Communicate with different Silverlight Application in the browser

1. Create two Silverlight Applications which are sharing the same asp.net application. When rebuilt the two SL application,the *.xap files will be generated to the folder ./ClientBin

 

2. Imported the two Silverlight xap to the same asp.net or html page.

 

3. In the two SilverLight Applications add the namespace "using System.Windows.Messaging;"

 

4. In the first SL application,which we call it sender,add the following code accordingly.

LocalMessageSender msgSender = new LocalMessageSender("MyReceiver"); // the p<a href="/tag/ara/" target="_blank" class="keywords">ara</a> is the message receiver name private void btnSubmit_Click(object sender,RoutedEventArgs e) { msgSender.SendAsync("this message from the f<a href="/tag/irs/" target="_blank" class="keywords">irs</a>t app"); }

 

5. In the second SL application,which we call it Receiver,add the following code accordingly.

// in the pageload event. LocalMessageReceiver receiver = new LocalMessageReceiver("MyReceiver"); receiver.MessageReceived += new EventHandler<MessageReceivedEventArgs>(receiver_MessageReceived); receiver.Listen(); void receiver_MessageReceived(object sender,MessageReceivedEventArgs e) { tbContent.Text = e.Message; }

 

when we run the application,and click the button in the first application,the message will be displayed in the second Silverlight application.
