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 error message 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 how to display 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 row I could work around this but I can't find the right event eg a AfterDataLoaded event on the grid or igDatas
