I have a page that calls a webservice from JavaScript using the approach described in this article: [URL]
This is working fine. The problem is when the page causes a postback before the end of the execution of the webservice's method. When that happens, the succeeded callback method never gets called. Does anyone know if there's a workaround to this?
I've tried a bunch of different examples and still can't get this to work. I have a jQuery GalleryView control I'm using and I simply want to log impressions. I set up a webservice that works, but I can't figure out how to get it to work in javascript. I have verified that the webservice is working as expected.

I just wana know that can I bind an asp listview via javascripts by calling a webservice in c#??
View 2 RepliesI get this error "The server method xxx timed out." calling a WebService that internally does a hard query to the database, and takes some time. I use this method to change the webservice timeout, but it does not seems to do anything (the timeout errors appears in less than a second).
MyService.set_timeout(100000);
I want to add items to a dropdownlist with values return by a webservice which will be called from javascript without cascading extender...

But my function is not going to Hello() soon after calling SetOCXVariables()
After my 'P' comes undefined and does the remaining, it goes to hello()
why is this happening?

Now i dont understand why my Autoextender is not call the webservice. I have tried callin the webservice from button click event...it works but not using AutoExtender..
In IIS I have a virtual directory with only windows authentication enabled. From Javascript I call into a ASMX webservice. From the ASMX webservice I make a call to the SharePoint Search.asmx Webservice. whatever I try I keep getting the followin gerror message:
"The request failed with HTTP status 401: Unauthorized"
I use the following code to call the SharePoint webservice

My web.config settings are:

The Sharepoint farm is configured to use NTLM authentication.
Strangely everything works when I am testing in Visual Studio using the builtin webservice, but when I deply to my local IIS or Test Server it breaks.
I ultimately need to show countries in one drop down then states/provinces drop down of the previously selected drop down. I'm sure everyone has seen this many times. My page shows the countries but does not show values in the province/states drop down. It's as if the webservice is never run. I've tried removing and adding the ajaxtoolkit reference. The tableadaters run simple working sql code. I'm really at a lose here.
default.aspx:
...
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>

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

Or is there any simpler solution ?
View 1 RepliesI am planning to use a Javascript call to a WebService to retrieve data from the database. At the moment I am using Ajax to do this. But since the Ajax is slowing down the performance of my application. I have read in some article that even though Ajax only refreshes the Update panel contents, Ajax does a full round trip to the server. What I need to know is how can I populate a Grid from data coming from a WebService via a Javascript call.
View 3 RepliesAfter watching [URL] learning guide in accessing Web Service from JavaScript[/url] I was doing the same thing in order to test it. And found out that in my JavaScript I don't have any WebService in my IntelliSense. Such thing happens if I create WebService and WebSite either in one common solution or in the different.
View 23 RepliesI had a standard ASP.NET page where I had a some client side Java script make some controls visible/enabled if a checkbox was clicked or not.
[Code]....
Now I would like to move this same WebForm functionality into a AJAX Control Kit TabControlPanel
[Code]....
Here is what I have tried, but it won't compile. I get the following error. Where do I put the script and how do I reference controls in the AJAX TabControlContainer?
Error 10 'ASP.default_aspx' does not contain a definition for 'Email2Checkbox' and no extension method 'Email2Checkbox' accepting a first argument of type 'ASP.default_aspx' could be found (are you missing a using directive or an assembly reference?) C:InetpubwwwRootAjaxTestSiteDefault.aspx 458
So I have this idea of creating a asp.net user control, to handle all forms of modal popups (whether it be error handling, forms, dialogs, etc).
I already created this before, placing the user control in the top master page, exposing it to all content pages, so I could do something like:
Master.Popup.ShowException(Exception);
And the usercontrol itself would have the necessary markup to look like a modal dialog, and in the show method just do a .Visible = true.
This is all fine, but I've started thinking of implementing a bit of style with jquery. I'd like for the usercontrol to have some sort of jquery animation on show. But I don't know how to go about achieving this, as I don't know how I would call that jquery function from the codebehind instead of the popup.visible = true.
I'm trying to implement the cascading dropdown from the toolkit. 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.
Below is my code and the order I need it to fire.
[WebMethod]
public CascadingDropDownNameValue[] GetSubCats1(string knownCategoryValues, string category)
{
StringDictionary kv = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues);
int CategoryID;

I'm calling a webservice using jQuery with .ajaxHere are the data parameters for the call:
var parameters = "{'Titre':'" + Titre + "','Description':'" + Description + "','Contact':'" + Contact + "','VilleId':'" + VilleId + "','QuartierId':'" + QuartierId + "','UserId':'" + UserId + "'}";
It works fine. But when parameters Description or Titre contain the ' character , no call!!!
Does anyone have an idea how can i make it work even with apostrophe character in Titre and/or Description?
I'm trying to pass a javascript object array back to a vb .asmx web service.
I can't even tell you how many different things I've tried, so i'm confused more than when I started.
Below is an example of the client side code I am using.
[Code]....
I'm adding my script reference in my vb page as follows, and can access other web methods fine.
[Code]....
how to be able to access these objects within the web service method. I need to be able to iterate though all the people from the javascripts array so that I can do some other functions, such as validation, adding them to a database, etc.
I know i've seen a tutorial for this, but can't locate it anymore. I have a class Employee in c# side, I also have a webservice where I pass in an ID# and an Employee object is returned. Now I want this object returned to Javascript code, I know I've seen it done before, can someone point me to a tutorial that shows something like this being done. I'm using the MicrosoftAjax.js file.

I'm calling a web service called GetTooltip from inside Javascript. However, since the web service is called asynchronously, it doesn't wait until I get the return value from the web service, before it continues again. This is a bit of a problem for me, since the web service is in a for-loop. How do I make the Javascript wait until I hear back from the web service, before letting Javascript continue the for-loop?

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
