Set DefaultButton for Enter KeyPress in ASP.NET

Have you ever tried to set the default focus and default submit button on an ASP.NET 2.0 Password Recovery Control? It takes some work, yet I was able to put this example together thanks to Spannjaars.com, Ellipse in the asp.net forums, and Google.

Aspx page

<asp:PasswordRecovery ID="PasswordRecovery1" runat="server"OnVerifyingUser="PasswordRecovery1_VerifyingUser" />

Code behind (.cs)

protected void Page_Load(object sender, EventArgs e)
{
   // The first time our page loads we place the cursor in the
   // User Name textbox and make the Submit button the default button 
   if (!IsPostBack)
   {
      Page.Form.DefaultButton = PasswordRecovery1
         .FindControl("UserNameContainerID$SubmitButton").UniqueID;
      Page.Form.DefaultFocus = PasswordRecovery1
         .FindControl("UserNameContainerID$UserName").ClientID;
   }
}

protected void PasswordRecovery1_VerifyingUser
                  (object sender, LoginCancelEventArgs e)
{
   // This event fires after the User Name is entered; Place the cursor 
   // in the answer textbox and make the Submit button the default button 
   Page.Form.DefaultButton = PasswordRecovery1
      .FindControl("QuestionContainerID$SubmitButton").UniqueID;
   Page.Form.DefaultFocus = PasswordRecovery1
      .FindControl("QuestionContainerID$Answer").ClientID;
}
