    My requirment is that I want to run a function in a class automatically every 30 days. But as per my understanding, the asp.net application runs only when someone request any pages in that site through the browser. Is it correct? Can i set any triggers in asp.net? Thanks and regards, Hogan

    That doesn't sound like a good job for a webserver to be honest. Can't you wrap the method call and use windows scheduler, or a windows service to run the call for you?

      Sorry I am not an expert. But it is the client-server technology. I think, the executables in the bin folder only work whenever a browser requests any pages in that site. Hope I am clear now. Thanks, Hogan

        I think the timer control won't work. The timer works only the page which contains the times runs. Thanks Hogan

        Try this link

        If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

              i was using the timer control in website just for the practise purposes.I saw , the timer control is auto executing after it's time interval if it is a ajax enabled website. If it is a asp.net we site(partially enabled ajax website , i mean , in the asp.net website , i am dragging the ajax controls) then the timer control is not working , it works if in the form load i write protected void Page_Load(object sender, EventArgs e) { Timer1_Tick(sender, e); } the source file code <form id="form1" runat="server"> <div> &nbsp;<asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> </div> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick"> </asp:Timer> <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" /> </Triggers> </asp:UpdatePanel> </form> I am unable to understand where i am wrong ?

              If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

                            protected void Page_Load(object sender, EventArgs e) { Timer1.Tick += new EventHandler<EventArgs>(Timer1_Tick); Timer1.Enabled = true; } protected void Timer1_Tick(object sender, EventArgs e) { i += 0; Label1.Text = i.ToString(); } I think after writing the code , the control should auto execute the timer_tick function. But the control is not comming there. the time interval is 1000.

                                  Label text was Label initially at runtime it is Label after form load.

                                  If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

                                    you are using ajaexenabled websites na !!!! use ajax enabled sites. and dont initilize local variable inside the Timer_Tick(), because it will remain same :) let me know if any problems

                                        i am not using the ajax enables website , it is a asp.net site , there i am using the timer control. Is it mandatory to use the ajax enabled website , in order to use the timer control?

                                        If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!
