me feel very dirty because of the following warning at the beginning of the #region:

/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.

I haven't been able to find a way to do this using the form designer, which I assume is the means implied by this warning. What is the correct way to do this?
