I have a java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).
var _countDowncontainer = 0;
var _currentSeconds = 0;
function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID);

If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.

I have overridden OnError method in the page:
public string script;
protected override void OnError(EventArgs e)
{
script = "alert('error');";
}
In the aspx, I have this:
<script type="text/javascript">
$(document).ready(function(){
<%=script %>;
});
</script>
I am simulating an error in Page_Load, but its not firing the alert. If I switch the code from OnError to OnLoad, it works great.

function DatalistFunction(argumentid) {
set_minimum_points_for_session = value;
SetSession(set_minimum_points_for_session);
Redeem(argumentid);
}
this is my code which i am calling on link button onclientclick event.
sometimes what happens is redeem function gets called first and then setsession function gets called. do i need to put some delay or something between the 2 functions, so that they run everytime in their own order

In GridViewData.aspx.cs I have a method I want to call inside a javacsript function.
[Code]....
Now hears the kicker, I am mostly using jqUery as UpdateInsertData() is a jquery Call and works fine. How do I use ValidateNameUpdateable to call jQuery to return the value from the c# method. . I believe this issue is with my jQuery Call as its just posting and I need to do a $.get or something?
function ValidateNameUpdateable()
{
$(document).ready(function ()
{
$.post("GridViewData.aspx")
});
}

I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for
example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer)
en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)
en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)
en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)
en System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)
Is there any way to know the webmethod that raised the error?

how to call a partial view from within a Javascript function? I've looked around the web, but all the examples that I have been able to find are examples using Ajax.ActionLink or Ajax.BeginForm.
When a user clicks on an item, I want to be able to hide/display some Divs and possible do other operations before calling the partial view. ActionLink doesn't appear to provide that ability. Depending upon the item the user clicked, I may be assigning the results of the PartialView to the same Div, or to a different Div.
What I'm looking to achieve, is to have an onclick handler associated with the item which performs whatever other operations might need to be done, then assign the result of the call of the PartialView to the appropiate Div. In some instances, the function might even be making two separate calls to PartialViews, to update the content of two separate Divs.

I need to get the count in a sub category dropdown, if it's zero then I turn off the visibility of the sub category.If I use the javascript OnChange event then my script fires before the web method, so I need to know how to fire my script AFTER the web method has fired please.

Below is my code and the order I need it to fire.

I have an ascx which contains a submit button for a search criteria and I am trying to call a validation function in a js file I've used throughout the site (this is the first time I'm using it in an ascx).
Now I've just tried this:
<script type="text/javascript" src="js/jquery-1.3.2.js"></script>
<script type="text/javascript" src="js/jsAdmin_Generic_SystemValidation.js"></script>
<script type="text/javascript">
$(document).ready(function () {
[Code]....
Now at first I was getting "Validate() is not a function" in firebug. Since I did that alert testing, I am getting the first alert, then nothing with no errors.

I am trying to call a Page Method using AJAX.
See the code
<asp:Button ID="btn_upload" runat="server" CssClass="btnEffects" Text="Upload"
onclick="btn_upload_Click" OnClientClick="return Validate();" />
Validate method is supposed to return true/false. The code for Validate method is
<script language="javascript">
function Validate()
{
var filename = $get('<%= txt_filename.ClientID %>').value;
PageMethods.IsValidFile(filename,OnSuccess, OnFailure);
// IsValidFile is a Page Method of bool return type
}
function OnSuccess(result)
{
if ( !result)
{
alert('File '+ $get('<%= txt_filename.ClientID %>').value + ' does not exist');
return false;
}
else
{
return true;
}
}
function OnFailure(error)
{
}
</script>
My problem is that even after showing the alert 'File somefilename does not exist'. The whole page refreshes (i.e, postback happens)
