title: Set focus to textbox in nested user control - Silverlight
body: <p>I'm not sure why this is so hard. I've got a logon form that's nested inside of a content frame in Silverlight 4. When I load the application, it detects if a user has authenticated. If not (obviously not initially) it loads the logon form. Pretty standard stuff...</p>
  
  <p>I can't, for the life of me, set focus on the username textbox. I've tried setting 'istabstop' = false on content controls, I've tried adding an this.Loaded event handler, setting the focus there (including using the htmlpage.plugin.focus method first).. I'm at my wits end [primarily because this should NOT be that hard]. </p>
  
  <p>Whatta I gotta do? </p>
  
  <p>Thanks,</p>
