I recently upgraded from VS2005 to VS2008. I did a full install of VS2008, then opened my existing project in it. This launched the conversion wizard which successfully converted my VS2005 project to VS2008 and it opened in VS2008 owever, when I first tried to build the solution in VS2008, I got an error on a page defining a web service saying
View 6 RepliesI mean can I do something like this:
[Code]....
and then implement it the same way as below
List<String> GetEmployees(String EmployeeId, String DepartmentID= "00")
{
}
I tried this, but it didn't work. Its always expecting DepartmentID when I tried to use invoke 'GetEmployees' using service reference.

I want to define Minimum and Maximum values in slider control. In slider control examples there is only one value in slider as in [URL]
View 1 RepliesI am working on a project which creates controls dynamically for a form in the page_load event, loads in their current values from the database and saves their values (using FindControl) when the user clicks the continue button. When I added a control statically in the .aspx page and followed their same procedure of loading the value in the page load and saving it on the button press I found that the value would not save correctly. It seems that it wouldn't save because the click event fires after the page_load, so the page_load of the post back reverted the value and the user entered value was not saved.
The strange thing is that by changing the control to be dynamically created just as all the other controls on the page and keeping the loading and saving the same it now works. Even though the page load still creates the control with the old database value. It seems like a very fundamental asp .net feature here but i'm just unclear as to what is going on. I suspect it is to do with the timing of creation and maybe when the view state kicks in.
i got a this exception when i calling my web service in producction server.i already test the web service in server side and this don't have problemasbut when i calling the web service in the development site this throw a

I have the following problem with a slideshow in Ajax. Hope I have put it in the right Ajax forum. Some info: I do use MS Access and in the 'autos table' i do have the following fields:
field 1: nummer (text field) - this is the name of the image
field 2: cat (integer) - this is the category of the cars
field 3: naam (text field) - this is the name of the car
field 4: model (text field - this is the model of the car
In my masterpage i do have a menu where you can make the choice of a certain category of cars. This is done by a call to: slideshow.aspx?cat=100 In Slideshow.aspx a panel is setup and also buttons to manipulate the found images. Also the AjaxToolkit:Slideshowextender is defined as follows:
<ajaxToolkit:SlideShowExtender ID="SlideShowExtender1" runat="server"
TargetControlID="Image1"
SlideShowServicePath="slideservice.asmx"
SlideShowServiceMethod="Getslides"
AutoPlay="true"
ImageTitleLabelID="Name"
ImageDescriptionLabelID="Desc"
NextButtonID="NextButton"
PlayButtonID="PlayButton"
PlayButtonText="Play"
StopButtonText="Stop"
PreviousButtonID="PrevButton"
PlayInterval="4000"
Loop="true"
ContextKey="catid" />
As you can see the contactkey is also defined.
Inside the codebehind of slideshow.aspx.vb their is a sub defined:
Partial Class Slideshow
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
SlideShowExtender1.ContextKey = Request.QueryString("catid")
End Sub
End Class
The call from slideshow.aspx is to a slideservice.asmx which contains:
<%@ WebService Language="VB" CodeBehind="~/App_Code/SlideService.vb" %>
Here we call slideservice.vb.
The coding of the slideservice.vb file is:

When i run the code i will get an exception error and when following the code in debug mode i do see that inside the first loop in FOR i = 0 to photocounter - 1 : The first loop gets the right info from the database inside Myslide(1) fields. Going into the second loop i will get after dim name as string .....
the program goes to catch x as exception. I did see that number was found correctly during the previuous line. During an other debug session i noticed that the Parameter.item has the following error (which I do not understand), saying: Overload resolution failed because no accessible 'Item´ accepts this number of arguments.
i use script manager and i do what ever the tuterials say for adding ajax toolkit .

I 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 + '"}',

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?

I developed a web service in VS2010 on my local machine, wrote a consumer of it also locally, and that all works.
I copied the dll and the asmx file to our server, and I am getting an error when I try to invoke it from a browser (also still on the server machine) to make sure it correctly exposes its web methods, but it is not, it is saying "Could not create type 'Service'". That error comes from this line:
Line 1: <%@ WebService Language="C#" CodeBehind="~/App_Code/WarrantyDuplicate.cs" Class="Service" %>
There other web services in the same folder on the server that all work fine so I don't believe it's an IIS setup thing.
This is my first web service in C# and when I created it in VS I did think it odd that the code behind file went into App_Code (as you can see from the line in the asmx file) and is just named dot-cs rather than asmx-dot-cs. But since it worked fine locally, I wasn't sure that mattered.
I am keep getting an error that "Service Error : wbsTest failed" where wbsTest is my webservice.
The error comes up frequently enough for the user - normally reproducible within a minute or so of working with an application.
A bit of background: An user is a remote user accessing application hosted on our servers over https. He is software firewalled and his connection isn't the fastest but it is responsive enough. When errors do not present themselves, page loads are fairly quick.
I 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.

I have a long-running WCF service that I need to call, but I would like to do is to open modal window (modal popup extender) that simply shows progress and stops the user from interacting on the page until the service returns. What I was trying to do was the following:
1. Click button to activate the process which calls a method in my code-behind.
2. This method opens my modal panel with some pretty animation.
3. I call my WCF service asychronously so that the UI will refresh.
4. Service ends which calls my delegate I setup.
5. My delegate method would then refresh the page with results, and dismiss the model popup.
I have a WCF service returning JSON to jQuery ajax calls and presenting the results on an ASPX page. When the page is NOT under SSL, the ajax calls work perfectly. When the page IS under SSL, the calls fail. I understand that this behavior must be due to the Same Origin Policy (SOP).
So, how do I setup my WCF service to accept calls from an SSL-secured page? Does the WCF service also need to be secured? If so, how do I do this?
I have site that I need to have a vendor send an Http Post to us, using querystring parameters, then I have to look up some data and return a few results and parameters back to them. Can this be done using CLASSIC ASP? I ask this because I am still in a learning phase with .NET and have limited resources available to set up a web service.
View 2 RepliesI 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.

How can I correct this issue so that I am able to call **loadDBData()** without that 500 error?
I am calling an AJAX Enabled WCF Service from jscript code and I'd like to bind the results to a very simple template. I get the results by calling the service via its jscript proxy:

In the OnComplete function the DataView is created:

The template which the data is bound to is really simple.
[Code]....
The XML response from the service is something like:
[Code]....
I get an error saying: 'Name' is undefined. I tried to bind Person.Name, ArrayOfPerson.Person.Name and several permutations without any luck. I'm sure I've been missing something here, and there should be an obvious answer.
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 have a text box and ajax autocomplete control extender in my Master Page that it is not working at all. When I type some characters on the text box it doesn't trigger the autocomplete. I have a web service that contains the function code. I est my code on a single Web Page (No Master Page) and it works perfectly. Also, it works fine if I include the text box and the extender on the Content Page instead of on the Master Page. It is important to keep the text box in the Master Page for me. I am using Visual Studio 2008 and ASP 3.5. MASTER PAGE.
