For the client's computer, you'll want to redirect to an error page with an appropriate error message, perhaps including the exception message and stack trace if you want. On the server, you'll probably want to do some logging, either to the event log or to a log file. try { .... } catch (Exception ex) { this.Session["exceptionMessage"] = ex.Message; Response.Redirect( "ErrorDisplay.aspx" ); log.Write( ex.Message + ex.StackTrace ); } Note that the "log" above would have to be implemented by you, perhaps using log4net or some other logging utility. share|improve this answer edited Mar 16 '09 at 18:49 answered Mar 16 '09 at 18:25 tvanfosson 351k65571700 Upvoted for saying what I was trying to say. –Bobby Cannon Mar 16 '09 at 18:28 @tvanfosson - It is not that they cannot display message box on server side or client side. They should just avoid doing so. :) –Ramesh Mar 16 '09 at 18:38 @Ramesh -- clarified. –tvanfosson Mar 16 '09 at 18:51 add a comment| up vote 12 down vote You cannot just call messagebox.write cause you are disconnected from the client. You should register javascript code that shows a messagebox: this.RegisterClientScriptBlock(typeof(string), "key", string.Format("alert('{0}');", ex.Message), true); share|improve this answer answered Mar 16 '09 at 18:26 Michiel Overeem 2,21721624 I prefer a separate error
