    <p>Here is one way to get the topmost form that uses Win32 (not very elegant, but it works):</p> <pre><code>public const int GW_HWNDNEXT = 2; // The next window is below the specified window public const int GW_HWNDPREV = 3; // The previous window is above [DllImport("user32.dll")] static extern IntPtr GetTopWindow(IntPtr hWnd); [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] static extern bool IsWindowVisible(IntPtr hWnd); [DllImport("user32.dll", CharSet = CharSet.Auto, EntryPoint = "GetWindow", SetLastError = true)] public static extern IntPtr GetNextWindow(IntPtr hwnd, [MarshalAs(UnmanagedType.U4)] int wFlag); /// &lt;summary&gt; /// Searches for the topmost visible form of your app in all the forms opened in the current Windows session. /// &lt;/summary&gt; /// &lt;param name="hWnd_mainFrm"&gt;Handle of the main form&lt;/param&gt; /// &lt;returns&gt;The Form that is currently TopMost, or null&lt;/returns&gt; public static Form GetTopMostWindow(IntPtr hWnd_mainFrm) { Form frm = null; IntPtr hwnd = GetTopWindow((IntPtr)null); if (hwnd != IntPtr.Zero) { while ((!IsWindowVisible(hwnd) || frm == null) &amp;&amp; hwnd != hWnd_mainFrm) { // Get next window under the current handler hwnd = GetNextWindow(hwnd, GW_HWNDNEXT); try { frm = (Form)Form.FromHandle(hwnd); } catch { // Weird behaviour: In some cases, trying to cast to a Form a handle of an object // that isn't a form will just return null. In other cases, will throw an exception. } } } return frm; } </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
