title: .NET Property Grid - setting Browsable (bool) using App.config
body: <p>I would like to be able to set the visibility of a property on my property grid using App.config. I have tried :</p>
  
  <p><code>[Browsable(bool.Parse(Sytem.Configuration.ConfigurationSettings.AppSettings["testBool"]))]</code></p>
  
  <p>However Visual Studio 2008 would give me an error "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type". 
  Is there any way to set this bool on App.config?</p>
