title: Prevent code from running only in visual studio designer
body: <p>I have a custom control that I have written that does some location checking in the Load event of the control.  This location checking moves the control to a specific location on the screen based on settings in its parent control.  This code works as expected when I compile and run the application.</p>
  
  <p>However, when using the Visual Studio designer, it causes my control to be painted outside of the viewable area and I cannot use the designer.  Is there a flag or attribute I can set to stop that snippet of code from running ONLY when in the Visual Studio designer?</p>
  
  <p>The only work around I have right now is to comment out the code, compile, launch designer, make my changes, then uncomment the code and re-compile.</p>
