AJAX :: Slideshow Extender Add_slideChanging Event?
Jan 6, 2010
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?

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 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...

Microsoft JScript runtime error: Sys.InvalidOperationException: Can't add a handler for the error event using this method. Please set the window.onerror property instead.
in localhost i ignore this Error and Slideshow Extender works correct.
but when i publish the site I have JScript Error and Slideshow Extender not be loaded.

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 read so many post which say if i need to catch the button event on the modal popup extender, i need to use javascript. But when it comes to my requirement I get confused.
I open a data entry form which contains several textboxes, drop down lists, validator controls and 3 buttons (viz. SAVE, SAVE & CONTINUE and CANCEL) on the modal popup. The requirement is that :
1. When the SAVE button is clicked the data in the different controls must be inserted into the database and the modal Popup must disappear.
2. When SAVE & CONTINUE button is clicked the data in the controls must be inserted into the database and the modal popup must be ready for the other with clear controls.
3. When CANCEL button is clicked the modal popup must simply be disappear.

I have a modalpopup extender attached to a button. That is to say the button is the targetcontrol id of the modalpopupsxtender. I would still like the onclick event of that button to work because only the onclient click event is working. How can i go about this.

So I have a button on form that is supposed to execute some code-behind on a click event. To this button I also connected a Modal Popup Extender, which once you click OK, it goes away. What doesn't happen (and it should) is btnSendContactForm_Click never gets called.
Using the OnOkScript didn't help me either. I have tried setting the OnOkScript property of the extender, by calling a javascript that simulates the button click on the send button, but that only re-calls the modal pop extender, and a never-ending loop results everytime you click OK.
<!-- Send Button, Extender, and Pop Up Panel -->

I'm new to Ajax and use MS Visual Web Developer 2008 Express edition with VB and SQL Server Express.
I have a number of photos stored in individual folders and wish to use the Slideshow extender to display all images in a selected folder.
I've set up a small test slideshow which is similar to the Ajax Video tutorial but cannot get autoplay to work.
The page displayed show the "Play button" and the first image in my set of photos.
I've pasted my code below.
Also as I'm new to this I don't understand Namespace - Do I just replace this with my website URL?

I wonder if it is possible to have a clickevent for the SlideShow control. In this case I am now showing 2 images.
Is it possible in any way have a clickevent or to handle a click on the images that is showing to open up a browser with a URL like www.google.com ?
I beleive the Click event then should be in the Image Control in somehow ?

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.

I'd like to create a slideshow that goes through 4 pictures with some text that pops up on to each picture. An example of this is here - [URL]
I think this is using AJAX slideshow and animation? where I can find a tutorial to do this? I've not been able to find one that mixes images and text in this way.

I'm using the slideshow extender, however the images are not a standard size. The images are user supplied, and they are often displayed full size, so I can't standardize them. I need a way to resize them on the fly, and have them look good.
I've been working on this slide show off and on for some time. I've had many false starts, finding out after putting in quite a bit of time and work that there is just one thing or another that I cant't get to work. I'm hoping this ajax extender will be the answer. It won't be if I can't rezise the images.
what the extender can use as image sources? I know it can use an image on the hard drive, which is where my images are, but then I have the size problem. I tried using a webpage that uses a third party control to resizde the image, but that didn't work. I'm looking at this site: [URL] for resizing the images, can the output be used by the extender?

I use the BetterImage Control [URL] to display my images. It allows me to add copyright text to the image and I can set maximum width and maximum height and have the image display without stretching. They have their own slideshow, but the documentation is very limited and I think it displays everything in the specified folder. I need to create slideshows on the fly.
I want to use the ajax slideshow extender, but I need to resize the images on the fly, and add the copyright text. Is there a way to use the slideshow extender with the Better Image Control? I'm going to look into adding the copyright text and do the resizing myself, but I'd rather not have to.
