title: Remove ability of a Usercontrol to get focus
body: <p>while designing my user control, i encountered the following problem:</p>
  
  <p>i would like to set the UserControl.CanGetFocus to false, which is not possible due an error message telling me that a control unable to receive focus can not contain elements who are able to receive focus.</p>
  
  <p>but as i don't want them to actually receive any focus, i would like to disable this for the child-objects as well as for my user control. i can barely believe that there's no possiblity to prevent the child-controls to receive focus, no matter of what type they are? i currently use imageboxes and pictureboxes.</p>
  
  <p>already searched using google, always leading to the result that the property cannot be set to false under these conditions...</p>
