The Slideshow isnt looping, however, it appears that the page is trying to refresh itself for each loop interval (I can see this at the bottom: downloading ...)
This should work because Im basically used the same code thats in the demo, minus the labels and buttons, and modified the web.config to be identical as well.

Here is the web.config:

I have found all kinds of tutorials on the web showing how to implement the AJAX slideshow extender, but can't get them to work. All I want to do is put a simple slideshow on a master page. I want to use a code behind file for the c# (do not want the script on the page itself.
I ran into a couple of problems with the samples on the web. Specifically when I try to add System.Web.Services.WebMethod and System.Web.Script.Services.ScriptMethod - VS 2010 doesn't know what the "WebMethod" or the "ScriptMethod" are. Further, VS2010 express keeps telling me "{" expected - on the line AjaxControlToolkit.Slide[] slides = new AjaxControlToolkit.Slide[5];
Every tutorial on the web seems to be for ASP.net 2.0 - and is at least 2 years old. Is there an easier way in ASP.Net 4 to implement the slideshow control? I am new to c# in general, so if someone could provide a simple cs codebehind file - and the code on the aspx page, that would be great. I understand more than I can write.

I'm using the Slideshow extender and have a vexing problem that I can't see to solve. The slidehow itself works fine, but I am trying to get the value of the ImageDescriptionLabelID into a javascript variable when the slide changes. Using this code in a javascript function:
[Code]....
It appears that the add_slideChanging event fires BEFORE the image (and accompanying label) change. Is there an event that occurs AFTER the image changes?If not, any ideas on how I can make the number I'm successfully passing in the lblDesc control available to javascript?

I have a slideshow extender, I will change the slideshow extender's contextkey value by a button click event. So that after button click the slideshow will display different set of image. Originally with postback everything work fine, but I don't want the whole page to refresh.
So I put the slideshow extender inside an updatepanel with triggers target the button click event. Now the whole page didn't refresh and the slideshow extender's contextkey value did change (same code as before) after button click event. However the image set on the slideshow didn't change.
I think I am missing some sort of slideshow extender reload or refresh call but I am not sure how to do this? I didn't see any related property with slideshow extender...

I am using a detailsview control in my form and I want to use the Ajax calendar extender control with some of the fields.
After I have connected the textboxes to the extender and when I click on them there is no calendar displayed.
If this makes any difference I am containing the detailsview in a regular panel control which I make visible through a button click.
Here is the code for the detailsview:

I have this slideshow extender that works perfectly with hard coded images in the page method. However as soon as I try to make the page method get its images from the database it stops working; no images are returned.
I have tried to declare the datatable that the pagemethod uses both inside the pagemethod and in the on_load event. When in the last case I test the datatable contents by hooking it up to a gridview, it shows that it does get its proper data.
Declaring this dataTable as a private static dataTable, outside the page_load, to make it accessible in the page method (like in this --- post http://forums.asp.net/p/1115257/1726736.aspx---) also does not work.
So the page method with hard coded images works and also the query to the database works!

My slideshow extender work perfectly fine, but I want to retrieve the current display picture's information on the server side.
So I added a normal asp button on the same page as the slideshow extender. When button clicked, it fire off a server side function. In the function I grabbed the SlideShow's name label, description label or the Image, but none of them contain any current information of the picture displayed at slideshow extender.
Is there another way to obtain the slideshow extender current state? Or am are those name, description label text value should be updated?

I need to set up the slide show based on a querystring parameter. I thought I had this figured out, but I clearly don't understand something about how the webservice works. I have this in the .aspx page:
<asp:Button ID="btnPrev" runat="server" Text="Prev" />
<asp:Button ID="btnPlay" runat="server" Text="Play" />
<asp:Button ID="btnNext" runat="server" Text="Next" />
<asp:Label ID="lblDesc" runat="server" />
<cc1:SlideShowExtender ID="SlideShowExtender1" runat="server" BehaviorID="SSBehaviorID"
TargetControlID="tstSlides"
AutoPlay="true"
ImageDescriptionLabelID="lblDesc"
NextButtonID="btnNext"
PreviousButtonID="btnPrev"
PlayButtonID="btnPlay"
PlayButtonText="Play"
StopButtonText="Stop"
Loop="true" >
</cc1:SlideShowExtender>
<asp:Image ID="tstSlides" runat="server" height="300px" Width="300px" />
And this in the code behind:.........................

I've followed 2 different guide to implement the autosuggest feature on a textbox and it doesn't seem to work.
I followed this guide mainly:

When I type more than 3 characters into the textbox, nothing happens.
The bulk of what I've pasted below was copied and pasted from the guide I was following, so I'm not sure where I could have gone wrong.

I just tried a simple page with a collapsible panel extender, following the tutorial video at asp.net/ajax/videos. When clicking on the header panel, nothing happens. I have gone through countless posts looking for the answer, I have not found a solution. When viewing the page using IE, it shows a page error: Object expected. The cpe does not work in any browser; it does not work on my local machine or production server. As far as I know, the Ajax Control Toolkit was installed correctly; the .dll is in the bin folder. see this link for the page in question: [URL] Below is the code for the page:
