Put a Timer on the web form

[C Learner]

Hi,
I'm new to ASP.NET. I have an WebForm1 which contained a ListBox1. I have
drag a Timer on the form. In the timer1_Elapsed() function , I have add the
line ListBox1.Items.Add("haha"). But when the timer elapsed, it called that
line of code, but the ListBox1 didn't show "haha".
Would you tell me what I have missed?

I'm using C#/ASP.NET

Best regards,
C Learner

This is a "classic ASP only" NG.

Please try your luck in a dot.net NG.
