I just study the sliverlight .

I create three project.

the one sliverlight web project

and the other is sliverlight project ,

the last is wcf project.

I think the case is easy,but I  am wrong.

so I write the blog to note myself.

1) because the wcf project and sliverlight project is different domain,so  when the sliverlight web project call wcf service that throw the error:" cross-domain error" . I  search the message about this error with google, I found  that because the two project are diffenert domain, you must add xml file "crossdomain.xml" , the file contend is

crossdomain.xml

<?xml version="1.0"?><br /> <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd"><br /> <cross-domain-policy><br /> <allow-http-request-headers-from domain="*" headers="*"/><br /> <allow-http-request-headers-from domain="*" headers="SOAPAction" /></p> <p></cross-domain-policy>

clientaccesspolicy.xml

<?xml version="1.0" encoding="utf-8"?><br /> <access-policy><br /> <cross-domain-access><br /> <policy><br /> <allow-from http-request-headers="*"><br /> <domain uri="*"/><br /> </allow-from><br /> <grant-to><br /> <resource path="/" include-subpaths="true"/><br /> </grant-to><br /> </policy><br /> </cross-domain-access><br /> </access-policy>

2) sliverlight datagrid bind

private void Page1_Loaded(object sender, RoutedEventArgs e)<br /> {<br /> //Resource r = new Resource();<br /> //r.Name = "candu";</p> <p> //Binding b = new Binding();<br /> //b.Path = new PropertyPath("Name");<br /> //b.Mode = BindingMode.OneTime;</p> <p> //b.Source = r;</p> <p> //MyTextBlock.DataContext = r;</p> <p> //MyTextBlock.SetBinding(TextBlock.TextProperty, b);</p> <p> ////r.Name = "echo";<br /> ////MyTextBlock2.DataContext = r;<br /> //List<Resource> Resources = new List<Resource>();<br /> //Resources.Add(new Resource {Name="candu",Value ="1" });<br /> //Resources.Add(new Resource { Name = "echo", Value = "2" });<br /> //list1.ItemsSource = Resources;</p> <p> //Uri endpoint = new Uri("http://localhost:3917/handler/ResoureHandler.ashx");</p> <p> //WebRequest request = WebRequest.Create(endpoint);<br /> //request.Method = "POST";<br /> //request.ContentType = "application/x-www-form-urlencoded";<br /> //request.BeginGetResponse(new AsyncCallback(ResponseReady), request);<br /> Binding binding = new BasicHttpBinding();<br /> EndpointAddress endPoint = new EndpointAddress(<br /> "http://localhost:4545/Service1.svc");</p> <p> ServiceReference1.ResourceListPageServiceClient client = new ServiceReference1.ResourceListPageServiceClient(binding, endPoint);<br /> client.GetDataCompleted += new EventHandler<ServiceReference1.GetDataCompletedEventArgs>(client_GetPostsCompleted);<br /> client.GetDataAsync();</p> <p> }<br /> void client_GetPostsCompleted(object sender, ServiceReference1.GetDataCompletedEventArgs e)<br /> {<br /> if (e.Error == null)<br /> {<br /> DG_Resource.ItemsSource = e.Result;<br /> }<br /> }
