    <p>Even if the TextChanged event is usable for that i think the performance will be horrible if you have an already filled TextBox and simply enter another character.</p> <p>So to get this really to work smooth you need some additional efforts. Maybe restart a timer on every TextChanged event (1000ms), so the user won't be intercepted by entering something fast and start the word counting only when the timer event is fired up.</p> <p>Or think about putting the split and count algorithm into a background worker and maybe (or not) cancel the count if the user is going to enter something again into the box.</p> <h3>Update</h3> <p>Ok, here is an implementation example:</p> <pre><code>using System; using System.ComponentModel; using System.Windows.Forms; namespace WindowsFormsApplication { public partial class FormMain : Form { public FormMain() { InitializeComponent(); } private void textBox1_TextChanged(object sender, EventArgs e) { RestartTimer(); } private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) { var textToAnalyze = textBox1.Text; if (e.Cancel) { // ToDo: if we have a more complex algorithm check this // variable regulary to abort your count algorithm. } var words = textToAnalyze.Split(); e.Result = words.Length; } private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Cancelled || e.Error != null) { // ToDo: Something bad happened and no results are available. } var count = e.Result as int?; if (count != null) { var message = String.Format("We found {0} words in the text.", count.Value); MessageBox.Show(message); } } private void timer1_Tick(object sender, EventArgs e) { if (backgroundWorker1.IsBusy) { // ToDo: If we already run, should we let it run or restart it? return; } timer1.Stop(); backgroundWorker1.RunWorkerAsync(); } private void RestartTimer() { if (backgroundWorker1.IsBusy) { // If BackgroundWorker should stop it's counting backgroundWorker1.CancelAsync(); } timer1.Stop(); timer1.Start(); } } } </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.
