Solution 2

You need to check for IsPostBack in your Page_Load code:

C#

protected void Page_Load(object sender, EventArgs e)
{
   if(!this.IsPostBack)
   {
      long i = 1;
      foreach (byte b in Guid.NewGuid().ToByteArray())
      {
         i *= ((int)b + 1);
      }
      TextBox1.Text = string.Format("{0:x}", i - DateTime.Now.Ticks);
   }
}
