this article describes how to achieve this via p/invoke.

One of the nice things about the Visual Studio WinForms designers are the guidelines it draws onto design surfaces, aiding you in perfectly positioning your controls. These guidelines are known internally as snap lines, and by default each visual component inheriting from
Control gets four of these, representing the values of the control's
Margin property. However, this default designer doesn't include an implementation for the
BaseLine snap line, which is used to align controls via their contained text. This article shows how to create a custom designer to allow your controls to easily include this alignment option.
Some weeks ago I was trying to make parts of WebCopy's UI a little bit simpler via the expedient of hiding some of the more advanced (and consequently less used) options. And to do this, I created a basic toggle panel control. This worked rather nicely, and while writing it I thought I'd write a short article on adding keyboard support to WinForm controls.

ColorGrid in a standard
ToolStrip control, providing access to both the

ComboBox to support double clicks.
In my last post, I described how to drag and drop items to reorder a
ListView control. This time I'm going to describe the exact same technique, but this time for the more humble
