    <p>I am trying to accomplish the following functionality,</p> <p>I get a <code>HttpRequest</code> and based on the request, i will create a new thread and then set some data for this thread [ local and thread specific data ] and then i will spin the thread. In the thread, i must be able to consume that data that i initialized before creating this thread anywhere before this thread ends its life.</p> <p>I tried this sample and here, the greeting variable inside the thread was null. Any idea of how do i accomplish this process.</p> <pre><code>class Program { [ThreadStatic] static string greeting = "Greetings from the current thread"; static void Main() { Console.WriteLine(greeting); // prints initial value greeting = "Goodbye from the main thread"; Thread t = new Thread(ThreadMethod); t.Start(); t.Join(); Console.WriteLine(greeting); // prints the main thread's copy Console.ReadKey(); } static void ThreadMethod() { // I am getting greeting as null inside this thread method. Console.WriteLine(greeting); // prints nothing as greeting initialized on main thread greeting = "Hello from the second thread"; // only affects the second thread's copy Console.WriteLine(greeting); } } </code></pre> <p><strong>EDIT</strong> I am trying to accomplish something like this</p> <pre><code>class ThreadTest { static void Main() { var tcp = new ThreadContextData(); Thread t = new Thread(ThreadMethod); tcp.SetThreadContext("hi.. from t1"); t.Start(); t.Join(); Thread t2 = new Thread(ThreadMethod); tcp.SetThreadContext("hello.. from t2"); t2.Start(); t2.Join(); Console.ReadKey(); } static void ThreadMethod() { Console.WriteLine(new ThreadContextData().GetThreadContextValue()); } } public class ThreadContextData { static ThreadLocal&lt;string&gt; greeting; static ThreadContextData() { greeting = new ThreadLocal&lt;string&gt;(() =&gt; ""); } public void SetThreadContext(string contextValue) { greeting.Value = contextValue; } public string GetThreadContextValue() { return greeting.Value; } public void ClearThreadContextValue() { greeting.Value = null; } } </code></pre>

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.
