AJAX :: Resize Images With The Slideshow?
Dec 1, 2010
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 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 ?

on another post i mentioned the problem but simplified it here! I am using ajax slideshow extender and getting images from my database
Datbase table file path example
/ ImageURL
/Members/matt//jeanette4.jpg
Code Behind
//here i open sql connection to database and retrieve images based on GUID of UserId which i add as sql parameter.//
// set the initial image
if (tblData.Rows.Count > 0)
{
imgShowImage.ImageUrl =tblData.Rows[0]["ImageUrl"].ToString();
imageLabel1.Text = tblData.Rows[0]["FirstName"].ToString();
}
}
}
[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
public static AjaxControlToolkit.Slide[] GetSlides()
{
AjaxControlToolkit.Slide[] slides = new AjaxControlToolkit.Slide[tblData.Rows.Count];
for (int i = 0; i < tblData.Rows.Count; i++)
{
DataRow dr = tblData.Rows[i];
slides[i] = new AjaxControlToolkit.Slide(
dr["ImageUrl"].ToString(),
dr["FirstName"].ToString(),
dr["LastName"].ToString());
}
return slides;
}
ASPX
Page shows the image
<asp:Image ID="imgShowImage" runat="server"
Height="300px" ImageAlign="Middle" />
This all works fine/ but when i set up the web config with Intelligencia.UrlRewriter code the slideshow images do not appear but the page gets divirted correctly
<rewriter>
<rewrite url="~/Matt" to="~/MembersClub/PublicProfile.aspx?Id=a8742959-aa5e-4830-9fc1-94f1b3d0bc41"/>
</rewriter>
The images are stored in a file directory named "Members".

I have images at the head of the page in an iframe and in the main center page. The image at the head flows over the social icons and the images at the center page resizing drops below and pushes the other image down. I just want the images to resize when the browser is being resized. Go to [URL] .... and you'll see what I mean.

In my Web page,I have a Div section with height=302PX and width=302PX.
In another page,I had a File Upload control. When we will upload the image,then the image will be displayed in that Div section.
1.When the image is large,it should be re-size and display in that particular Div section completely.
For Eg:The image size like 350PX*350PX and 1024PX*1024PX, it should be re-size to Div Section size has 302PX*302PX.
2.When the image is Small,it shouldn't be re-size and display in that particular Div section completely.
For Eg:The image size like 50PX*50PX,100PX*100PX and 302PX*302PX ,it shouldn't be re-size and display in that Div section.
For Eg:The image size like 15PX*15PX these will appear very small.But When uploading the file these images also should displayed completely with as it is in that Div section.But the image will displayed neatly.
3.If there are any tools for these type of conditions using ASP.Net.

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'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 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.
[Code]....
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.

I'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?
