I checked the errata and found no mention of this, i may be wrong but i had to insert the two 1's in this C# code, in the code behind of the Timer Demo. The book didnt mention this ;), if its just in there to test us, then sorry for bringing it up.

Chapter 10: ASP.NET AJAX
Page: 334

protected void Timer1_Tick(object sender, EventArgs e)
{
UpdateLabel1();
}

private void UpdateLabel1()
{
Label1.Text = System.DateTime.Now.ToString();
}

protected void Button1_Click(object sender, EventArgs e)
{
UpdateLabel1();
}

Why would you need to add those 1's? You should remove them from the method signature instead, as they didn't have to be there in the first place. This is how the code from the book looks:

Code:

VB.NET
Protected Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) _
       Handles Timer1.Tick
  UpdateLabel()
End Sub 
Private Sub UpdateLabel()
  Label1.Text = DateTime.Now.ToString()
End Sub 
C#
protected void Timer1_Tick(object sender, EventArgs e)
{
  UpdateLabel();
} 
private void UpdateLabel()
{
  Label1.Text = System.DateTime.Now.ToString();
}

As you can see, the methods are called UpdateLabel, not UpdateLabel1.

Cheers,
