    <p>Finally figured out. There are two parts of this puzzle - getting keys from cell editing control and getting keys from the DataGridView itself. Here's my code. To use it, you just need to subscribe to the custom event: <strong>keyPressHook</strong>.</p> <pre><code>class KeyPressAwareDataGridView : DataGridView { protected override void OnControlAdded(ControlEventArgs e) { this.subscribeEvents(e.Control); base.OnControlAdded(e); } protected override void OnControlRemoved(ControlEventArgs e) { this.unsubscribeEvents(e.Control); base.OnControlRemoved(e); } protected override bool ProcessDataGridViewKey(KeyEventArgs e) { bool procesedInternally = false; if (this.keyPressHook != null) { this.keyPressHook(this, e); procesedInternally = e.SuppressKeyPress; } if (procesedInternally) { return true; } else { return base.ProcessDataGridViewKey(e); } } private void subscribeEvents(Control control) { control.KeyDown += new KeyEventHandler(this.control_KeyDown); control.ControlAdded += new ControlEventHandler(this.control_ControlAdded); control.ControlRemoved += new ControlEventHandler(this.control_ControlRemoved); foreach (Control innerControl in control.Controls) { this.subscribeEvents(innerControl); } } private void unsubscribeEvents(Control control) { control.KeyDown -= new KeyEventHandler(this.control_KeyDown); control.ControlAdded -= new ControlEventHandler(this.control_ControlAdded); control.ControlRemoved -= new ControlEventHandler(this.control_ControlRemoved); foreach (Control innerControl in control.Controls) { this.unsubscribeEvents(innerControl); } } private void control_ControlAdded(object sender, ControlEventArgs e) { this.subscribeEvents(e.Control); } private void control_ControlRemoved(object sender, ControlEventArgs e) { this.unsubscribeEvents(e.Control); } private void control_KeyDown(object sender, KeyEventArgs e) { if (this.keyPressHook != null) { this.keyPressHook(this, e); } } public event KeyEventHandler keyPressHook; } </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.
