Hi there,
I have copied the slideshow example into my own project.
So I now have a folder called SlideShow. I copied the images folder over and also SlideShow.aspx,slide.cs,slideshowbehaviour.js,slideshowdesigner.cs,slideshowextender.cs
When I try opening the page I get a large popup box displaying the following error message.
--------
Windows Internet Explorer
--------
The server method 'GetSlides' failed with the following error: <html>

Thanks for your help.

In your web.config have you uncommented the json serialization section? You will need to add a real converter in that section. This, Acme.SubAcme.ConvertMeTypeConverter, is just a "howto" placeholder.

Yip I have uncommented that line. I copied over the webconfig from the example site into my own site.
This is the webconfig. I am really new to .NET & AJAX so I am not sure how what I need to do to add a real converter in that section
Thanks for your help

Shane,
You can use the web.config from the toolkit sample website for your stuff. We have it commented out in that file. Looks like you do not need to worry about Converters and you can safely keep it commented out. If you need more information you can take a look at some documentation onconverters.

Hi again,
Sorrry if im sounding very simple here but I don't understand :( I have searched through the example site and there is only 1 reference toAcme.SubAcme.ConvertMeTypeConverter which is the web.config which is the same as mine.
However I get this popup.
Do I need to add this into the page load event?
// Get the Web application configuration.
System.Configuration.Configuration configuration =
WebConfigurationManager.OpenWebConfiguration("/aspnetTest");// Get the external JSON section.
ScriptingJsonSerializationSection jsonSection =
(ScriptingJsonSerializationSection)configuration.GetSection(
"system.web.extensions/scripting/webServices/jsonSerialization");//Get the converters collection.
ConvertersCollection converters =
jsonSection.Converters;if ((converters != null) && converters.Count > 0)
{
// Get the first registered converter.
Converter converterElement = converters[0];
}
You should just comment out that section. You do not need it if you are not dealing with Converters. Acme.SubAcme.ConvertMeTypeConverter is just a dummy placeholder that is actually commented out in the atlas web.config and in our sample website web.config as well. It is a "how-to" add a converters section to your web.config file sample. We recommend that you reuse the sample website web.config for starters.
Thank-you I do feel silly now.
This brings me to my next question so I think I will start a new thread.
Thanks again.
Shane
