    <p>If the fancy scroll bar can be implemented as another control (your image actually looks like that), here is the code of a ListBox that supports custom scrolling:</p> <pre><code>Imports System.Runtime.InteropServices Public Class CustomScrollListBox Inherits ListBox Public Sub Scroll(ByVal percentage As Single) If (percentage &lt; 0.0!) Then Throw New ArgumentException(Nothing, "percentage") End If ' Sends the scroll / set position Windows message Const WM_VSCROLL As Integer = &amp;H115 Const SB_THUMBPOSITION As Integer = 4 Dim wp As Integer = CInt(((percentage * MyBase.Items.Count) * 65536.0!)) + SB_THUMBPOSITION CustomScrollListBox.SendMessage(MyBase.Handle, WM_VSCROLL, New IntPtr(wp), IntPtr.Zero) End Sub &lt;DllImport("user32.dll")&gt; _ Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal msg As Integer, ByVal wParam As IntPtr, ByVal lParam As IntPtr) As IntPtr End Function Protected Overrides ReadOnly Property CreateParams() As CreateParams Get ' Removes the vertical scroll window style Dim p As CreateParams = MyBase.CreateParams Const WS_VSCROLL As Integer = &amp;H200000 p.Style = (p.Style And -WS_VSCROLL) Return p End Get End Property End Class </code></pre> <p>And here is a sample form that uses it. I have implemented the custom scroller as a standard Trackbar (trackBar1) for the example:</p> <pre><code>Public Class Form1 Private trackBar As TrackBar Private listBox As CustomScrollListBox Protected Overrides Sub OnLoad(ByVal e As System.EventArgs) ' initialize some listbox props listBox = New CustomScrollListBox listBox.Location = New Point(&amp;H19, 210) listBox.Name = "listBox2" listBox.Size = New Size((&amp;H17D - Me.TrackBar1.Width), &amp;HAD) listBox.TabIndex = 1 MyBase.Controls.Add(listBox) ' add some items Dim i As Integer For i = 0 To 100 - 1 listBox.Items.Add(("item" &amp; i)) Next i End Sub Private Sub TrackBar1_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TrackBar1.Scroll ' compute trackbar's position as a percentage listBox.Scroll(CSng(TrackBar1.Maximum - TrackBar1.Value) / TrackBar1.Maximum - TrackBar1.Minimum) End Sub End Class </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.
