If you visit this [URL] and then click on the link like the image below you'll see in-line pop-up DIV which displays a busy status of Ajax callback before it displays the information. So, the information is not there yet until you click on the link.
I'd like to do the same but ASP.NET and jQuery.
I am developing web application and in application i need to make call of jQuery using .ajax(); method with datatype is set jsonp. Now all works well with limited data but problem start to occur when data size is increasing......
View 7 RepliesIs it required to use a RESTful service to be able to make a ajax call to a wcf service (for example: by using WebInvoke attribute on Operation contracts). Once a service is made RESTful by adding a webHttp binding on the service host, can the host have other endpoints as well? (wsHttp or netTcp). Is it required that the aspNetCompatibilityEnabled be set to true for a service that has webHttp binding (and can this setting coexist for other endpoints). I understand I can use both JQuery and ScriptManager for making WCF calls on the client. Why should I use one over the other?
View 1 RepliesI have a Page that expects a POST Request and returns some JSON. Essentially it's an .ashx Page, but that doesn't really matter.
When using jQuery, I would use jQuery.Post with "json" as dataType to simply make the POST request and get an object back. However, for the current project I mainly use ASP.net AJAX and I don't want to add jQuery just for the call.
For ASP.net AJAX, I only found information on how to call a "traditional" web service though, which means adding a asp:ServiceReference to the ScriptManager and having a "real" Web Service at the end.
Is there a simpler way to make a POST call to a Page? I could live with getting the raw JSON and then manually eval()ing it, but I don't want to create a full asmx web service (deploying them on SharePoint is a bit painful, and my ashx handler works fine)
I tried to take advantage of jQuery AJAX call to enhance user experience but I am facing a tricky problem.
When the user does nothing for a period of time, e.g. 30 minutes to reach authentication timeout, making AJAX call becomes the problem. The server side will return login page and display in my target div section. The simplest solution I can think of is to inject a dummy tag in login page, and when detecting such dummy tag then use javascript to redirect to login page. But this means that I have to do that every time I make AJAX call.
For an Umbraco project, I am trying to make a simple Ajax call.. I can't use PageMethods because I need to make the call from inside a UserControl.. I tried to do it via web service call like this:
Web service method:
[System.Web.Script.Services.ScriptService]
public class MapService : System.Web.Services.WebService
{
[WebMethod]
[Code]...
The problem is, "MapService.GetCities" method doesn't get invoked..
What might be the problem here?
Alternatively, what is there any better way to make these kind of Ajax calls in a User Control?
I am just wondering that, is there anyway to make an Ajax request using jquery ("$.ajax") and making partial rendering without using the .NET Ajax framework (without script manager).
I have tried this before, but it's executing the page_load every time and not reaching to the pagemethod.

I've created a sign up form in a normal .aspx page, with some TextBoxWatermarkExtendes, PasswordStrength, RegularExpressionValidator, and more..it worked perfectly..I have inserted it all inside the modal content div in this SimpleModal:http://www.ericmmartin.com/projects/simplemodal-demos/(the OSX style dalog)
the First problem:I have a toolkit script manager, and an update panel surrounding the "username" textbox, with enabled autopostback, so it checks if user is taken or not when the textbox looses focus and shows a message in label..when it runs for the first time (when it's working) first of all, the passwordStrength control doesn't work, secondly, after I type something in the username textbox and make it lose focus (press tab or click outside), it's watermark text of course gets deleted when i focus on it, and another watermark text from another textbox gets deleted (i dont know why) SO after like 1 or 2 seconds, the text I wrote gets deleted and replaced by the watermark, for BOTH textboxes that had watermarks
Second problem:the first time, the it works normal, but when I close the modal and open it again, the textBoxWatermark changes to a normal text inside the textbox, even the "Sign up" button stops working, and expression validators and required validators and stuff stop working..
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 am searching for a way to create a grid (from some kind of jquery grid plugin didnt choose one yet)

I have this Aja.svc in my root folder
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Aja
{
[WebGet]
[OperationContract]
public string Hi()
{
return "hi world!";
}
}
and I'm trying to do this: $.get('Aja.svc?method=Hi', function(d) { alert(d.d); }); In firebug I see that the result is HTTP Error 404.17 - Not Found The requested content appears to be script and will not be served by the static file handler. I use .net 3.5, jquery 1.4.4
I created a number of standard WCF Services (Service Contract and Host (svc) are in separate assemblies). I fired up a Web Site in IIS to host the Services (i.e., address is [URL]). Then in my Web Site project I added the reference. I am able to call the services normally. I am needed to call some of the services client side. Not sure if I should be looking at articles calling WCF services through AJAX, JQuery, or JSON enabled WCF Services. Some of the changes I made was adding the following to the Operation Contract:
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "SetFoo")]
void SetFoo(string Id);
Then this above the implementation of the interface:
[AspNetCompatibilityRequirements(RequirementsMode =
AspNetCompatibilityRequirementsMode.Allowed)]
Then in the service webconfig I have this (parens are angle brackets):
<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
<baseAddressPrefixFilters>
<add prefix=[URL]>>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
Then in the client side I attempted this:
<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
<compositeScript>
<Scripts>
<asp:ScriptReference
Path=[URL]/>
</Scripts>
</CompositeScript>
</asp:ScriptManagerProxy>
I am attempting to call the service like this in javascript: wcfservices.SetFoo(string Id); Nothing is working. If it is idea or a better solution to call JSON enable, JQuery, etc.... I am willing to make any changes.

How to use jQuery to call ASP.NET AJAX Page Method?
View 1 RepliesI have the following jQuery event that gets fired every time an anchor is clicked. How can I pass a asp.net control (lets say a panel called "pnl_info") as one of the parameters, in addition to the "target" parameter i'm already passing?

Let say I got the following button : <asp:Button ID="btnSearch" runat="server" /> and the following button event handler: Protected Sub btnSearch_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSearch.Click ow, with JQuery, can I call the button event handler ? What I mean is that I don't want the page to refresh, so it's kind of Ajax call. I don't want to simulate the click but that on click the button event handler is call.

View 1 RepliesI am new to jqGrid and I have found it difficult to follow the documentation jqGrid Documentation / I cannot figure out how to call a WebMethod when setting up the JQGrid. I have been successful in making an Ajax call to get the data and then setting up the JQGrid with local data. I think its an extra step in the setup process and that I should be able to provide the path to the webmethod using the url property. The editurl property is the same way. I am never actually receiving the post to the server. Attempted JQGrid Setup
function GetData()
{
$('#list').jqGrid({
type: "POST",
url: "Default.aspx/GetUsersJSON",
datatype: "json",
height: 250,
colName: ['Username', 'Email'],
colModel: [

}).jqGrid(
'navGrid',
'#pager',
{
edit: true,
add: true,
del: true
});
}
WebMethod
[WebMethod]
public static string GetUsersJSON()
{
var users = new List();
using(UserAdministrationSandboxDataContext uasd = new UserAdministrationSandboxDataContext())
{
users = uasd.GetUserList();
}
JavaScriptSerializer serializer = new JavaScriptSerializer();
return serializer.Serialize(users);
}
Current Code I got it working correctly now, but I still have one final question. Why did I have to set the 'repeatitems: false' in order to display the content? Some of the caveats to get this to work include the different ways to setup the ajax request. (Ajax: type) is (jqgrid : mtype) (Ajax: contentType) is (jqgrid : ajaxGridOptions: { contentType: })
And finally understanding the documentation from the documentation on how to setup the JSONReader.
function GetUserDataFromServer()
{
$('#list').jqGrid({
url: "Default.aspx/GetUsersJSON",
mtype: 'POST',
ajaxGridOptions: { contentType: "application/json" },
datatype: "json",
serializeGridData: function (postData)
{
return JSON.stringify(postData);
},
jsonReader: {
root: function (obj) { return obj.d; },
page: function (obj) { return 1; },
total: function (obj) { return 1; },
records: function (obj) { return obj.d.length; },
id:'0',
