copied!<p>After reading Dupin's comments it seems logical that it isn't quite possible. I tried digging around the Elmah source code and came up with a couple of alternatives that might be worth sharing.</p> <p>The obvious alternative is stick with my original option of using the Logged event:</p> <pre><code>void ErrorLog_Logged(object sender, ErrorLoggedEventArgs args) { string sessionId = Session.SessionID; Session["ElmahId_" + sessionId] = args.Entry.Id; } </code></pre> <p>For a more direct solution it is possible to manually log the error with the following:</p> <pre><code>string errorId = Elmah.ErrorLog.GetDefault(HttpContext.Current) .Log(new Elmah.Error(filterContext.Exception)); </code></pre> <p>However, using this approach won't hit your filters or mail module and so on.</p> <p>After doing a bit of thinking and a little more searching, I came up with a new compromise. Still using the logged event but I've found a way to create a new unique key that can be passed to the view, by adding my own data to the exception.</p> <pre><code>string loggingKey = "ElmahId_" + Guid.NewGuid().ToString(); filterContext.Exception.Data.Add("LoggingKey", loggingKey); </code></pre> <p>This way I can pass the exception in my view model, which has this key value in the Data collection. The logged event would be changed to something like this:</p> <pre><code>void ErrorLog_Logged(object sender, ErrorLoggedEventArgs args) { string key = args.Entry.Error.Exception.Data["LoggingKey"].ToString(); Session[key] = args.Entry.Id; } </code></pre> <p>Then in the view I get the key from the model to then pull the Id from the Session collection.</p>
