    <p>If what you wish is to launch a long process and to show the progress to the user, for example just like when you have a progress bar or something alike, you should use a <a href="http://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker.aspx" rel="nofollow noreferrer"><code>BackgroundWorker</code></a> to do the job. Here's a simple example:</p> <pre><code>public partial class ProgressForm : Form { // Assuming you have put all required controls on design... // Allowing some properties to be exposed for progress update... public properties MaximumProgress { set { progressBar1.Maximum = value; } public properties OverallProgress { set { progressBar1.Value = value; } } public partial class MainForm : Form { private BackgroundWorker backgroundWorker1; private ProgressForm _pf; public MainForm() { InitializeComponent(); backgroundWorker1 = new BackgroundWorker(); backgroundWorker1.WorkerReportsProgress = true; backgroundWorker1.DoWork += backgroundWorker1_DoWork; backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged; backgroundWorker1.RunWorkerCompleted += backgroundWorker1_RunWorkerCompleted; } // Assuming process starts on Button click. private void button1_Click(object sender, EventArgs e) { _pf = new ProgressForm(); _pf.MaximumProgress = number-of-elements-to-treat-returned-by-prevision-or-whatever-else; // Launching the background workder thread. backgroundWorker1.RunWorkerAsync(); // Triggering the DoWork event. // Then showing the progress form. _pf.ShowDialog(); } private void backgroundWorker1_DoWork(object sender, EventArgs e) { LaunchProcess(); } private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e) { _pf.OverallProgress = e.ProgressPercentage; } private void backgroundWorker1_RunWorkerCompleted(object sender, EventArgs e) { _pf.Close(); _pf.Dispose(); } private void LaunchProcess() { // Do some work here... // Reporting progress somewhere within the processed task backgroundWorker1.ReportProgress(); } } </code></pre> <p>This is not a compileable code as its purpose is to illustrate the main idea.</p> <p>Now, is this something alike you want to do?</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.
