write this code on you Page_Load event

C#

public List<datetime> DateArray { get; set; }
 protected void Page_Load(object sender, EventArgs e)
        {
            this.DateArray = new List<datetime>();
            if (ViewState["DateArray"] != null)
                this.DateArray = (List<datetime>)ViewState["DateArray"];
            this.DateArray.Add(DateTime.Now);
            ViewState["DateArray"] = this.DateArray;
            if (!IsPostBack)
            {

            }
        }
</datetime></datetime></datetime>
