    <p>There is no way to do this in one method if I correctly understand your needs. Yes, except </p> <pre><code>Application.DoEvents(); </code></pre> <p>The main issue that you want use procedure-based approach but you should message-based. I'll try to explain.</p> <p>You have something like </p> <pre><code>public partial class MyForm : Form { ProgressBar progress; Button startTaskButton; void OnClick_startTaskButton(); </code></pre> <p>You want start some time-consuming task in background using Thread/Process/BackgroundWorker or ThreadPool. And you need that Form interact with user and show him task progress during mentioned task is executing.</p> <p>So you need break your ProgressStaff at least two methods: the first will start task executing and the second will react on task complete event.</p> <p>//Off top: As I see your ThirdPartyObject class doesn't receive instance of Form so you should syncronize manually.</p> <p>So your code will looks like this:</p> <pre><code>void OnClick_startTaskButton() { ProcessStuff(GetTask(), this); } private void ProcessStuff(Task sometask, Form progressform) { if (sometask.foo == "A") DoStuff(); //This one is SYNchronous else { ThirdPartyObject Q = new ThirdPartyObject(); Q.ProgessChanged += delegate(object sender, ProgressChangedEventArgs e) { TaskProgessChanged(sender, e); }; Q.TaskCompleted += delegate(object sender, TaskResult result) { TaskCompleted(sender, result); }; Q.Execute("X", "Y", "Z"); //This one executes ASYNchronous } } void TaskProgessChanged(object sender, ProgressChangedEventArgs e) { if (InvokeRequired) Invoke(TaskProgessChanged, new object[] {sender, e} ); else ShowProgress(e.ProgressPercentage); } void TaskCompleted(object sender, TaskResult result) { if (InvokeRequired) Invoke(TaskComplete, new object[] {sender, result} ); else { MessageBox.Show("Task is completed with result :" + result.ToString()); } } </code></pre> <p>======================</p> <p>Well, if you <strong>really</strong> want to fell like your ProcessStuff method executes synchronously and in the same time Form reflect progress and you can't divide ProcessStuff into two methods - you may modify my solutions into the following way:</p> <pre><code>private void ProcessStuff(Task sometask, Form progressform) { ProcessStuff(sometask, progressform, true); } private void ProcessStuff(Task sometask, Form progressform, bool isNewTask) { if (isNewTask) if (sometask.foo == "A") DoStuff(); //This one is SYNchronous else { ThirdPartyObject Q = new ThirdPartyObject(); Q.ProgessChanged += delegate(object sender, ProgressChangedEventArgs e) { progressform.ShowProgress(e.ProgressPercentage); }; Q.TaskCompleted += delegate(object sender, TaskResult result) { ProcessStuff(sometask, this, false); }; Q.Execute("X", "Y", "Z"); //This one executes ASYNchronous } else { if (InvokeRequired) Invoke(TaskComplete, new object[] {sender, result, isNewTask} ); else { //Task is completed MessageBox.Show("Task is completed"); } } } </code></pre> <p>But imho that will be bad style ;)</p> <p>(I don't check is this code compiled and suppose you haven't problems with that)</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.
