How to display images stored in SQL Server DB using SlideShowExtender
Heres my my Web Page:
[Code]....
I need to create a thumbnail solution in order to display pictures of products.
There can be more than 1 thumbnail per product and I need a way to enlarge the image as well. The thumbnails will be displayed in atleast 3 or 4 pages across the system and I need the ability to delete them as well. For version 2 of the software (knowing PM's it may be thrown into Version 1), I think I will need to be able to enhance this feature to allow movie clips so that's something I need to keep in mind. The images will be stored in the DB so I can sort the code to retrieve them but I'm originally a windows programmer and this is my first major ASP.NET project and also my first attempt at C#.
I have ran into an issue where I have to use ASP.NET to do a Thumbnail of images uploaded since the hosting company does not have any of the required ASP Classic 3rd party utilities that I can use. I have played around with several different Upload scripts before I found a tutorial on using: Uploadify (Love this script) with ASP.NET. [URL] What I am needing to do with the script is to create Thumbnails of the images that are uploaded, and when I try to do so, I get an IO Error. I was informed that I would have to create a Web Application instead of the Web Site as the web application would give me the default.aspx.designer.cs file for setting the FileUpload control as Public to be used in the upload.ashx file. But after doing that it basically breaks the code. What works in the Web Site, does not seem to want to work in the Web Application. What I would like from the .NET community is some help in making the Uploadify script to create Thumbnails. The script for the Thumbnails that I am using (or trying to use) is here

- In have a website where users can upload their photo and along with their profile.- I store the photo as binary data in database.- Using ASP.NET MVC 2.0 FileContent option, I display Photo back in the browser, when user view his/her profile detailsQuestion: Currently I am showing image as-is and not restricting width/height, so that users see exactly whatever image they uploaded as-is without distortion. However I want to do like every other website: Show only smaller image alwayswith fixed size and allow user to click on it to pop-up and show original image as-is in pop-up.NOTE: I can do this simply restricting width and height to fixed limits but still show original image. But in this case image is distorted as it was not originally designed for this dimension.This very basic question and I am seeing many options, including some libraries. But don't know what is best way to do this using ASP.NET MVC 2.0
View 1 RepliesI have a website that enable the user to upload pics to server (uploaded pics sizes are 300x400 and approximately 270kb). In my app. I am having another page that lists the pics and I am using there an image control for that purpose. The Image control sizes are 80px width, 60px height. My question is how can I improve the download speed by minimizing the images ? Do I have to create a thumbnail for each picture the user upload?

View 7 RepliesWe are planning to introduce Load balancing in our server environment. Our site has lots of thumbnails (Thumbimages) to get displayed on the website. As all the images should be there under Web directory to get displayed on web site, do I need to maintain these TNs in all the servers? Is there any other way to accomplish this?

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!
A page using SlideShowExtender works fine with IE8 and FF, but not IE9.I am wondering if anyone has made SlideShowExtender work for IE9.

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[]

My task is to display gallery for a particular school...i'm displaying thumbnails in a datalist...And when i mouse over on a particular thumbnail it must display the actual image in a panel....All the thumbnails and images are stored in the database(in byte format)...
Problem is when i'm executing its displaying blank image..
[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 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;

The Bold part of the above code is the problem...

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 am having trouble with my .asmx. I keep getting the error:

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.
