    <p>Developers who know only C#, or only VB.Net, may not know that this is one of the larger differences between VB.NET and C#. </p> <p>I will <a href="http://visualstudiomagazine.com/Articles/2008/12/01/What-C-Devs-Should-Know-About-VB.aspx?Page=2" rel="nofollow noreferrer">shamelesssly copy</a> this nice explanation of VB events: VB uses a declarative syntax for attaching events. The <a href="http://msdn.microsoft.com/en-us/library/6k46st1y.aspx" rel="nofollow noreferrer">Handles</a> clause appears on the code that will handle the event. When appropriate, multiple methods can handle the same event, and multiple events can be handled by the same method. Use of the Handles clause relies on the <a href="http://msdn.microsoft.com/en-us/library/aty3352y.aspx" rel="nofollow noreferrer">WithEvents</a> modifier appearing on the declaration of the underlying variable such as a button. You can also attach property handlers using the <a href="http://msdn.microsoft.com/en-us/library/7taxzxka.aspx" rel="nofollow noreferrer">AddHandler</a> keyword, and remove them with RemoveHandler. For example</p> <pre><code>Friend WithEvents TextBox1 As System.Windows.Forms.TextBox Private Sub TextBox1_Leave(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles TextBox1.Leave 'Do Stuff ' End Sub </code></pre> <p>In C# you can't use the declarative syntax. You use += which is overloaded to act like the VB.Net AddHandler. Here's an example shamelessly stolen from <a href="https://stackoverflow.com/questions/1488573/how-to-raise-event-using-addhandler/1488623#1488623">tster's answer</a>:</p> <pre><code>public MyClass() { InitializeComponent(); textBox1.Leave += new EventHandler(testBox1_Leave); } void testBox1_Leave(object sender, EventArgs e) { //Do Stuff } </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.
