I'm trying to make some calls to a WebService I did exactly what is described in this article [URL] Looking at the console of firebug I could see that my function was executed and returned the expected data, but my callback functions (OnComplete, OnError, OnTimeOut) are never executed. Whats wrong? Here is the code (same code of the article)
Service.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
[WebService(Namespace = "[URL]")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
[System.Web.Script.Services.ScriptService()]
public class Service : System.Web.Services.WebService
{
public Service () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string HelloWorld(string strNoOfData)
{
return strNoOfData;
}
}

I have a callback handler done in VB which works fine with this code:
<!-- Div Outside Form --> <div class="container"> <form id="querydata" runat="server"> <asp:DropDownList runat="server" ID="myddl" AutoPostBack="true" OnSelectedIndexChanged="myddlhandler">
[Code]....
It the postback no longer works. Is how asp is supposed to work? Or is it some magic error that only works for me? And most importantly, if asp is not supposed to work this way, how should I be doing this?
I'm using AJAX Page Methods, but I can't seem to be able to pass the needed parameters:
function getFavStatus() { //favs is a list of DOM <imgs> that I want to modify their img.src attribute for (i = 0; i < favs.length; i++) { PageMethods.isFavorite(favs[i].alt,setFavImg(favs[i])); } } function setFavImg(fav, response) { fav.src = response; } The problem that I can't figure out is how to use the "response" from PageMethods, AND pass the DOM object to the callback function. I've also tried doing something like this: function getFavStatus() { for (i = 0; i < favs.length; i++) { PageMethods.isFavorite(favs[i].alt, function (response) { favs[i].src = response;}); ); } }
In this case, the response works properly, but i is always > favs.length, because it has already iterated through the loop... Edit: My PageMethods.isFavorite signature is: [System.Web.Services.WebMethod] public static string isFavorite ( string p_id )
The problem is, the binding '<%= JOB_CODETextBox.ClientID %>' doesn't work, it returns the same binding expression after renderign instead of replace it with the actual client id!
I'm using ajax to call a webmethod from javascript. The call is successfully made to the webmethod but I'm not able to access the parameters I passed to the webmethod inside of the "OnSucceeded" callback method. I need access to those params because I need to perform more tasks on the client side when the webmethod returns. I'm assuming that the params are returned inside "usercontext", but the value of that param is "null" How can I have access to those params?
Here my sample code:
function OnSucceeded(result, usercontext , methodName) { alert( result + ' The value of usercontext is: ' + usercontext); } function OnFailed(error, userContext, methodName) { alert('Attempt to delete semantic attribute from page failed!'); } function deleteSemanticAttribute() { var username = 'xxxxxx'; var password = 'yyyyyy' PageMethods.GetMyData(username, password, OnSucceeded,OnFailed); } [WebMethod] public static string GetMyData(string username, string password) { return "This is my test application!"; }
I wanna assign a JavaScript CallBack function to an UpdatePanel which will be gets called when the UpdatePanel finishes its tasks. After, the UpdatePanel will be sending a string as a result. This JavaScript CallBack function will have to process this resulting string.
Let's say you have a Javascript function that calls a web service method. So that webservice completes and calls a callback function, which has the result.
How do I get that result back into the original function that called the web service method? Essentially, I'm trying to "synchronize" an asynchronous call.
Update:
This is what I'm trying to do. I'm validating based on the return value of a web service.
I understand that probably this is not good forum for asking this question, but I'm a bit dissapointed, and I don't know where I can found answer to my question. Here is my problem. I've got a page that has dynamically loaded content with innerHTML like below:
[Code]....
Everything works fine .. since I wanted to have gif shown when page content is loading. But now I would like to after loading innerHTML content to execute javascript function to create pieChart of something. The problem is that I have to use document.getElementById()function, but it does not works with content loaded dynamically. I mean, Lets say that inside page loaded by innerHTML we've got a form which id="A" when instead pieChart() in above code i will use document.getElementById('A') it does not return my form. I've checked this in IE7 with no effect, ffox also does not seems to work. The only one browser that works at the moment is Chrome.
AutoCompleteExtender (4.1.4.0) in update panel in user control (ascx) and webservice under his ascx.vb and doesn't works.
So I've tested the same markup and webservice method in a simple aspx page and works, so I've some doubt:
- AutoCompleteExtender works in ascx file with webservice function under his code?
- AutoCompleteExtender works in an update panel?
I've always problem to create webservice method using wizard on the control, it return always: Cannot create page method GetCompletionList because no CodeBehind or CodeFile was found! - but I've CodeBehind file..sure!
I have an asp web app contains ajaxtoolkit's controls. Everything is working fine on VS Development Server, but doesn't on IIS7 (win 2008).
The AjaxToolkit's scriptcombine sometimes is not working (resulted http 404 status code on browser). Maybe causes by long TSM_HiddenField query string on complex toolkit's controls.
Clicking the buttonfield deletes the record just fine. Clicking the LinkButton doesn't work. I get a postback and the grid is shown as empty and no record is deleted. Seems like an empty databinding. I have tried to create a custom OnClick, OnCommand event for the LinkButton, but neither are fired. The OnRowCommand isn't fired either.
I have two web servers plus my desktop. I use Visual Studio 2008 to generate asp.net pages. I put a statement like:
response.write("Testing if function: " & if(0>1,"true","false") & "<br />")
in a code-behind file (test.aspx.vb). When I type it, Intellisense clearly recognizes the IF function and gives me guidance on the two overloaded versions. When I Build the page, it gives no errors, but when I View in Browser, I get an error: "BC30201: Expression expected." with the compiler details pointing to the IF. When I run the page on my test server, I get the same result, but when I run it on my production server, it works just fine.
I have a application that connects to a remote sql server. I am able to create users and they are stored in the DB. Then I can go to the login page and login. But after a while, I am unable to log in and it just sits at the login page. The user is still in the DB
if I set roles in a siteMapNode with title "Analiza" it works fine, the link is not shown in the navigation... but if I set roles on any of "karneki" siteMapNode the links are still visible...
Is it even posible to restrict access to lower links based on user role?
I have made a Website in Vs2008 on XP.Did the Url rewriting for this website by using Intelligencia.UrlRewriter.dll.It works fine locally.in my webconfing i did it like this ->
i have a gridview that binds data after changes were made (delete,update..) and it's all done with the c# method DataBind() and i don't know why FF shows the changes but in IE8 the grid remains the same and only if i navigate back and refresh, then i see the changes.
I'm making a website in ASP.NET 4.0 where I make use of the RequiredFieldValidator control to validate a wizardstep.It works perfectly with Javascript enabled, but when I turn it off (in my Firefox) it just goes to the next step.We don't do a Page.IsValid check, but we don't do much on the "next button clicked" event either.Certainly not something that is forcing it to go to the next step.
As the title of this post already mentioned, I'm using a modal popup window to edit rows in the gridview. One column in the gridview contains an URL code. When I fire the edit button a popup opens and show the URL in a textbox in this format: [URL]
When I am using the Server.HTMLDecode function, the modal popup doesn't close anymore.
I am using the following code:
[Code]....
The funny thing is, when I change it to: txtURL.Text = row.Cells[3].Text; then I can close the modal popup, but unfortunately it is not decoded.
I have an aspx page with two buttons, one of the buttons has an OnClick attribute to a function that should be run when clicked. When the other button is clicked there is an if statement checking if the page is a postback, if it is then I run some statements that need to be run when that button is clicked. That postback button works fine. However, the other button, when it's clicked the function it's supposed to call never executes, and the statements inside if (Page.IsPostBack) get executed instead. What can I do to fix this? Is there a way to make the button that calls a function not do a Post back?
I am using Ajax Validator call out extender to validate a web form. The error messages are displayed as expected. But I am able to save the form with data that should not have been entered. For ex: for a number field, I type in "sdsd" and the ajax control displays a pop up displaying the error message "Numbers only allowed"..
but at the same time, I can click on the submit button with the text in the number field... at which time, the web page displays error as I am trying to insert a text in a data type int field. I either have to clear the field on pop up error display or not let the user click submit when ajax validator is active. whats the best way?
Have a project that was created in Visual Studio 2008 and deployed to a 64-bit Windows 2003 server. This application references a 32-bit Interop.ActiveDs.dll. The applications were originally compiled for 'Any CPU', however, explicitly compiling as 'x86' doesn't solve the problem. The project targets the 3.5 framework.
The server is running IIS 6.0 in 64-bit mode. When we deploy the version compiled in Visual Studio 2008, the app runs perfectly fine; all pages show up. In retrospect, this is actually surprising.We migrated the application to Visual Studio 2010 (we did not change the targeted framework) and redeployed. Now we get a BadImageFormatException loading Interop.ActiveDs.dll. Which actually makes more sense than the 2008 version running.To solve the problem, we set Enable32bitAppOnWin64 to true and ran aspnet_regiis.exe -i from the 32-bit folder of the 2.0 framework (as per various instructions on the web). In IIS, web service extensions, there were two versions of ASP.NET 2.0, one for 32-bit and one for 64-bit. We prohibited the 64-bit version, restarted IIS, and launched the website.
What we expected: The app to run as 32-bit, load the interop, and display What we got: "Service Unavailable"All other web pages that were previously working displayed the same message, as did the Visual Studio 2008 version.The support page here describes the problem exactly, but tells us to do exactly what we did to resolve the problem (enable 32-bit mode).We've rolled back to 64-bit mode in IIS and deployed the Visual Studio 2008 version for now, but we really need to figure out how to make this app run and load the interop (there are also 32-bit Oracle DLLs that are referenced)Two questions:Why does the Visual Studio 2008 version work at all?? How do we get the Visual Studio 2010
