How to specify the kendo schema to use in a div - asp.net-mvc

I have the following code in my View using the kendo grid:
<div id="MyGrid"
data-role="grid"
data-editable="true"
data-toolbar='[{ template: kendo.template($("#ToolbarTemplate").html()) }]'
data-columns='[
{ field: "Description" },
{ field: "Value" },
{ command: [{name: "destroy", template: kendo.template($("#DeleteTemplate").html())}], width: 60}
]'
data-bind="source: MyDataSource">
Then in a script section a have:
kendo.bind($("#MyGrid"), MyViewModel)
Everything is working fine. However, now I'm trying to implement a validation to let the user knows that any of the fields inside the Kendo Grid is required. I saw that it can be done in the schema as follow (Kendo doc link):
schema: {
model: {
id: "ProductID",
fields: {
ProductID: { editable: false, nullable: true },
ProductName: { validation: { required: true } },
UnitPrice: { type: "number", validation: { required: true, min: 1} },
Discontinued: { type: "boolean" },
UnitsInStock: { type: "number", validation: { min: 0, required: true } }
}
}
}
Is there a way to do the same in the div tag as the rest of the attributes? Does data-schema attribute exist?
Thanks in advance

You are missing the kendo validator initialization part in your code. Please refer the following links for documentation and demo

Call knockout method inside kendo grid

I have simple kendo UI grid
$("#Grid").kendoGrid({
dataSource: {
serverPaging: true,
transport: {
read: "Course/Read",
dataType: "json"
},
schema: {
data: "Data",
total: "Total",
errors: "Errors"
},
pageSize: 10
},
pageable: true,
columns:
[
{ field: "CourseName", title: "Name", width: 100 },
{ field: "SpecialtyName", title: "Specialty", width: 100, filterable: false },
{ title: "Edit", template: '<span class="EditIcon"><i data-bind="click:Edit(#: Id#)" class="fa fa-edit"></i></span>', width: 50 },
]
});
the problem is when I am using:
data-bind="click:Edit(#: Id#)"
when click on edit calling function not work inside kendo grid notice that both the grid and function inside knockout viewmodel
function viewmodel() {
var self = this;
self.Load = function () {
$("#Grid").kendoGrid({
dataSource: {
type: "aspnetmvc-ajax",
serverPaging: true,
transport: {
read: "Course/Read",
dataType: "json"
},
schema: {
data: "Data",
total: "Total",
errors: "Errors"
},
pageSize: 10
},
pageable: true,
columns:
[
{ field: "CourseName", title: "Name", width: 100 },
{ field: "SpecialtyName", title: "Specialty", width: 100, filterable: false },
{ title: "Edit", template: '<span class="EditIcon"><i data-bind="click:Edit(#: Id#)" class="fa fa-edit"></i></span>', width: 50 },
]
});
}
self.Load();
self.Edit= function (Id) {
////////my code////////
}
}
everything work fine the binding retrieve data, extra except call knockout method inside kendo grid, appreciate any help thanks.
if anyone looking for answer or open this post, this is not related to kendo, this is because the grid render rows after knockout binding done, so you can take viewmodel object in temp var in javascript and use it like tempvar.callfunction().

Kendo Filter is Not Working on the Date Column

I have an grid with date column in which I applied a filterable option and i did not get any results when I filter.
My grid:
var element = $("#grid").kendoGrid({
dataSource: {
data: gridDataSource,
schema: {
model: {
fields: {
Date: { type: "date", editable: false },
}
}
}
},
scrollable: true,
filterable : true,
columns: [
{
"field": "Date", "title": "Date", "format": "{0:MM/dd/yyyy}", filterable : {ui: function (e) {e.kendoDatePicker({format: "MM/dd/yyyy"})}}, width: "100px" }],
});
Probably is missing .data("kendoGrid"); in end of kendogrid() declaration.
For convinience I did an working example.
Hope this help
ps: Filter by 1966/01/27 in example to check.

Sorting in Kendo Grid

I am sorting Kendo grid dynamically.
var sortedName = $('##Html.FieldIdFor(model => model.SortingName)').val();
var sortedOrderName = $('##Html.FieldIdFor(model => model.SortingOrderName)').val();
sort: { field: sortedName, dir: sortedOrderName },
it is working fine but this is sorting records by pagination. What I want is to sort all the data fetched from the database
I recommend looking at the remote data binding example: Kendo Grid Remote-Data-Binding
Note the Data Source settings for serverPaging, serverFiltering and server sorting:
dataSource: {
type: "odata",
transport: {
read: "//demos.telerik.com/kendo-ui/service/Northwind.svc/Orders"
},
schema: {
model: {
fields: {
OrderID: { type: "number" },
Freight: { type: "number" },
ShipName: { type: "string" },
OrderDate: { type: "date" },
ShipCity: { type: "string" }
}
}
},
pageSize: 20,
serverPaging: true,
serverFiltering: true,
serverSorting: true
}

Kendo UI Grid Update button not firing

I am developing a KendoUI Grid with Inline editable option in javascript and can't make Update button to fire click event and post the data to server side update event. Clicking on Update button won't even update the grid on client.
Hope someone can help me point out what I am doing wrong here.
This is not a duplicate to this as I have tired the jfiddle link in the answer and it is not working too.
kendo UI grid update function wont fire
<div id="grid"></div>
#section Scripts{
<script type="text/javascript">
$(function () {
var dataSource = new kendo.data.DataSource({
transport: {
read: {
url: "Home/GetPupilsAsJson",
dataType: 'json'
},
update: {
url: "Home/UpdatePupils",
dataType: 'json',
type: 'POST'
}
},
pageSize: 5,
autoSync: true
});
$('#grid').kendoGrid({
dataSource: dataSource,
editable: "inline",
pageable: true,
columns: [{
field: "Id",
title: "Id",
width: 150,
hidden: true
}, {
field: "Firstname",
title: "Firstname",
width: 150
}, {
field: "Lastname",
title: "Lastname",
width: 150
}, {
field: "DateOfBirth",
title: "DateOfBirth",
width: 150
}, {
field: "Class",
title: "Class",
width: 150
}, {
field: "Year",
title: "Year",
width: 150
},
{
command: ["edit"],
width: 150
}]
});
});
</script>
}
HomeController
public ActionResult GetPupilsAsJson()
{
return Json(GetPupils(), JsonRequestBehavior.AllowGet);
}
[AcceptVerbs(HttpVerbs.Post)]
[HttpPost]
public void UpdatePupils(Pupil p)
{
//never reach here
}
I don't know why but fixed it by putting schema information.
schema: {
model: {
id: "Id",
fields: {
Firstname: { editable: true, validation: { required: true } },
Lastname: { validation: { required: true } },
DateOfBirth: { validation: { required: true } },
Class: { validation: { required: true } },
Year: { validation: { required: true } }
}
}
}
Use #Url.Action("GetPupilsAsJson", "Home")' so no need to pass base url in your update action like this BASEURL+ "Home/GetPupilsAsJson".
var dataSource = new kendo.data.DataSource({
transport: {
read: {
url: '#Url.Action("GetPupilsAsJson", "Home")',
dataType: 'json'
},
update: {
url:'#Url.Action("UpdatePupils", "Home")',
dataType: 'json',
type: 'POST'
}
},
pageSize: 5,
autoSync: true
});
use parameter map to pass model values
<script type="text/javascript">
$(function () {
var dataSource = new kendo.data.DataSource({
transport: {
read: {
url: '#Url.Action("GetPupilsAsJson", "Home")',,
dataType: 'json'
},
update: {
url: '#Url.Action("UpdatePupils", "Home")',
dataType: 'json',
type: 'POST'
},
parameterMap: function (options, operation) {
if (operation !== "read" && options.models) {
return { models: kendo.stringify(options.models) };
}
}
},
pageSize: 5,
autoSync: true
});
Call Controller with parameterMap
public JsonResult UpdatePupils(string models)
{
return Json(..);
}
Is any of your cell text has HTML tags like < or >, remove them and click on update. The update event will fire.

Kendo.Web Grid Popup Create with ComboBox

I am using the free Kendo web controls. I have used the grid view in several places before and decided to use the popup style editing for my current project.
I have most of it working. I have three combo boxes for category, bank account and payee and when I edit an existing item, the model object passed back to my MVC action has the correct values in it. However, when I click on the create button, the three combo box values are returned as null to the controller.
Here is the CSHTML code for this view:
#using System
#using System.Linq
#{
ViewBag.Title = "Transactions";
}
#section Head
{
<link href="~/Content/kendo/kendo.common.min.css" rel="stylesheet" />
<link href="~/Content/kendo/kendo.default.min.css" rel="stylesheet" />
<script src="~/Scripts/kendo/kendo.web.min.js"> </script>
}
#section featured
{
<section class="featured">

</hgroup>
</div>
</section>

The binding to the kendo combo box must be working, otherwise the edit would fail as well. All I can think is that the object is not created correctly. Also, it selects the first item in the combo box by default, but even so, does not bind the value.
Following is the code for my create and update actions:
[HttpPost]
public ActionResult Create(TransactionModel transactionModel)
{
var transaction = _moneyBO.CreateTransaction();
Mapper.Map(transactionModel, transaction);
_moneyBO.UpdateTransaction(transaction);
return Json(Mapper.Map<TransactionModel>(transaction));
}
public ActionResult Update(TransactionModel transactionModel)
{
var transaction = _moneyBO.Transactions.SingleOrDefault(x => x.Id == transactionModel.Id);
if (transaction == null)
return View("NotFound");
Mapper.Map(transactionModel, transaction);
_moneyBO.UpdateTransaction(transaction);
return Json(Mapper.Map<TransactionModel>(transaction));
}
I have not found a good example using the popup custom edit. The example on the Kendo site works inline, but if you change the example to popup it does not work.
I have a same problem. Write, if you solve it, please
I found, that Kendo think that "null" (default for int?) is ObservableObject (while initialization of ComboBox), thats why it can't be parsed to "number". If you edit item (not create), value id not "null" and model bindind work's fine
Not sure if it's the only issue here but in your code example it looks like the initialization of your dropdown isn't quite correct. You have written dataValueFileld which should be dataValueField
kendoDropDownList({
autoBind: true,
dataValueFileld: "Id", <-- Incorrect spelling
dataTextField: "Name",
dataSource:
{
type: "json",
transport: { read: "#Url.Action("GetPayees", "Transaction")" }
}
});
