Hello,
I've been running into a problem when trying to validate the pop-ups from a grid edit.
When I have everything set up as in the code below, errors from the controller are returned as a string on a new page, rather than to the ValidationSummary or ValidationMessage Tags.
Here is the PartialView used as a template for the Pop-up editor
@model CopyOrder<scriptsrc="~/Scripts/jquery.validate.unobtrusive.js"></script><scriptsrc="~/Scripts/jquery.validate.unobtrusive.min.js"></script><divclass="EditorContainer"> <divid="OrderEditorSubHeader">Order <b>Information</b></div>@using (Html.BeginForm("OrderCopy", "OrderManagement")){ <divclass="form-group"> @Html.Label("Copy Order ID") @(Html.Kendo().ComboBoxFor(m=>m.CopyOrderID) //.Name("CopyOrderID") .Filter("contains") .Placeholder("Please Select") .DataSource(dataSource => dataSource.Read(read => read.Url("/OrderManagement/OrderID_Select"))) .DataTextField("Text") .DataValueField("Value") .Suggest(true) .HtmlAttributes(new { @class = "form-control" })) @Html.ValidationMessageFor(m => m.CopyOrderID) </div> <divclass="form-group"> @Html.Label("Copy To Customer") @(Html.Kendo().ComboBoxFor(m=>m.CopyCustomerID) //.Name("CopyCustomerID") .Filter("contains") .Placeholder("Please Select") .DataSource(dataSource => dataSource.Read(read => { read.Action("AvailableCustomers_Select", "OrderManagement") .Data("filterAvailableCustomers"); }) .ServerFiltering(true) ) .DataTextField("Text") .DataValueField("Value") .Suggest(true) .Enable(false) .AutoBind(false) .ValuePrimitive(true) .CascadeFrom("CopyOrderID") .HtmlAttributes(new { @class = "form-control" })) @Html.ValidationMessageFor(m => m.CopyCustomerID) </div> <inputid="submitbtn"type="submit"value="Save"/> @Html.ValidationSummary(false)}Here is the Controller code
[HttpPost] publicActionResult OrderCopy([DataSourceRequest] DataSourceRequest request, Ops.Models.CopyOrder Copy) { var db = newOps.Models.Ops_Entities(); if(ModelState.IsValid) { try { //A bunch of Linq Queries here //One of them causes a NullReference Exception
db.OrderGroups.Add(newGroup); db.SaveChanges(); returnRedirectToAction("Orders"); } catch(NullReferenceException) {//Code reaches this point when I trigger the error in question
//Problem is that when it is returned, a new page is opened just displaying the error message as a string
ModelState.AddModelError(String.Empty, "Invalid Selection"); var failmodel2 = (newList<Ops.Models.CopyOrder> { Copy }).ToList().ToDataSourceResult(request, ModelState); returnJson(failmodel2, JsonRequestBehavior.AllowGet); } } var failmodel = newList<Ops.Models.CopyOrder>(); returnJson(failmodel.ToDataSourceResult(request, ModelState)); }and my kendo grid
@(Html.Kendo().Grid<Ops.Models.vw_Orders>() .Name("Orders") .EnableCustomBinding(true) .Columns(columns => { columns.Bound(p => p.SchoolYear) .Title("Year"); columns.Bound(p => p.Company) .Title("School Name") .ClientTemplate("<span><ahref='/CustomerManagement/SchoolInfo?CustomerID=#=CustomerID#'>#=Company#</a></span>"); columns.Bound(p => p.MasterOrderID) .Title("Order ID"); columns.Bound(p => p.GroupName); columns.Bound(p => p.Type); columns.Bound(p => p.Program); columns.Bound(p => p.Status) .ClientTemplate("<span>#=Status#</span>"); columns.Bound(p => p.AddUser); columns.Bound(p => p.SalesTerritory) .Title("Territory"); }) .Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("OrderGroupEdit")) .ToolBar(toolBar => { toolBar.Create().Text("Add Order"); toolBar.Custom().Text("Copy Order").HtmlAttributes(new { id = "openCopyWindow" }); toolBar.Custom().Text("Add Service Item").HtmlAttributes(new { id = "openServiceItemWindow" }); toolBar.Custom().Text("Get Job Master").HtmlAttributes(new { id = "openJobMastWindow" }); }) .Pageable(o => { o.PageSizes(new[] { 11, 20, 50, 100, 1000 }); o.ButtonCount(4); }) .Sortable() .Filterable(f => f.Operators(o => o.ForString(d => d .Clear() .Contains("Contains") .IsEqualTo("Equal To") ) ) ) .Events(e => e.DataBound("onDataBound")) .ClientDetailTemplateId("OrderDetails") .DataSource(dataSource => dataSource .Ajax() .Model(model => model.Id(m => m.MasterOrderID)) .PageSize(100) .Read(read => read.Action("OrderSearch", "OrderManagement")) .Create(create => create.Action("OrderCreate", "OrderManagement")) .ServerOperation(true) ) )@(Html.Kendo().Window() .Name("window") .Title("Copy Order") .Content("") .LoadContentFrom("CopyOrder", "OrderManagement") .Draggable() .Visible(false) .Width(800) //.Events(e => e.Close("ManualWindow_close")))
and the js opening the window
$(document).ready(function() { $("#openCopyWindow").click(function(e) { e.preventDefault(); varwindow = $("#window").data("kendoWindow"); window.center().open(); }); })
