try this

C#

//this is only c# code
protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Session["CheckRefresh"] = Server.UrlDecode(System.DateTime.Now.ToString());
        }


    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        if (Session["CheckRefresh"].ToString() == ViewState["CheckRefresh"].ToString())
        {
            Label1.Text = "Hello";
            Session["CheckRefresh"] = Server.UrlDecode(System.DateTime.Now.ToString());
            string str = "your code will save here or call save() method here";

        }
        else
        {
            Label1.Text = "Page Refreshed";
                    }

    }
    protected void Page_PreRender(object sender, EventArgs e)
    {
        ViewState["CheckRefresh"] = Session["CheckRefresh"];
    }
