    <h1>Stealing focus?</h1> <p>Consider if stealing focus is really the right way to solve your problem. It's quite tempting because the focus/non-focus difference is so obvious, and it's seems so easy. But it can quickly turn into a mess.</p> <p>Imagine you're using a third party component that steals focus sometimes when it's not supposed to. Annoyed, you'd write some code to grab focus back. Problem solved, not? But now instead of one, there's two components that are inappropriately stealing focus. And in the end, the user will be the victim of this focus war.</p> <h1>Subscribe to the <code>TextBox</code> events instead</h1> <p>Right now you're listening for events on the <code>Panel</code>. Another way of getting the <code>Panel</code> to react to the <code>MouseWheel</code> events is by instead subscribing to the appropriate event of the <code>Textbox</code> on your form, or even subscribe to the event for all controls on your form.</p> <p>Then in your handler, check to see if the mouse is within the bounds of the <code>Panel</code>. If so, instruct the panel to scroll. Don't forget to propagate the mouse event if necessary.</p> <p><strong>EDIT</strong></p> <p>Additional information:</p> <ul> <li>Documentation for <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.control.mousewheel.aspx" rel="nofollow">the <code>MouseWheel</code> event</a></li> <li>Code sample for <a href="http://www.codeproject.com/Articles/11014/How-to-route-events-in-a-Windows-Forms-application" rel="nofollow">subscribing to events</a></li> <li>Documentation on <a href="http://msdn.microsoft.com/en-us/library/aa983610%28v=vs.71%29.aspx" rel="nofollow">event handling in Windows Forms</a></li> </ul> <p>Hope this helps.</p>

    1. COArjen, I apologize - Your solution sounds so much smarter, but I don't really know how to do what you describe - Could you post some simple code / provide a link of what you mean in terms of subscribing to the events for this kind of situation? Thanks!!

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.
