hey every one i am using atlas in my webpage..but i had a question ..is there a way to call a javascript function that you wrote on page refresh sort of say..for example i have a dropdown that you can choose which category you would like to see ...when you choose your category ..using atlas i refresh only the portion of the page..so the whole page doesnot get refreshed...but i would like a javascript function that i wrote to get call as soon as atlas finishes rereshing the page ...can you guys guide me on how to do this ?

hello.

currently, the only indicator of a refresh is the inpostback property of the pagerequestmanager. though i haven't tried, it'd handle the propertyChange event fired by the pagerequestmanager...

oh, and here's a quick sample that is working here:

<%

@ Page Language="C#" %>

<!

DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<

script runat="server">

void h(

object s, EventArgs a)

{

txt.Text = DateTime.Now.ToString();

}

</

script>

<

html xmlns="http://www.w3.org/1999/xhtml" >

<

head runat="server">

<title>Untitled Page</title>

</

head>

<

body>

<form id="form1" runat="server">

<atlas:ScriptManager runat="server" id="manager" EnablePartialRendering="true">

</atlas:ScriptManager>

<atlas:UpdatePanel runat="server" ID="panel">

<ContentTemplate>

<asp:Literal runat="server" ID="txt" />

<asp:Button runat="server" ID="bt" OnClick="h" Text="try" />

</ContentTemplate>

</atlas:UpdatePanel>

</form>

<script type="text/javascript">

Sys.Application.load.add( onLoad );

function onLoad()

{

var page = $object("_PageRequestManager");

page.propertyChanged.add( changed );

}

function changed( obj, args )

{

if( args.get_propertyName() && obj.get_inPostBack() == false)

{

alert(

"refreshed" );

}

}

</script>

</

body>

</

html>

 

thank you guys..the last one worked :)

This is awesome, ever since moving from MagicAjax i have been missing this client triggered javascript feature on refresh. I used to have to rely on a timer that would poll a hidden field every second looking to see if the server had set it to a specific value. I shudder at the thought. Now i can just automatically trigger the code on the client. Cheers Luis.

I have had a look for some docs on _PageRequestManager but can't find any, is this another one of those "special" objects, like the cancel commands?

djeeg:

well, in fact all credits should be given to Garbin since this was inspired by his previous post that you can check here (maybe it'll help you in other scenarios):

btw, go read his blog. there you can find some great posts about atlas.

hello again.

btw, just one little correction: in the if section, it shoudl be

args.get_propertyName() == "inPostback" && ....

hi one note if i add this

args.get_propertyName() == "inPostback" && ....

 

like you mentioned on the topic above it wont work any more

hello again.

err...  try "inPostBack"...
