Hi,

I finally got it working and now I've a timer in my user control and I use client timer user control inside it. One wierd thing I'm seeing is when using it in a page which has another timer. The main page level timer fires every 2 seconds and calls a page method to check for any updates to the page(which has UpdatePanel inside it too). The user control fires every second to increment a counter. What is happening is, when using it in combination with the page level 2 second timer, the user control level timer fires multiple times in a second! As a result my counter jumps up too fast. The main window timer has been set using window.setTimeout and the user control timer is set using window.setInterval. Can't both be used together ?

Thanks in advance and regards

Navin,

you can do it using startup script (ScriptManager has the method you need).

or

you can do it using hidden field.,

I still dont quite understand the requirement - the timer is client component - if you need server side timer - use Timer control from ASP.NET AJAX.

But yes you can interop with client timer in any way you wish - the same way you would with any other client side component.

Thanks for clarification. My missin piece is that I want to enable/disable timer from code behind too depending upon some condition. I understand it has to be done from client side. How could I disable the timer, set a new value to increment and then reenable the timer when a new value is set for an asp:label in code behind(and so will be available after partial postback as I've UpdatePanel too on the page) ? Do I need to load a startup script to do that ?

Or should I use hidden fields to store such information and enable/reset/disable timer accordingly in its onTick callback ?

Thanks again and regards

Hi Navin,

You can start/stop timer from client code (js) or from c# code before rendering a page.

The client is client side component and has nothing to do with page lifecycle.

you can only enable disable from code behind - saying what enabled state will be for timer on page startup.

After this it lives on client.

Thanks. In my user control, I tried to make it a ScriptControl too with timer functionality and it worked. Thanks bunches!!! Now one thing I need to do to start/stop the timer from code behind of the user control itself. I've a GridView in my user control. When new data is available, I do databind and I want to stop the timer and start it again from the new value. I set its Enabled property to false but I guess it doesn't work because it needs a postback. How I could stop/start the timer in that manner ?

Thanks again and regards

Thanks for the response...appreviate it. I guess that explains the problem I'm seeing. Each instance of Timer user control(used in my own user control) was having same ID in page markup but generated ID was different when viewing page source. Still only one Timer user control was updating. I tried to create the Timer user control dynamically too and tried to assign a unique ID in page load but still the same issue :(

Is it simple enough to change the Timer user control to derive from Sys.UI.Control instead ?

Thanks again and regards

2010-03-27T02:42:42.779-07:00

Hi Navin

make sure you use different ComponentIDs for different components.

Also look at differences between Sys.Component and Sys.UI.Controls
component is not associated with user controls - it has no idea about markup - it is component - it works without knowledge about visual representation.
While Sys.UI.Control works with element (when creating it constructor must accept element to which the script have to be associated). So if you want to associate timer to control and make sure the timer script creates and disposes properly when associatred control is added / removed using AJAX UpdatePanel or your custom mechanism - then it is better to convert my sample from Sys.Component to Sys.UI.Control - in that case you will not have problems when adding/removing control during async postback/UpdatePanel.

2010-03-26T16:54:07.728-07:00

That's great...thank you. I'm trying to use it in another user control which could have multiple instances on the page. In that case, somehow only on one instance of user control it is working and not on the other. Any ideas ? BTW the page already has scriptmanager and updatepanel on it.

Thanks in advance and regards
