Can you access the XML file via IE?

I'm able to add a local version of the file to my project. But I really need it external so the config can be updated by a system manager without rebuilding. Got http to run but says it can't set credentials to access my site. I used Webclient.Credentials = new NetWorkCredentials(user, passwd) but got an exception that the property is not allowed.

Yes, like www.mysite.com/MyFile.xml

Are you able to include the XML file in your SL project?

I loaded the file up to my ftp site and still couldn't get a response on the async read. Does it have to be http?

Did you include the XML in your project? Make it relative path. You can't open files on the client that arne't included in the project.

Or Try a absolute path by putting the file on a server and accessing it via http://...

Am having the same problem as HSCODER. Any suggestions?

I've implemented the code exactly as above. It compiles correctly and runs. The problem is that the callback function never gets called. I've traced through in the debugger and watched the cl.DownloadStringAsync(uri) statement get executed. Immediately after that I am checking the cl.isBusy and it shows false (async download not still in progress). However, the callback function is never executed and there are no errors thrown at all. Anybody have any ideas on what I might be doing wrong? I am new to Silverlight, so I may be making an obvious mistake...

Here is my code:

Here's where I set everything up:

// Open doc using WebClient (must use this for Silverlight)

WebClient cl = new WebClient();

cl.DownloadStringCompleted += new DownloadStringCompletedEventHandler(cl_DownloadStringCompleted);

Uri uri =

new Uri(@"C:\Users\Aly\Desktop\Prototype3\Prototype3UI\Prototype3UI\ServerMonitorStatus.xml", UriKind.Absolute);

cl.DownloadStringAsync(uri);

bool status = true;

status = cl.IsBusy;

while (cl.IsBusy)

{

Thread.Sleep(1000);

status = cl.IsBusy;

}

Console.WriteLine("xmlData: " + xmlData);

and here is my callback function:

void cl_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)

{

xmlData = e.Result;

Console.WriteLine("xmlData: " + xmlData);

}

Thanks for any help you can give me!

The problem with using the reader is that you require your tags to be in a specific order. However that's not how XML works.

You could use the XML-to-LINQ, but that adds 50k to your XAP (why isn't it that these standard Dlls are part of the install grrrr?)

I'm surprised to see an XML tutorial for Silverlight that doesn't implement LINQ. Any reason for not using it?
