The tip with the WebClient worked for me. 
I will explain what the point was.
You have to know this:
http://msdn.microsoft.com/en-us/library/cc645032(VS.95).aspx[^]
What this text says is, that the Silverlight-Runtime looks first for a certain security-file when a resource is called from a server: the clientaccesspolicy.xml. When this file is not correct or not there at all then a security exception is thrown.
The problem was:
This file was not there so i had to put i manually on my localhost.
(I have apache. The clientaccesspolicy.xml has to be put in the htdocs folder.)
clientaccesspolicy.xml :
<?xml version="1.0" encoding="utf-8"?>
<access-policy>
<cross-domain-access>
<policy>
<allow-from>
<domain uri="*"/>
</allow-from>
<grant-to>
<resource path="/" include-subpaths="true"/>
</grant-to>
</policy>
</cross-domain-access>
</access-policy>
This is my Silverlight App :
public void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
Debug.WriteLine(e.Result);
}
public void XmlReadTest()
{
Uri url = new Uri("http://localhost/stage2.xml",UriKind.Absolute);
WebClient client = new WebClient();
client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);
client.DownloadStringAsync(url);
}

The Invoke method in WPF was moved to the Dispatcher object, which can be accessed via the Dispatcher property on the TextBox.

I have a mate who has had a web site built for him, based on C# and classic ASP, it is all very amateurish and I am considering offering to rebuild the thing properly. This will be a labour of love, or at least a few beers anyway. The design requires a lot of pictures/graphics but is predominately a data driven site.
I have no experience at all with WPF and Silverlight although I have started working through a book and I have built a number of ASPX sites. Also I am a lousy UI designer, I'm the great proponent of battleshit grey.
So, should I use it to learn Silverlight or just stick to ASPX. Professionally I am a winforms LOB developer so there will be limited professional benefit.

There's a significant learning curve if you're new
to WPF/Silverlight, although since you know .NET
already, it lessens the pain a bit.
Unlike ASP/ASP.NET, Silverlight apps run on the client. This allows
for much richer user experience on the client end that you can't get
from static HTML pages, and you get to use familiar language like C#/VB.NET.
When Silverlight is hosted in an ASP.NET web app, you can
then have processes running on both the server and the client.
If that is something you can (or need to) leverage to make
the site better and the learning curve is worth the time,
then go for it.
Otherwise, I would think ASP.NET would be a good option.

It turns out there are mild time constraints so I may save the SL for version 2. Thanks for your input Mark

Sample is fine.But,it wont find out if u enter numerics in text column.I need the entire code for that.When I click the button,it should check the values in textboxes and it should display.Could u help me?thanks

The samples you've been shown show how you can use Silverlight
validation.
You can change the samples to fit your needs.
You could loop through the strings using Char.IsDigit()/Char.IsLetter().
You could also use regular expression matching
bool isalldigits = Regex.IsMatch(inputstring, @"^([0-9]+)$");
bool isallletters = Regex.IsMatch(inputstring, @"^([a-zA-Z]+)$");

make an event handler for key_up. Attach it to the numeric data boxes. You still need to validate the data but this will make it easier on the user.

Hi folks!
Can anyone please help me with this:
I have two values (one manual input and one from a database) and I need to compare them/ validate them via ValidationRules and show errors if they do not match.
LOGIC: V1 == V2 => OK
V1 != V2 => NOK, Error
<TextBlock>
<TextBlock.Text>
<Binding ...>
<Binding.ValidationRules>
<localValidation:ValidateIt V1={Binding Path=...} V2={Binding Path=}/>
</Binding.ValidationRules/>
<TextBlock.Text/>
</TextBlock>
where
public class ValidateIt : ValidationRule
public int V1 {get;set;}
public int V2 {get;set;}
Unfortunately it tells me, that V1 and V2 cannot be bound due to the fact, that these are no DependencyProperties.
I'm stuck...
Thanks in advance,
eza

They don't need to be DependencyPropety's to be bound. There's a lightweight way of achieving what you want using POCO's. If you take a look at my sample here[^], you'll see that I'm handling the validation based on a ViewModel, which is totally none-DP based.

What does 'not working' mean ? We're not going to run your c ode to try to work that out. Have you debugged it ? What do you expect to happen ? What does happen ? Where does it go wrong ?

Hi,
I develop a custom control in VS 2008 and in that control is a DP property of a custom class.
The class has mainly two DP properties of type System.Globalization.CultureInfo and System.Globalization.Calendar. The class derives from DependencyObject.
So when in design time I choose a value for the class, the designer generates xaml code similar to:
<CustomControl.Culture>
<Culture Culture="Deutsch (Deutschland)">
<Culture.Calendar>
<my:GregorianCalendar />
<Culture.Calendar>
</Culture>
</CustomControl.Culture>
But what I want is following:
<CustomControl.Culture>
<Culture Culture="Deutsch (Deutschland)" Calendar="Gregorian Localized">
</Culture>
</CustomControl.Culture>
I adorned the Calendar DP property in the custom class with a TypeConverterAttribute and an ValueSerializerAttribute and built a design dll adding the attributes to the metadata store but nothing is working.
If I write the code in xaml in the second form the designer accepts it and all is fine, but every time
I change the Calendar property in the property browser, the designer changes the code to the first form.
If I implement the custom class derived from object without DP properties, the designer generates code in the second form.
Any ideas if I can influence the designer generated code?
Thanks,
Thomas.
