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 350k65567700 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.

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 2,21221624 I prefer a separate error page if the exception would cause problems with the rendering o
