How Do I Detect Design-Time Vs Run-Time in a .NET Control?

When you're designing custom controls in Visual Studio .NET, you'll often need to distinguish between design-time and run-time. You could, for example, load a static image, or create a made-up DataSource at design-time while you use a real image or DataSource at run-time. The following snippet allows you to determine whether you're currently in design-time or not.
if (this.Site != null && this.Site.DesignMode == true)
  // Design Mode
  // Run-time
