Slide.Show - Generate data.xml using ASP.NET
A while ago I talked about Slide.Show. Some one asked me how to dynamically look into a folder and create a slide show based on its contents. I suggested using an ASP.NET page that looks into the folder and generates a XML output that can be used by Slide.Show as a data source.
I’ve implemented a simple version that shows how to do it. Download it and change it as you wish.
Take a look at DataProvider.js where I have changed the Data.xml reference to Data.aspx file.
In the Data.aspx file I’ve deleted all the HTML output, and in the Page_Load event handler generated XML output.
Response.ClearContent();
Response.ContentType = “Application/xml”;
Response.Write(”{XML output}”);
Response.End();
I’ve included in the zip file only the required files to let the example work. It has only 1 image. I hope it will be useful to someone. 
Bruno, great Job. The only thing, i can’t figure out how to pass folder name from html page when, i’m creating slideshow control.
new SlideShow.Control(new SlideShow.XmlConfigProvider(foldName:????));
Thanx again.
You can do this:
create a dynamic generated configuration.xml (such as Configuration.aspx).
When creating the XMLConfigProvider, provide an url such as
new SlideShow.Control(new SlideShow.XmlConfigProvider({url:”Configuration.aspx?folder=XXX”}));
Then when you generate the Configuration.xml, you add an option to the DataProvider, where you put the url Data.aspx?folder=(parameter).
Thanx a lot. Let me try.
I got it to work with your help.
Thanx a lot again for your help.
Hello Bruno,

Well done to look in a folder and make the slide show.
But I’m looking to a solution that can use a sql server database image, write it on the xml file instead of in a folder, or write the image on a folder and then use this xml to read it.
Any sugestions?
Thank you
Let me see if I understand. You want to show a gallery using photos stored in a database?
You can generate an xml with the list of photos to display, where the url will be something like “http://website/loadPhoto.aspx?idPhoto=1234″
Hi, Bruno!
thanks for your tip…
i also want to show something like
http://website/loadPhoto.aspx?idPhoto=1234 which will generate an XML
any help on that will be greatly appreciated, thanx
In my example http://website/loadPhoto.aspx?idPhoto=1234 would not generate an XML, it would load a single image stored in the database.
The generation of a XML with the list of images is the original example that I posted.
Maybe I am not quite understanding your question. If you explain it again, I’ll be glad to help you.
Hey Bruno,
How do i pass the config file as a string variable instead of a string constant.
i would like to do the following
string urlString = “./ConfigFiles/Config1.xml”
new SlideShow.Control(new SlideShow.XmlConfigProvider({url: urlString }));
the above does not work.
In their website Vertigo use
)
new SlideShow.Control(new SlideShow.XmlConfigProvider({ url: “/SlideShow/Main/Configuration.xml” }));
In the code you’ve written there’s a missing ; in the first line (don’t know if was only here
If the code you have shown doesn’t work, try an absolute URL starting at the website root, like they did.
