I would like to use the ajax slideshow extender and getting the Image Url stored in a databaseso far my webserivice look like this..but I think im making a mistake somewhere..its not working
<WebMethod()> _
Public Function GetSlides() As AjaxControlToolkit.Slide()
Dim Connection As SqlConnection
[code]...
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:.........................
how can we have the ajax slide show which take the image path from database, instead of define the image path static in service method.
View 1 RepliesI've watched the Slideshow videos and created a number of examples that run fine. The code I've attached at the bottom is the smallest one, but instead of hard coding the image locations, I would like to select the slides from either of the following statements, which return the top 5 images selected randomly from our floorplans database.
<asp:AccessDataSource id="AccessDataSource1" runat="server" DataFile="../fpdb/J3_2005.mdb" SelectCommand="SELECT TOP 5 [Elev_Pimage] FROM [PLANS_Active] ORDER BY RND(INT(NOW*[SF_Total])-NOW*[SF_Total])" />
or,
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:J3_2005Slideshow %>" ProviderName="<%$ ConnectionStrings:J3_2005Slideshow.ProviderName %>" SelectCommand="SELECT TOP 5 [Elev_Pimage] FROM [PLANS_Active] ORDER
BY RND(INT(NOW*[SF_Total])-NOW*[SF_Total])" />

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!
I'm using Webservice which will return the data from the database through datatable and I'll convert the datatable into byte array. In front end, I'll reconvert the bytearray to datatable and used ajaxloader to display it in the form.. It is dynamic loading. So, for each click, it is taking 10 seconds to retreive the data regardless of the size of the data. So, I used static datatable and I've loaded all data in that datatable in page load event. But, no reaction. It is taking only same time. Even, there is no data to retreive, the ajax loader is going on loading for 10 seconds. Problem is with Ajax or my webservice?? Plz, tell me some other idea??!!

how to slideshow images from database without using javascript in asp.net.
View 4 Replieshow can i develop a slideshow of images coming from database?
View 1 RepliesI was wondering if anyone knows a jQuery library that can suit my needs:
I want a slideshow of album covers which are retrieved dynamically from the database. I want to display 4 album covers at a time. I want there to be a next button so the the slideshow can continue. Here is what I cant find any librarys for. When I click the next button, I dont want to show another 4 different covers, i want it to move along by 1 album cover,
So say I had covers 1 , 2 , 3 , 4
When i click next i want to display 2 , 3 , 4 , 5.
Finally, I want the show to be able to repeat so at the end it starts at one again.
So say I only had 5 covers 1 , 2 , 3 , 4 , 5
when I click next while showing 2 , 3 , 4 , 5 I want 3 , 4 , 5 , 1 displayed.
I want upload image in database and display image in slide show on website  without gallery and button using gridview.
View 1 RepliesI'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 ?

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.
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:

An Ajax Toolkit SlideShow used to work in .NET 2.0. After being upgraded to 3.5 the same slideshow stops working as before. It always pops up "Object reference not set to an instance of an object.". Different rewrites cause different errors at embedded Jscript level that cannot be fixed. I have added the AjaxToolkit.dll 3.5 under bin folder and placed its items in the VS2008 toolkit.
View 5 RepliesI'm using Visual Web Developer 2008 Express Edition, coding in C#. I think that the framework that I am aiming for is 2.0.
I am working on some old projects here where I work. However, I do not have access, nor do I know what the original programmer used to write this code.
The following code gives me an error:
[Code]....
(note that SlideList is an ArrayList that is being assigned to a DataSource. Also, this code is found inside a function named "CreateFeaturedSlideShow", which is called by the function "Page_Load" in "default.aspx.cs")
When I try to compile the project I get this error code: "The type or namespace name 'slideShow' could not be found (are you missing a using directive or an assembly reference?)"
When I comment out the code, the project compiles. However, when I try to run it, I get another error message: "Only one of AdvertisementFile, DataSource, or DataSourceID properties can be set on AdRotator 'AdRotator1'. "
From examing the rest of the code, it seems like this part of the project is populating a database with advertisement data, and selecting an ad at random, and keeping track of various statistics.
My problem is that I am having difficulty locating anything that will give me a slideShow namespace. The top result seems to be the SlideShow Extender, but after adding this toolkit to my toolbox nothing changed, which leads me to believe that I have something else.
Does anybody know where I can find this 'slideShow' that is referred to in the code?
i am working on ajax slideshow extender.
1) implement transformations between slide to slide.
2) and the direction means orientation in changing of slides.
I have the following problem with a slideshow in Ajax. Hope I have put it in the right Ajax forum. Some info: I do use MS Access and in the 'autos table' i do have the following fields:
field 1: nummer (text field) - this is the name of the image
field 2: cat (integer) - this is the category of the cars
field 3: naam (text field) - this is the name of the car
field 4: model (text field - this is the model of the car
In my masterpage i do have a menu where you can make the choice of a certain category of cars. This is done by a call to: slideshow.aspx?cat=100 In Slideshow.aspx a panel is setup and also buttons to manipulate the found images. Also the AjaxToolkit:Slideshowextender is defined as follows:
<ajaxToolkit:SlideShowExtender ID="SlideShowExtender1" runat="server"
TargetControlID="Image1"
SlideShowServicePath="slideservice.asmx"
SlideShowServiceMethod="Getslides"
AutoPlay="true"
ImageTitleLabelID="Name"
ImageDescriptionLabelID="Desc"
NextButtonID="NextButton"
PlayButtonID="PlayButton"
PlayButtonText="Play"
StopButtonText="Stop"
PreviousButtonID="PrevButton"
PlayInterval="4000"
Loop="true"
ContextKey="catid" />
As you can see the contactkey is also defined.
Inside the codebehind of slideshow.aspx.vb their is a sub defined:
Partial Class Slideshow
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
SlideShowExtender1.ContextKey = Request.QueryString("catid")
End Sub
End Class
The call from slideshow.aspx is to a slideservice.asmx which contains:
<%@ WebService Language="VB" CodeBehind="~/App_Code/SlideService.vb" %>
Here we call slideservice.vb.
The coding of the slideservice.vb file is:

End Class
When i run the code i will get an exception error and when following the code in debug mode i do see that inside the first loop in FOR i = 0 to photocounter - 1 : The first loop gets the right info from the database inside Myslide(1) fields. Going into the second loop i will get after dim name as string .....
the program goes to catch x as exception. I did see that number was found correctly during the previuous line. During an other debug session i noticed that the Parameter.item has the following error (which I do not understand), saying: Overload resolution failed because no accessible 'Item´ accepts this number of arguments.
