Is it purely to enforce good practice, or are there technical reasons for this? ...
Hopefully this is simple - I DataBind a bunch of labels and text controls in a Silverlight application (to DependencyProperties that I create in my class), but of course the text is empty at design time.

Any shortcuts? ...
