AJAX :: SlideShowExtender Default Image?
Dec 14, 2010
I keep on drawing this error:Sys.Net.WebServiceFailedException: The server method 'GetPhotos' failed with the following error: System.Data.SqlClient.SqlException-- The parameterized query '(@ImageAlbumGUID nvarchar(100))SELECT * FROM [Image] WHERE [Image' expects the parameter '@ImageAlbumGUID',which was not suppliedI understand how it is drawing it, When I skip creating an album It does not create an ID, so instead I would like to show a default image not from the db. I have been trying to figure out if @ImageAlbumGUID is nothing then the show image.

I am having trouble with my .asmx. I keep getting the error:
Sys.Net.WebServiceFailedException: The server method 'GetPhotos' failed with the following error: System.Data.SqlClient.SqlException-- The parameterized query '(@ImageAlbumGUID nvarchar(100))SELECT * FROM [Image] WHERE [Image' expects the parameter '@ImageAlbumGUID',
which was not supplied
I have my .asmx set up to display images if there is an album created from the db. If there is not an album created I would like to use a default picture. I tried setting the Image Url of the asp:Image to the image I want, but regardless I get this error.

I 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.

I am having problem Using AJAX SlideShowExtender Control to retrieve image from Databases with querystring which passes query to an ImageHandler.
all my images to display are stored in database and I can retrieve them from Database using Gridview and so on. but using AJAX SlideShowExtender Control to retrieve image from Databases is a problem.
for example this code in code behind;
[Code]....
The Bold part of the above code is the problem...

Actually this should pass the query to the ImageHandler.ashx class created in a folder Handlers in my Project.
the other two ...
[Code]....
slides shows perfectly because the Images are stored in the Filepath.
but I don't want to be storing my Images in a folder in my website but in database.
how to use AJAX SlideShowExtender Control to retrieve image from Databases?
whereby a querystring is passed to the Imagehandler that retrives image from database and resize them?

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 :(
Here is my current code:

i have a website which has a <IMG> and/or <asp:Image> in it.
The user has an option to upload an image. so if the user does upload an image it will be displayed in the stated controls above. but if they don't the control displays its alternative text or an "x" icon. can i just place a default image in it if there is no image reference to it to display?
