title: c# Exception handling in 3 tier win forms app
body: <p>I have a 3 tier win forms app, it has a UI, BLL and DAL. I'm looking to add an exception handler that throws exceptions from the DAL all the way up to the UI so the user knows what the error is. I have tried using try{} catch{} and throwing it from the DAL, but this only throws it up to the BLL and stops there. is there any way to throw it right back to the UI?</p>
  
  <p>Thanks</p>
