I have seen this on "Wannes" comment and it´s exactly what it´s happening to me, but i don´t know how to resolve it because i don´t understand the problem. What i have is a simple grid working with CRUD.
The grid is a client table, whenever one wants to add a new client, he hits the new button and a popover appears. In this popover there are many fields, two of them are:
DataCriacao (the date when the client was created)
DataUpdate (the date when the client was updated)
This is my grid initialization code:
var dataSource = new kendo.data.DataSource({
transport:
{
read:
{
url: "data/clientes.php",
},
update:
{
url: "data/clientes.php?type=update",
type:"POST",
complete: function (e)
{
$("#gridClientes").data("kendoGrid").dataSource.read();
}
},
destroy:
{
url: "data/clientes.php?type=destroy",
type: "POST"
},
create:
{
url: "data/clientes.php?type=create",
type: "POST",
complete: function (e)
{
$("#gridClientes").data("kendoGrid").dataSource.read();
}
},
parameterMap: function(options, operation)
{
if (operation !== "read" && options.models)
{
return {models: kendo.stringify(options.models)};
}
}
},
error:function(e)
{
console.log(e);
},
batch: true,
pageSize: 8,
schema:
{
data: "data",
total: function(response)
{
return $(response.data).length;
},
model:
{
id: "idCliente",
fields:
{
**(other fields here)**
NomeUtilizadorCriador: {editable: false,validation: { required: false } },
DataCriacao: {type:"date", editable: false},
NomeUtilizadorUpdate: {editable: false, validation: { required: false } },
DataUpdate: {type:"date", editable: false},
}
}
}
});
$("#gridClientes").kendoGrid({
dataSource: dataSource,
pageable:
{
messages:
{
display: "{0} - {1} / {2} items",
empty: "0 items",
page: "Page",
of: "of {0}", //{0} is total amount of pages
itemsPerPage: "items per page",
first: "Go to the first page",
previous: "Go to the previous page",
next: "Go to the next page",
last: "Go to the last page",
refresh: "Refresh"
}
},
serverPaging: true,
height: 550,
toolbar:[{name: "create",text: $varGridQuartosBtnNovoPT},{name: "close",text: "X"}],
columns: [
**(other fields here)**
{ field: "NomeUtilizadorCriador", title: "Criado por", hidden: true},
{ field: "DataCriacao", title: "Criado em",format:"{0:yyyy-MM-dd}", hidden: true, width: "10px"},
{ field: "NomeUtilizadorUpdate", title: "Atualizado por", hidden: true},
{ field: "DataUpdate", title: "Atualizado em",format:"{0:yyyy-MM-dd}", hidden: true, width: "10px"},
{command:[{ text: "Detalhes", click: showDetails },{ name: "edit",text:
{edit:$varGridQuartosBtnEditarPT,update:$varGridQuartosBtnActualizarPT,cancel:$varGridQuartosBtnCancelarPT}},
{ name: "destroy",text:$varGridQuartosBtnApagarPT }],title:" ",width: "30px"}],
editable: {
mode:"popup",
template:kendo.template($("#popupGridClientes").html())
}
So, for example if i wanted to create a new client today, this is what appears in those two fields:
DataCriacao: Wed Apr 22 2015 10:46:02 GMT+0100 (WEST) (creation date)
DataUpdate: Wed Apr 22 2015 10:46:02 GMT+0100 (WEST) (update date)
Now if i want to update the client information, the problem appears:
DataUpdate: Wed Apr 22 2015 00:00:00 GMT+0100 (WEST) (update date)
These two fields are type DATE on my database. I don´t know what to do because i don´t understand where to start, does this helps?.
I don't know if I understand you correctly, but as you said, you store data in database in DATE format. That's why time part is zero in your example.
Check what data is in your database. It shouldn't have time.
Problem is in your backend/database side.

Help me code How to get value id from dataSource by row and change to current value default (1)
in line: var date = dataSource.get(1);
console.log(date.ProductName)

}
}
},
batch: true,
pageSize: 20,
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 } }
}
}
}
});
$("#grid").kendoGrid({
dataSource: dataSource,
selectable: true,
pageable: true,
height: 550,
toolbar: ["create"],
columns: [
"ProductName",
{ field: "UnitPrice", title: "Unit Price", format: "{0:c}", width: "120px" },
{ field: "UnitsInStock", title:"Units In Stock", width: "120px" },
{ field: "Discontinued", width: "120px", editor: customBoolEditor },

editable: "inline",
edit: function () {
var date = dataSource.get(1);
console.log(date.ProductName)
}
});
});
</script>
Now, when click edit, all rows only get fields of id 1. I want corresponding id instead of the default id 1.
edit
Fired when the user edits or creates a data item.
The event handler function context (available via the this keyword)
will be set to the widget instance.
EVENT DATA
e.container jQuery The jQuery object of the edit container
element, which wraps the editing UI. Depending on the Grid edit mode,
the container is different:
"incell" edit mode - the container element is a table cell
"inline" edit mode - the container is a table row
"popup" edit mode - the container is a Kendo UI Window element, which provides an easy way to obtain a reference to the Window widget object, e.g. to attach additional events.
e.model kendo.data.Model The data item which is
going to be edited. Use its isNew method to check if the data item is
new (created) or not (edited).
e.sender kendo.ui.Grid The widget instance which fired the event.
$("#grid").kendoGrid({
columns: [
{ field: "id" },
{ field: "name" },
{ field: "age" },
{ command: "edit" }
],
dataSource: {
data: [
{ id: 1, name: "Jane Doe", age: 30 },
{ id: 2, name: "John Doe", age: 33 }
],
schema: {
model: {
id: "id",
fields: {
"id": { type: "number" }
}
}
}
},
editable: "popup",
toolbar:["create"],
edit: function(e) {
console.log(e.model.id);
console.log(e.model.name);
}
});
Working example: edit event
Documentation: grid edit event
I'm quite new using kendo grids.
So far I've managed to do a few stuff and got a workaround for all my problems.
I have a grid with 2 columns.
One column is a product code that the user should enter, and the other is product quantity that should be filled automatically after the user enter the product code. This should be done on change event.
The product quantity is obtained by a service.
So far I have the following code:
var dataSource = new kendo.data.DataSource({
batch: false,
autoSync: false,
data: [],
pageSize: 20,
schema: {
model: {
id: "ProductID",
fields: {
ProductCode: { type: "string", validation: { required: true } },
ProductQuantity: { type: "number", validation: { required: false, editable: false } }
}
}
},
edit: function (e) {
if (e.model.isNew() == false) {
$('[name="ProductQuantity"]').attr("readonly", true);
}
},
change: function (e) {
if (e.action == "itemchange") {
debugger;
apModel.getProductQuantities(e.items[0].ProductCode).ifFetched().then(function (data) {
var data = JSON.parse(data.Response);
})
//how to access next cell???
$("#ap-grid").data("kendoGrid").saveRow();
}
}
});
$("#ap-grid").kendoGrid({
dataSource: dataSource,
pageable: false,
height: 550,
toolbar: ["create"],
columns: [
{ field: "ProductCode", title: "Product Code" },
{ field: "ProductQuantity", title: "Quantity" },
{ command: ["edit", "destroy"], title: " ", width: "250px" }],
editable: "inline",
});
I can't find a way how to access the next cell to add the data to it.
Can you give me a hint?
thanks in advance,
André
When you set e.items[0].ProductQuantity in OnChange event handler grid cell should automatically update value if datasource bind correctly.
According to kendo docs:
e.items - The array of data items that were affected (or read).
That means it reference at original row of datasource.
I have been having a tough time with grids lately, mostly getting them to display properly formatted JSON data that is being fetched from a webservice (which has been checked in VS2013, and JSONLint), if a second set of eyes could please have a look at my solution and tell me whats lacking? I am going bananas!
function SetTelerikGrid() {
// prepare the data object and consume data from web service,...
$.ajax({
type: "GET",
async: false,
url: "http://localhost:38312/SDMSService.svc/GetProductPositionsByLocation/0544",
datatype: "json",
success: function (ProductData, textStatus, jqXHR) {
// populate kendo location grid by data from successful ajax call,...
$("#LocationProductsGrid").kendoGrid({
dataSource: {
data: ProductData, // solution here was: **JSON.parse(LocationData)**
schema: {
model: {
fields: {
Date: { type: "string" },
ProductCode: { type: "string" },
StoreNum: { type: "string" },
ProductQty: { type: "int" }
}
}
},
pageSize: 20
},
height: 550,
scrollable: true,
sortable: true,
filterable: true,
pageable: {
input: true,
numeric: false
},
columns: [
{ field: "Date", title: "Date", width: "130px" },
{ field: "ProductCode", title: "Product Code", width: "130px" },
{ field: "StoreNum", title: "Store Number", width: "130px" },
{ field: "ProductQty", title: "Product Qty", width: "130px" }
]
});
}
});
}
There is a breaking change in ASP.NET Core, related to how the JSON serializer
works
You can probably mitigate this by adding a json option like this:
1:
change
services.AddMvc();
to
services
.AddMvc()
.AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());
OR
2:
public IActionResult Read()
{
// Override serializer settings per-action
return Json(
MyModel,
new JsonSerializerSettings { ContractResolver = new DefaultContractResolver() }
);
}

Finally figured it out, the 'ProductData' field - although in perfect JSON format - still required to be parsed as JSON in the datasource configuration, like so,...
Data: JSON.parse(ProductData)
I have to validate some data in kendoUI grid widget.
Seems there is a bug in validator component.
Steps to reproduce:
0. Open and run http://jsfiddle.net/Upw9j/2/
here's the code (some part is missing here due to SO limitations):
$(document).ready(function () {
var crudServiceBaseUrl = "http://demos.telerik.com/kendo-ui/service",
dataSource = new kendo.data.DataSource({
transport: {
read: {
url: crudServiceBaseUrl + "/Products",
dataType: "jsonp"
},
update: {
url: crudServiceBaseUrl + "/Products/Update",
dataType: "jsonp"
},
destroy: {
url: crudServiceBaseUrl + "/Products/Destroy",
dataType: "jsonp"
},
create: {
url: crudServiceBaseUrl + "/Products/Create",
dataType: "jsonp"
},
parameterMap: function (options, operation) {
if (operation !== "read" && options.models) {
return { models: kendo.stringify(options.models) };
}
}
},
batch: true,
pageSize: 20,
schema: {
model: {
id: "ProductID",
fields: {
ProductID: { editable: false, nullable: true },
ProductName: {
validation: {
required: true,
productnamevalidation: function (input) {
if (input.is("[name='ProductName']") && input.val() != "") {
input.attr("data-productnamevalidation-msg", "/^\d{1,}$/");
return /^\d{1,}$/.test(input.val());
}
return true;
}
}
},
UnitPrice: { type: "number", validation: { required: true, min: 1} },
Discontinued: { type: "boolean" },
UnitsInStock: { type: "number", validation: { min: 0, required: true} }
}
}
}
});
$("#grid").kendoGrid({
dataSource: dataSource,
pageable: true,
height: 430,
toolbar: ["create"],
columns: [
"ProductName",
{ field: "UnitPrice", title: "Unit Price", format: "{0:c}", width: "100px" },
{ field: "UnitsInStock", title: "Units In Stock", width: "100px" },
{ field: "Discontinued", width: "100px" },
{ command: ["edit", "destroy"], title: " ", width: "172px"}],
editable: "inline"
});
});
Click Edit at any row
Set the cursor on ProductName field, input "2s" (without quotes), press Tab
The tooltip will appear, saying "/^d{1,}$/" (it's a RE, which is matched against field value)
Press Shift+Tab, input "2" (w/o quotes), press Tab, message will disappear.
Repeat steps 3-4 several times. After 2-3 iterations you'll find that message doesn't disappear when field contains valid value. "Update" button behaves correctly.
Is it really a bug or am I doing something wrong? How to work it around?
Yes, this is a bug. I don't know where the official bug tracking page is, but this is a forum thread that details more precisely what's happening: Kendo UI Error on Grid Custom Validation
Basically, when the custom validation fails the input, the datasource model is not updated. So when you re-enter the same (and correct input), it checks against the last correct value, and because it's the same, the validation doesn't fire. In your case, you can verify that if you change the numbers everytime, it still works (2s -> 2 -> 2s -> 3 -> 2s -> 4 etc... this works)
You can also reproduce the custom validation bug right on their demo page. Change Chai to chai to Chai again and the message will still show.
Telerik hasn't fixed it yet and I'm not sure of any easy fixes. You can try to update the data model yourself in the validator function, but this is potentially bad as it gives the user the ability to save bad input into your back end.
Personally (and unfortunately), I just avoided custom validation altogether and ended up using server side validation.
I cannot get Kendo Grid to populate from server side data.
I have a grid builder function as as follows:
var build = function (carrier, date) {
var urlBase = 'my base url';
var datasource = new kendo.data.DataSource({
pageSize: 20,
serverPaging: true,
serverFiltering: true,
serverSorting: true,
schema: {
model: {
id: 'Id',
fields: {
StatementDate: { type: "string", editable: false },
CobDate: { type: "string", editable: false },
//lots more fields
Status: { type: "string", editable: false },
Matched: { type: "boolean", editable: true }
}
}
},
transport: {
read: function (options) {
var address = urlBase + '/' + carrier + '/' + date;
$.ajax({
url: address,
type: "POST",
data: JSON.stringify(options.data),
contentType: "application/json",
success: function (result) {
options.success(result);
},
error: function (result) {
options.error(result);
}
});
},
//update function omitted
parameterMap: function (data, operation) {
if (operation == "read") {
return JSON.stringify(data)
}
},
change: function (e) {
var data = this.data();
console.log(data.length); // displays "77"
}
}
});
return datasource;
};
return {
build: build
}
Grid Definition
elem.kendoGrid({
columns: [
{ field: "StatementDate", title: "State Date", width: 125 },
{ field: "CobDate", title: "COB Date", width: 100 },
//lots more fields
{ command: ["edit"], title: " ", width: "85px"}],
resizable: true,
sortable: true,
editable: "inline",
columnMenu: true,
filterable: true,
reorderable: true,
pageable: true,
selectable: "multiple",
change: this.onSelectedRecordChanged,
toolbar: kendo.template($('#' + templateName).html()),
scrollable: {
virtual: true
},
height: 800
});
I trigger the update via a button click. When I look at the response I see the data. Looks good but the grid will not show the data. It has previously worked fine when data was completely client side.
If I break point on the AJAX call back. I see the correct results.
The grid is bound with data bind. The datasource is a property on a viewmodel.
<div id="grid" data-bind="source: dataSource"></div>
At the start of the app. I create view model
var viewModel= kendo.observable(new GridViewModel(...
and bind
kendo.bind($('#grid'), viewModel);
If I look at the datasource attached to the grid, I see data for the page as expected
This has previously worked fine when data was client side.
I have tried using read() on datasource, and refresh() method on grid. Neither seems to work.
Example response content from server
{"Data":[{"Id": //lots more fields, 20 records],"Total":90375,"AggregateResults":null,"Errors":null}
Any help very much appreciated.
I found the cause in datasource schema missing
{ data: 'Data', total: 'Total' }
