in desktop app, this is the code
but in web app it doesnt work, why?
tnx in advance

    protected void Page_Load(object sender, EventArgs e)
    {
        t = 5;
        Label1.Text = DateTime.Now.ToString();
        Label2.Text = DateTime.Now.ToString();
    }
    protected void Timer1_Tick(object sender, EventArgs e)
    {
        Label2.Text = DateTime.Now.ToString();
       
        Label3.Text = t.ToString();
        t = t - 1;
           
            if (t == 0)
            {
                Label3.Text = "gdfgdg";
                t = 5;
            }
    }

It doesn't make sense to use a server side timer in an ASP.NET application. The ASP.NET application will just execute the codebehind and output the page. The Timer Tick event is therefore redundant.

You will need to translate the code you want done in the timer tick event to javascript which runs on the client side.

i found the solution... pls see below.
hope in some questions for the newbies like me would help in the future

    protected void Page_Load(object sender, EventArgs e)
    {
        if (Session["TestVal"] == null)
        {
            Session["TestVal"] = 5;
        }
        Label1.Text = DateTime.Now.ToString();
        Label2.Text = DateTime.Now.ToString();
    }
    protected void Timer1_Tick(object sender, EventArgs e)
    {

        Label2.Text = DateTime.Now.ToString();
        Session["TestVal"] = Convert.ToString(Convert.ToInt32(Session["TestVal"]) - 1);
        Label3.Text = (string)Session["TestVal"];
        if (Convert.ToInt32(Label3.Text) == 0)
        {
            Label3.Text = "gdfgdg";
            Session["TestVal"] = 5;
        }
    }

***** RE-SEND

    protected void Page_Load(object sender, EventArgs e)
    {
        if (Convert.ToInt32(Session["TestVal"]) == 0)
        {
            Session["TestVal"] = 5;
        }

        Label1.Text = DateTime.Now.ToString();
        Label2.Text = DateTime.Now.ToString();
    }
    protected void Timer1_Tick(object sender, EventArgs e)
    {

        Label2.Text = DateTime.Now.ToString();
        Session["TestVal"] = Convert.ToString(Convert.ToInt32(Session["TestVal"]) - 1);
        Label3.Text = (string)Session["TestVal"];
        if (Convert.ToInt32(Label3.Text) == 0)
        {
            Label3.Text = "5";
            Session["TestVal"] = 5;
        }
    }

Again, it won't make a lot of sense, because you're not going to be seeing the changes as the label's text gets updated by the changing values, unless this is in an UpdatePanel in which case it's usually best to divulge such information when asking a question.

[basti42]

the label is updating and it is inside the updatePanel object

Thank you.
