    <p>I've been doing some research on this and I got nothing. I have a server and client.</p> <p>My client does request to the server and the server runs some callbacks. This works fine. But now, there are some functions from the clients I need to call from the server and are not a result of a client call so I can't use callbacks there. I'm using WCF and .net 4.0</p> <p>Any suggestions?</p> <p>CLIENT:</p> <pre><code>using System; using System.ServiceModel; using System.ServiceModel.Channels; using System.Runtime.Serialization; using System.IO; using System.Collections; namespace WCFClient { [ServiceContract(SessionMode = SessionMode.Required, CallbackContract = typeof(ICallbacks))] public interface IMessageHandler { [OperationContract] void HandleMessage(); } public interface ICallbacks { [OperationContract(IsOneWay = true)] void QueuePaths_Callback(string cPath, string EPath, string RPath, string IPath, string OPath); } public class Callbacks : ICallbacks { public void QueuePaths_Callback(string cPath) { Console.WriteLine("QueuePaths_Callback: " + cPath); } } class Program { static void Main(string[] args) { Callbacks myCallbacks = new Callbacks(); DuplexChannelFactory&lt;IMessageHandler&gt; pipeFactory = new DuplexChannelFactory&lt;IMessageHandler&gt;( myCallbacks, new NetNamedPipeBinding(), new EndpointAddress( "net.pipe://localhost/PipeReverse")); IMessageHandler pipeProxy = pipeFactory.CreateChannel(); while (true) { string str = Console.ReadLine(); pipeProxy.HandleMessage();//send the type for example } } public void IWANTTOCALLTHISFROMSERVER() { } } } </code></pre> <p>SERVER:</p> <pre><code>namespace WCFServer { [ServiceContract(SessionMode = SessionMode.Required, CallbackContract = typeof(ICallbacks))] public interface IMessageHandler { [OperationContract] void HandleMessage(); } public interface ICallbacks { [OperationContract(IsOneWay = true)] void QueuePaths_Callback(string cPath); } public class StringReverser : IMessageHandler { public void HandleMessage()//handle the type and do the request { ICallbacks callbacks = OperationContext.Current.GetCallbackChannel&lt;ICallbacks&gt;(); callbacks.QueuePaths_Callback("path1"); } } class Program { static void Main(string[] args) { using (ServiceHost host = new ServiceHost( typeof(StringReverser), new Uri[]{ new Uri("net.pipe://localhost") })) { host.AddServiceEndpoint(typeof(IMessageHandler), new NetNamedPipeBinding(), "PipeReverse"); host. host.Open(); Console.WriteLine("Service is available. " + "Press &lt;ENTER&gt; to exit."); Console.ReadLine(); //BLA BLA BLA //CALL IWANTTOCALLTHISFROMSERVER(); host.Close(); } } } } </code></pre>

    1. COSo basically you want to inform the client that something happened on the server?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
