Be aware that the code inside controllers executes on a server, without (direct) user supervision. It does not represent the end result (web page) that the user sees and interacts with. Furthermore, since this is not a WinForms project, you can't display message boxes. It makes no sense. If you do want to display a JavaScript alert, do so from within the Indexview. –Andrei V Mar 26 '14 at 10:00 Hi Andrei I want to show a alert before RedirectToAction if userId is not equal to 90043 –user3107343 Mar 26 '14 at 10:02 @user3107343 you can not –Grundy Mar 26 '14 at 10:04 To whom? Who must see this message? Is it just for debugging purposes? –Andrei V Mar 26 '14 at 10:04 add a comment| 4 Answers 4 active oldest votes up vote 3 down vote accepted You cannot show an alert from a controller. There is one way communication from the client to the server.The server can therefore not tell the client to do anything. The client requests and the server gives a response. You therefore need to use javascript when the response returns to show a message

controller GridDataSourceAction to the View, for display in the web page? This post has 1 verified answer | 2 Replies | 3 Followers Graeme Hart Points 960 Replied On: Thu, May 15 2014 9:56 AM Reply Hi igniteUI 13.1, MVC 4 I have an igGrid in my MVC view and it is populated via the DataGridModel.DataSourceURL. This calls a method in my controller to get the data, which takes the form of a strongly typed data table. Under certain circumstances something can go wrong in the controller which prevents the data from being retrieved. When this happens I need to get a message back to the View stating the problem. In this particular case the grid data is populated in part from an external website via an API which has a transactions per hour limit on it. When my system exceeds that limit I get no data data but I do get a message telling me how long I must wait before trying again. I want to get that message back to my view. eg "API call limit exceeded, try again after 35 minutes". I have tried various things but I can't figure out how to get an error message back to the View from the GridDataSource action method in my controller. Here it is as it stands right now: [GridDataSourceAction]public ActionResult GetTicketGridData(){ dsHelpdesk oTickets = new dsHelpdesk(); Exception oException = null; try { oTickets = clsInvoiceHelper.GetTicketData(); } catch (Exception ex) { oTickets = null; oException = ex; }// try if (oTickets == null) { return View(ACTION_InvoicePrepGetData, oException.Message); } else { return View(ACTION_InvoicePrepGetData, oTickets); }}// GetTicketGridData The above code results in the Load animation running forever and nothing comes back to my view. Under the hood a Object reference not set to an instance of an object exception is thrown, presumably because the datatable is not being returned from my controller method. The best that I have come up with is to clear out the datatable and insert a new row with the error message in one of its string fields. This just looks awful on the web page. If I could intercept this duff data r
