Calling JavaScript Function From C#

Dear Team

i am using VS2005 ASP.NET 2.0 C# JavaScript AJAX
i want on timer tick in side uodate panel to call javascript Function()
so how can i do that.

thank you

I would very much like to know how to do that too.

I have a ModalPopup containing SimpleViewer, and I need to set the path to an xml file when the user clicks an imagebutton, but as there is no postback going on I can't add that path or whatever it might be to the JavaScript block.

So I relaly need for the JavaScript block to be "loaded" and executed when the user clicks one of many buttons and then load the javascript based on that.

This is a great resource on using a TimerControl with an UpdatePanel:

http://ajax.asp.net/docs/tutorials/IntroToTimerControl.aspx

However if you want to execute a JavaScript function before/during/after an UpdatePanel is refreshed you will need to explore the PageRequestManagerClass:

http://ajax.asp.net/docs/ClientReference/Sys.WebForms/PageRequestManagerClass/default.aspx

You can add the following Javascript to a page:

<script type="text/javascript">
Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(pageLoaded);
function pageLoaded(sender, args) {
if (args.get_panelsUpdated().length > 0){
alert('a panel was just updated!');
// doSomeFunction();
}
}
</script>

Cheers,
Al
