AJAX :: Call Viewstate In AutoCompleteExtender's GetAutoCompletionList Method?
Jan 4, 2011I am using VS 2008. I am using Ajax Autocomplete extender to populate a textbox. usually there is a webservice method which populates data into the autocompletion list... but in my case, the data is coming via an instance method...
At the time of doing the autocomplete, the autocomplete calls the method, the data is getting lost in the page postback..My situation is such that I cannot use a static method to get data from database, since there is already a public instance method.I am using the technique of calling GetAutocompletionList without using a WebService method.
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] GetAutoCompletionList(string prefixText, int count, string contextKey)
{
// want to use static viewstate here ..
AJAX :: Use AutoCompleteExtender Control Without Web Service Calls?
Apr 17, 2010I am successful in using the AutoCompleteExtender control by make use of web serivces as the data source (ServiceMethod) to the extender control. My question is do we have any way in assining a code behind method as data source to this control.
removing the ServicePath url and assiging code behind method to ServiceMethod attribute will resolve the issue.
AJAX :: AutoCompleteExtender Not Working With WebMethod And No Web Service
Jul 18, 2012I tried your code for Autocomplete without Webservice and didn't work on my page. When I tried it on a new project it works fine but on my project it does not. I have other controls on the page but that shouldn't stop it from working right?

Sep 5, 2010I have created an autoextender & cannot seem to get it to work within my pages. So I'm missing something probably small yet important.
The webservice AutoComplete.asmx, when called by itself, does return data correctly.
The codebehind for AutoComplete.asmx is located in the App_Code folder.
AutoComplete.asmx and the page from which I am calling it are both located in the root folder.

AJAX :: Trying To Get AutoComplete To Call Web Service
Apr 26, 2010I'm going on my 3rd day trying to get my Ajax AutoComplete textbox to call my web method. Based on my google searches, I'm not alone. I suspect the problem has something to do with the ServicePath property on the extender, although I'm not sure. My web service is at the same level, on the same server as my test web page. I'm not sure exactly what should go into the ServicePath property, although I think I've tried every possibility. Below is my web service followed by my script.

Weird Project Specification - Web Service - AJAX?
Mar 25, 2010I have a project spec to build an online card game, and on a point it mentions:
"...the page should not post back to the server at any point; neither should the ASP.NET UpdatePanel control be used. Server communication should occur through webservice calls or similar."
I just asked a developer if it's possible to use AJAX without UpdatePanel, or/and use just a web service to prevent a page postback, and he said "the spec sounds a bit out of context".
Basically the application should provide a user interface and use Async postbacks (i.e. AJAX)...
Call An Ajax - Enabled WCF Service With JQuery?
Jan 28, 2011I 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
Call WCF Service Through Javascript - AJAX Or JQuery
Jan 13, 2011I 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.
AJAX :: Can Not Call Two Different Pagemethods With Two Service Methods
Oct 1, 2010I am using an AJAX dropdownlist control with two dropdownlist. Instead of using a webservice to populate the data, I used the pagemethod to populate. My problem is the second droplist won't populate. I get a server error, 500 in the droplist. The first droplist populates fine.
BUT here's the real kicker. If I reverse the order of the public static function such that GetHelloList2 comes BEFORE GetHelloList1 in the code, then the GetHelloList2 works ...... it just seems like it is only firing one pagemethod event and allowign only one.

AJAX :: ModalPopupExtender + Web Service Call Failed: 500?
Nov 17, 2010I know this is a pretty common issue as i have read a lot of posts from people with similar issues. However thus far what i have uncovered doesn't seem to help resolve my issue. I have used the ModalPopupExtender regular enough but this is my first time needing the Dynamic side of things. The code I have is very basic and generic at the minute..I have the following ASPX code in place:
[Code]....
Now just to say at this stage the Modal Dialog box pops up and closes 100%. So my ProductPopulate.asmx service at the moment for testing is just using the VS2010 default Web Service with a few changes that i will explain.
[Code]....
So the changes i have made to the default VS2010 webservice is from this article http://sandblogaspnet.blogspot.com/2009/07/working-with-modal-popup-extender.html
I changed the default HelloWorld method to static and also uncommented the following line
[Code]....
So this is as far as my code has gotten at the minute. The Modal Dialog pops up 100% and what i would expect to see within the dialog box would be the text "Sampling Control" from the DynamicContextKey. Instead what i get is the "Web Service call failed: 500" error. I have stripped everything back to basics as you can see.. but for some reason i am still getting this error. I have used Web Services before from time to time without any issues and i have used the ModalPopupExtender without any issues.. but i am left scratching my head as to what i am missing on putting the two together.
Also just to note, both ASMX and ASPX files are currently in the root of the web project to rule out any path issues. Also i am using the VS Web Service to preview and debug.

AJAX :: Call To Service To Fill In A DataView
Jan 1, 2010I'm just learning MS ajax and am having problems getting a relatively simple test to work. I'm attempting to call a web service (of the .asmx variety) to return a very simple 3-column table to render in a dataView in an .aspx page. I've successfully created a working service and can by stepping through the service code it's getting the data correctly. The problem I'm having is that it stops with an exception in MicrosoftAjaxDebug.js on this line:
[Code]....
where my user_table contains 3 columns: user_name, user_key, user_ID. Real simple.My test.aspx page to get this data looks like this:
[Code]....
One more thing, I'm a little confused between the two downloads I've found, "MicrosoftAjaxLibrary_Preview6.zip" and "AspNetAjaxLibraryBeta0911.zip". From what I can tell, the latter contains all the old Ajax toolkit gadgets as well as the MS Ajax scripts. Is the MS Ajax download just a refresh of the ajax scripts in the Asp.Net ajax library? I've installed and am using the preview 6 scripts for my website.
Jquery - Ajax Call For WCF Service Undefined Error
Feb 22, 2011I have this method in asp.net ajax enabled mvc service
[OperationContract]
public TestRun GetTestSuite(string testSuitName) {
TestRun testRun =
AdapterFactory.CreateTestRunAdapter().GetByTestSuiteName("testSuit");
return testRun;
}
Where TestRun is Created using entities framework against TestRun table. I am using following ajax method
function getTestSuite() {
$.ajax({
type: "POST",
url: "Services/TestRunService.svc/GetTestSuite",
data: '{"testSuitName" : "' + testSuiteName + '"}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
},
//If the call fails
error: function (xhr, textStatus, errorThrown) {
alert(errorThrown);
}
})
}
I get undefined error. If I return string from service it works. Do I need to change dataType: "json" to something else?
AJAX :: Invalid Web Service Call, Missing Value For Parameter?
Mar 2, 2010In a web page, I call a web service (located in the sub folder WebServices) with ajax asp.netHere my aspx code:
[Code]....
My web site uses integrated windows authentication and all works fine.However, my web service doesn't need authentication and in order to not have 2 requests (because of http code 401), I've allowed anonymous access on the WebServices folder. Doing this, I get the folowing error message when I call a web method: "Invalid web service call, missing value for parameter: user"When I look at my body request with Web Development Helper, I can see {"user":"toto"}. So, I don't understand why it's not working.Another weird thing: when I run Fiddler2 instead of Web Development Helper, every thing works fine. I turn off Fiddler2, and it doesn't work any more.

Jquery - Why 3 Extra HTTP Requests Are Done If You Use Ajax Call To A .net Web Service
Apr 4, 2011When I was reading the blog Using jQuery to Consume ASP.NET JSON Web Services
I have seen this argument:
"By using jQuery to call the web service directly, we've eliminated over 100 KB of JavaScript and three extra HTTP requests. "
Why does the ASP.NET AJAX call to a .NET Web-Service needs 3 extra HTTP requests? What are those requests? (I wonder how jQuery manages the call with lesser HTTP requests in this case).
VS 2013 - Call Web Service Function Within (Code Behind) Using AJAX On Page
Dec 4, 2014I am trying to call a web service function within my own ASP.net (code behind) using AJAX on the page.
Once i push the button to execute the JS/AJAX/codebehind - I got an error.
POST http://************/admin/Admin.aspx/getDBInformation 500 (Internal Server Error)
This is my code below that I am currently using:
Code:
<WebMethod> _
Public Shared Function getDBInformation() As String
loadDBData()
Return JsonConvert.SerializeObject(dbInfo, System.Xml.Formatting.Indented)
End Function
End Class
The code behind looks like this:
Code:
Imports System.DirectoryServices
Imports System.Security.Principal
Imports System.Net
Imports System.Drawing
Imports System.IO
Imports System.Data.SqlClient
Imports System.Web.Services
Imports Newtonsoft.Json
[Code] ......
How can I correct this issue so that I am able to call **loadDBData()** without that 500 error?
AJAX :: How To Avoid Cascading Dropdowns To Call Their Service Methods On Every Postback Of The Page
Feb 24, 2011I have three cascading dropdowns on my web page and they work fine. The issue I am facing is that there are other controls on the page which cause a postback and with each postback the cascading drop downs are being re-populated (service methods are called) which is becoming a performnace issue.
