AJAX :: Implement Slideshow Extender With A Code Behind File?
Feb 24, 2011
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.
what i am trying to achieve is a single image control with slideshow extender attached which when of the category option buttons are pressed the SlideService goes get the images for that category from the image folder sub folders and starts to display them i have got the code to work as to, the point that i have to hardcode the images sub folders path in to the webmethod - but i want the image folder name to be passed as a parameter when the webmethod GetSlides is called - the code i have so far is From the aspx page - (the category name will be a string retrieved from the button text when clicked
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.
I'm using ajax slideshow extender for a slideshow. How do I use an imagebutton to play/pause slideshow. I would have to change the imageurl with the corresponding action...
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...
when I run my site that used Slideshow Extender, i get this Error:
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:
I want to slideshow images from database, four images at a time.The images should slide after 2 seconds and slides should scroll from right to left.During this left most image should disappear and all remaining images should move to left,covering leftmost image. At the place of rightmost image a new image from database should be picked up.
i need to make my Table to do some animation on LoadComplete Event (CodeBehind) and i choose Ajax Control Toolkit to do it. but i don't know how to do it in Code behind.i regularly use Ajax Control Toolkit directly in ASPx page not in aspx.vb page.
i need to set the textbox associate with the calendar extender to read only and i dont want the calendar to show when i click on the textbox.take notice i had the textbox inside a formview and i need to set it from the code behind.
i have created an ajax modal popup extender and i want to be able to grab the values in the textboxes that are on the panel. how do i accomplish this from code behind:
[Code]....
once i have the value i need to perform a stored proc and isnert into the database. i have this part sorted but not sure how to grab the values initially.
I have a modal popup extender and I try to setup the image url, title and text in code behind but all I get is the popup, with no text, title or image and can't see why. All I see is the OOK button near the top of the dialog box. This is what I have:
I have a web page that I am trying to use modal popup extender with aLink button as trigger (Code Below). When I execute the code and click on the link button (TargetId) the parameter for graying out the page below the popup works but I do not see the ModalPopup panel
