title: Custom controls in Visual Studio Lightswitch
body: <p>Can someone point me to an article or tutorial on using custom controls in Visual Studio Lightswitch? I'm trying to add a rich text box to a page, linked to a string property. When running the app, sometimes the field will show up, sometimes it won't. If it does show the width of the field is small, about 2 characters, but will expand when text is pasted inside. Saving doesn't work, though.</p>
  
  <p>I'm not even sure about whether or not I'm allowed to use controls like these in a Lightswitch app, even though custom controls are obviously supported. Are the custom controls restricted to a certain type or set?</p>
  
  <p>Thanks in advance for any assistance.</p>
