    <p>my question is: having a piece of code like that (communication via callback contract)</p> <pre><code>private void BroadcastMessage(DataEventArgs e) { DataEventHandler temp = DataEvent; if (temp != null) { foreach (DataEventHandler handler in temp.GetInvocationList()) { handler.BeginInvoke(this, e, EndAsync, null); } } } </code></pre> <p>and a callback contract</p> <pre><code>interface IDataCallback { [OperationContract(IsOneWay = true)] void EntityUpdateReceived(Entity entity); [OperationContract(IsOneWay = true)] void EntitiesUpdateReceived(List&lt;Entity&gt; entities); [OperationContract(IsOneWay = true)] void EntityDeleteReceived(Entity entity); [OperationContract(IsOneWay = true)] void EntitiesDeleteReceived(List&lt;Entity&gt; entities); [OperationContract(IsOneWay = true)] void SendLogOffMessage(string message); [OperationContract(IsOneWay = true)] void Logoff(); [OperationContract(IsOneWay = true)] void UpdatePlan(int userId); } </code></pre> <p>Do I have an assurance that the message will be broadcasted to all clients successfully, even if there were some, let's say network problems on the way ?? I mean, does the service automatcially try to deliver the message time after time until it succeeds, assuming the client is connected all the time but there were some problems during first delivery. I am asking because I do not know if I have to write additional code to have it guaranteed (service-client confirmation messages, etc.) I have a reliable session enabled in app.config, does reliable session solves the issue??</p> <p>Thanks in advance for your answer</p>

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.
