I'll start off by stating that I've read numerous posts with the same or similar errors but haven't found anything to solve my issue. I'm getting a lengthy error message:
Sys.Net.WebServiceFailedException. The server method'GetSlides' failed witht he following error: <html>

I appreciate any insight. See inserted code.

I've been scratching my head for what seems like ages. I'm sure its really simple to fix but I can't see it.
I have a class in App_Code that uses a bit of Linq.
var siteMap = SiteMapWrapper.BuildSiteMap(true);
var currentTopLevelParent = siteMap.Single(s => s.IsActive);
if (currentTopLevelParent != null)
I've developed this locally and all works fine. When I transfer to IIS hosting the same class fails to compile. I receive:
does not contain a definition for 'Single' and no extension method 'Single' accepting a first argument of type 'SiteMapWrapper' could be found (are you missing a using directive or an assembly reference?)
I confirmed that the virtual dir is running .NET 2.0 as it should. I also confirmed that the correct assemblies are being loaded in the web.config.

I am using SlideHowExtender in MVC application. It is not working. I have put the same code in simple .aspx page it is working properly in same application.

I'm using Visual Studio 2010.
Are there any step by step tutorials on how to use the SlideSHowExtender to create a slideshow?
I have had a look before posting but couldn't find any step by step info.
Each time I try to drag the SlideShowExtender to a web form I get a round black circle with a black line through the middle, in other words it won't let me use it and I must be trying to use this control incorrectly.
This was programmer error - a problem with my SQL. I am populating a slideshow extender control successfully from a list of images maintain din a MySQL database. I have created a "back" button that executes the following javascript:
[Code]....
This correctly goes back to my web service method that fetches rows from my database. I issue an "order by" in the SQL to sort the rows returned in descending tiome order and have verified that they populate the slide array in that order. However, when the page renders, the slideshow appears to play them in almost a random order. Is there any trick to getting images in a slideshow array to play in a particular order?

Recently I had to create a slideshow using the AJAX SlideShowExtender. One of the requirements was to have the images show up in a random order so visitors won't see the same slides over and over again. To do this I added some code to the GetSlides() function to reorder the slide array randomly. Here's the code:
[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
public static AjaxControlToolkit.Slide[] GetSlides()
{
AjaxControlToolkit.Slide[] mySlide = new AjaxControlToolkit.Slide[]
[Code]....
I'm using the slide show extender and want to combine it with some effects (e.g. fadeout of old picture / fadeIn new picture on picture change).
How do I do this? Can I combine the SlideshowExtender with the AnimationExtender control?
I have been struggled for a day without success. Also I am not sure is this possible, since I am not too familiar with Javascript. let me know is there a way to fix my problem. Here is my problem:
What I have is a datalist and at each row it contain an UpdatePanel and inside the UpdatePanel there are a button, a slideShowExtender with related controls and a hiddenField. The hiddenField stored a second contextKey value. At page load time the default contextkey already assigned to the slideShowExtender. What I want to achieve is when user clicked the button the slideShowExtender will switch the Contextkey with the hiddenField value so that the SlideShowExtender will display a new set of images.
So far I can make everything work as I want with server side function, which executed when the button onclick. However this will generate a whole page post back, which I want to avoid. So I was thinking of using client side Javascript to do the contextkey assign and then update the updatePanel, but I am not too familiar with Javascript so I can't get it working :(

View 1 RepliesI am using SlideShowExtender and I am using a Slideservice webservice located also in root folder. It works fine. My image folder is in ROOT FOLDER. But I have member webpage folders and a general web pages folder. Now, when I click on webpages of any of these folders, the slideshowextender stops working because it looks for my IMAGE folder in those Webpage Folders. I know this happens because I can see it trying to download the image from that URL which DOESNT EXIST(looking for my image folder in webpage folders).
How do I make a relative URL for the images so that the slideshowextender still POINTS to the ROOT FOLDER of images and displays images at all times.
I cannot make the slideshowextender work when I am logged into the system.

'm using the AutoCompleteExtender from the AJAX control toolkit on my aspx page - I have it wired up to a WCF service that is returning a string array and everything works happily.
If I change my service definition to include a demand for the caller to be authenticated, like so:
<OperationContract(), PrincipalPermission(SecurityAction.Demand, Authenticated:=True)> _Public Function GetLookupValues(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String()
Then the autocomplete extender stops working, and I get an authentication error in the service. The service is set up to use ASPNetCompatibility mode, and I was hoping that the extender would pass the authentication credentials for my logged in user - does anyone know how to make this work?
