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 created a webUserControl timer.ascx, I have a page showTime.aspx I have added timer.ascx into ShowTime.aspx on drodown change I want to display the current time.
but I am getting this error
This type of page is not served. Description: The type of page you have requested is not served because it has been explicitly forbidden.
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?
I have a test web service called: MySimpleService.svc with a method called:GetUserNamesByInitials. below is the Linq to SQL code:
[OperationContract] public static string GetUserNamesByInitials(string initials) { string result = ""; [code]...
what I do is to type the user id in one textbox (TextBox3) and when I press the Tab key the result is shown in another textbox(TextBox4). The jQuery call works well with other methods that do not call the database, for example using this other web service method it works:
[OperationContract] public string ParameterizedConnectionTest(string word) { return string.Format("You entered the word: {0}", word); }
However with the Linq method it just does not work.
i have a web service that i use for the AutoCompleteExtender, let the below code show you what i'm trying to do: [Code]....
this method is called, and when it calls the method inside the Patients Class, it gets lost. does that mean that i can't use 3-tier approach with web methods?
I'm trying to call an action method in an MVC application using jQuery. Basically what I want is to take the value of a couple of input fields and call the action method by clicking a button, passing the values of the input fields as parameters. But I only get the value of the "number" parameter, not the "year" parameter.
function selectWeek() { $('#selectWeekButton').click(function (event) { var number = $("#selectWeekId").val(); [code]...
I checked the url with an alert, as you can see, and it seems to contain both values fine. But when I check the value of the year parameter in the action method it is null.Here are the input fields:
public ActionResult Edit(string number, string year) //etc...
I know that this looks like a strange thing to do instead of just binding fields, but the reason is that these input fields and their values is not the main purpose of this View. They're just there to select another week in this timesheet application. And besides, I'm going to replace the input fields with a jQuery calendar eventually, so I will still have to do something like this.
So what's the easiest way to do this, and why isn't it working as it is?
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); [code]...
I called the server side Method using AJax and inside Method iam going to Add the Media Player to Place Holder i debug the code every thing is ok but Place Holder is not Displaying any thing.
Here is my code of JQUERY
[Code]....
and Here is my server side Method
[Code]....
and in aspx code i just put the DataList for binding the Thumbnail Images and Place Holder control for displying the Media Player .
But Place holder is not going to visible after the calling sercer side Method to JQUERY. Is there any thing iam doing wrong.
I'm trying to implement a view tracking web service on my website. I'm using JavaScript because I want to exclude any search bots from my tracked views. The problem is I'm getting a "Unknown web method" error when I try to use jQuery to post to the web service I've created.
$(document).ready(function() {
$.ajax({ type: "POST", [code]...
The error is an ASP .NET error: Unknown web method TrackItemView. Parameter name: methodName.I've done this hundreds of times (seemingly), but I just can't see what I'm missing. I'm sure it's something small...
I'm using a custom AJAX based validation control to check user name availability from database. It's working alright in my development machine but in production server we are using Windows Authentication to authenticate by domain.The control is inherited from base validator and checks for user name availability from database perfectly but on form submission at Page.IsValid check it gives the following error.
remote server returned an error 401 unauthorized
Both the form and webmethod are in the same page/file. I even tried creating webmethod in a separate standalone webservice but error still there.
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 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 have a page with an update contentpanel, with 4 panels inside. Image buttons outside the update panel control control which panel is visible. I am trying to call an animation from a javascript function, but the animation doesn't work, everything else does.
I looked up the threads about this. But I couldn't do it...

In the content page, I have an ajax accordion pane with couple of panes. Within each of those panes there is 1 user control. Initially all the panes except the first one (AccordionPaneMain) is enabled. The first pane user control contains a form view . In formview itemcommand I am doing some processing and then was trying to enable rest of the panes by calling the function showPanes in the main page by using invoker method. My problem is, the method (showPanes) is getting executed but the panes are not enabled.
and I am calling the webmethod by javascript like this [Code]....
The result is, I get the error function running and I get "undefined error" alert.Am I calling the procedure correctly? I put a breakpoint on the webmethod and it.
I am trying to call an asmx service using the jQuery ajax call-
[Code]....
I have double checked the url of the service and spelling/case of the name of the method as well as the parameters in the dataStr.
I still get the error-<b> Description: </b>HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. review the following URL and make sure that it is spelled correctly.
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.
