I am updating Kendo-grid when the selected value in option HTML element is changed. But when I try to update the value in the grid inline in the browser's console is printed "kendo.web.min.js:13 Uncaught TypeError: Cannot read property 'data' of undefined".
What Did I wrong?
< script >
$(document).ready(function() {
// on changing zone option selector
$('#SelectProviderZoneForPrices').change(function (e) {
var zoneId = $(this).val();
var productId = $('#SelectProviderForPrices').val();

// loads prices

I found the problem. I was removed the id property in my datasource-model of the grid and that caused my problems. I don't know why it is so big deal - especially when I could have objects without ID. But now it is fine.
id: "ProviderWeightsId",
fields: {
ProviderWeightsId: { editable: false, visible: false, type: "number" },
ZoneId: { editable: false, visible: false, type: "number" },
ZoneName: { editable: false, visible: false, type: "string" },
WeightFrom: { editable: false, visible: true, type: "number" },
WeightTo: { editable: false, visible: true, type: "number" },
Price: { editable: true, visible: true, type: "number" }
}
You are not passing data to the loadPrices function.
$('#SelectProviderZoneForPrices').change(function (e) {
var zoneId = $(this).val();
var productId = $('#SelectProviderForPrices').val();
$.ajax({
type: "GET",
url: "#Html.Raw(Url.Action("LoadZoneWeights", "ShippingZonableByWeight"))",
success: function (data) {
loadPrices(data); //pass data to loadPrices function
}
dataType: 'json',
data: { ProviderId: productId, ZoneId: zoneId }});
});
Update:
Try this :
public ActionResult LoadZoneWeights(int ProviderId, int ZoneId)
{
var zoneWeights = _shippingService.GetZonesWithWeights(ProviderId, ZoneId);
return Json(zoneWeights , JsonRequestBehavior.AllowGet);
}
and
schema: {
data: function(response) {
return response.data;
}
}

today i'm trying to implement a kendo gridview to my website, actually i'm using a webservice that give me a JSON Result.
This is the result:
[{"IdComponente":"8","NoParte":"12","Descripcion":"Componente A","CostoUnitario":"0.12"},{"IdComponente":"9","NoParte":"123","Descripcion":"Componente B","CostoUnitario":"0.23"},{"IdComponente":"10","NoParte":"1234","Descripcion":"Componente C","CostoUnitario":"0.54"},{"IdComponente":"11","NoParte":"12345","Descripcion":"Componente D","CostoUnitario":"0.90"},{"IdComponente":"12","NoParte":"123456","Descripcion":"Componente E","CostoUnitario":"1.25"},{"IdComponente":"13","NoParte":"1234567","Descripcion":"Componente F","CostoUnitario":"0.12"},{"IdComponente":"14","NoParte":"12345678","Descripcion":"Componente G","CostoUnitario":"0.12"},{"IdComponente":"16","NoParte":"123456789","Descripcion":"Componente H","CostoUnitario":"0.98"}]
And i'm using this script, the problem is that i don't get any error in the console, but it doesn't show me the information in the grid.
So, i don't know why, because the json result its okay..
<script>
$(document).ready(function () {
$.ajax({
type: "POST",
url: "WSComponentes.asmx/obtenerComponentes",
data: '',
contentType: "application/json; charset=utf-8",
dataType: "json", // dataType is json format
success: function OnSuccess(response) {
cargarGrid(response);
},
error: function onError(error) {
console.log(error.d);
},
});
});
function cargarGrid(datos) {
console.log(datos);
$("#grid").kendoGrid({
dataSource: {
dataType: 'json',
data: datos,
schema: {
data: "d",
type: "json",
model: {
fields: {
IdComponente: { editable: false, type: "string" },
NoParte: { editable: false, type: "string" },
Descripcion: { editable: false, type: "string" },
CostoUnitario: { editable: false, type: "string" }
}
}
},
pageSize: 10
},
height: 550,
groupable: true,
sortable: true,
pageable: {
refresh: true,
pageSizes: true,
buttonCount: 5
},
columns: [{
field: "IdComponente",
title: "IdComponente",
}, {
field: "NoParte",
title: "NoParte"
}, {
field: "Descripcion",
title: "Descripcion"
}, {
field: "CostoUnitario",
title: "CostoUnitario",
}
]
});
}
</script>
You're not far away with what you have.. You need to declare a kendo.data.DataSource:
var dataSource = new kendo.data.DataSource({
dataType: 'json',
data: datos,
schema: {
model: {
fields: {
IdComponente: { editable: false, type: "string" },
NoParte: { editable: false, type: "string" },
Descripcion: { editable: false, type: "string" },
CostoUnitario: { editable: false, type: "string" }
}
}
},
pageSize: 10
});
Which is then used in your grid declaration like so:
$("#grid").kendoGrid({
dataSource: dataSource, ....
Here is a Dojo example to demonstrate implementation changes required.
I'm using a kendo grid on a edit modal. When the modal pops up i need to check the specific rows. this my kendo grid.
function LoadControllerGrid(list) {
var ListofrowIds = list
$("#controllerGrid1").kendoGrid({
dataSource: {
type: "json",
// contentType: "application/json; charset=utf-8",
transport: {
read: {
url: "#Html.Raw(Url.Action("GetControllerList", "Account"))",
type: "POST",
dataType: "json"
},
},
schema: {
model: {
id: "UserId",
fields: {
'Id': { type: "string" },
'Name': { type: "string" },
'Description': { type: "string" },
'URL': { type: "string" },
},
},
data: 'data',
total: 'TotalCount'
},
complete: function (jqXHR, textStatus) {
// HidePageLoader();
},
pageSize: 5,
serverPaging: true,
serverSorting: true,
serverFiltering: true,
columnMenu: true
},
height: 300,
groupable: false,
sortable: true,
filterable: true,
pageable: {
refresh: true,
pageSizes: 5000
},
columns: [{ template: '<input type="checkbox" class="checkbox" />', width: "35px" },
{ field: "Description", title: "Actions" }, ]
});
}
I pass the ids of specific rows that need to be checked to the function. kendo grid above display the all the rows.how can i check the check boxes of those particular rows.
I am create one sample application and use kendo-ui inline editing grid.
Problem is: not come date field value in action controller.
View page Code is:
<script type="text/javascript">
$(document).ready(function () {
$("#grid").kendoGrid({
dataSource: {
type: "json",
transport: {
read: {
url: "#Html.Raw(Url.Action("CriticalDateList", "Home"))",
type: "POST",
dataType: "json"
},
create: {
url: "#Html.Raw(Url.Action("InsertCriticalDate", "Home"))",
type: 'POST',
dataType: "json"
},
},
change: function (e) {
if (e.action == "itemchange") {
e.items[0].dirtyFields = e.items[0].dirtyFields || {};
e.items[0].dirtyFields[e.field] = true;
}
},
batch: true,
schema: {
data: "Data",
total: "Total",
errors: "Errors",
model: {
id:"Id",
fields: {
Id: { editable: false},
Date: { editable: true, type: "date" },
}
}
},
error: function (e) {
//display_kendoui_grid_error(e);
this.cancelChanges();
},
pageSize:5,
serverPaging: true,
serverFiltering: true,
serverSorting: true
},
pageable: true,
height: 500,
toolbar: ["create"],
columns: [
{field: "Date", title: "Date", format: "{0:dd-MMM-yyyy hh:mm:ss tt}", parseFormats: ["yyyy-MM-dd'T'HH:mm:ss.zz"], width: "130px"},
{ command: ["edit", "destroy"], title: "Action", width: "250px" }],
editable: "inline"
});
Action Code is:
public ActionResult InsertCriticalDate(CriticalDateModels model)
{
return null;
}
output is.
And in my action i am getting different date.
I need to pass an additional parameter along with my grids datasources create routine but I am having trouble getting it to work.
I have tried:
$('#contactPhonesGrid').data("kendoGrid").dataSource.dataItem.set('phoneId', phoneId)
but this gives me the error Cannot read property 'set' of undefined.
Code for my grid:
function contactPhoneGrid() {
var contactPhoneGrid = $('#contactPhonesGrid').kendoGrid({
dataSource: {
pageSize: 25,
serverSorting: false,
serverFiltering: true,
sort: {
field: "ref",
dir: "asc"
},
transport: {
read: {
url: ROOT + 'Contact/contactPhoneGrid',
dataType: 'json',
type: 'POST'
},
create: {
url: ROOT + 'Contact/createContactPhone',
type: 'POST'
},
update: {
url: ROOT+'Contact/updateContactPhone',
dataType: 'json',
type: 'POST'
},
destroy: {
url: ROOT+'Contact/deleteContactPhone',
dataType: 'json',
type: 'POST'
}
},
error: function(e) {
alert(e.errorThrown + "\n" + e.status + "\n" + e.xhr.responseText);
},
schema: {
data: "data",
model: {
id: 'phoneId',
fields: {
phoneId: {
type: 'number'
},
type: {
type: 'string',
editable: true
},
tel: {
type: 'string',
editable: true
},
typeId: {
type: 'number',
editable: true
}
}
}
}
},
autoBind: false,
columns: [
{
field: 'phoneId',
headerTemplate: '<b>Phone Id</b>',
filterable: false,
width: '50px',
hidden: true
},
{
field: 'type',
headerTemplate: '<b>Type</b>',
filterable: false,
editor: phoneTypeEditor,
width: '80px',
// template: '#=type#'
},
{
field: 'tel',
headerTemplate: '<b>Number</b>',
filterable: false,
}
],
edit: function(e) {
var ddl = e.container.find('[data-role=dropdownlist]').data('kendoDropDownList');
if (ddl) {
ddl.open();
}
},
height: '75',
filterable: true,
editable: true,
sortable: true,
scrollable: true
}).data("kendoGrid");
}
dataItem is a method so you should not use it as:
$('#contactPhonesGrid').data("kendoGrid").dataSource.dataItem
but as:
$('#contactPhonesGrid').data("kendoGrid").dataSource.dataItem(something here)
See documentation here : http://docs.telerik.com/kendo-ui/api/web/grid#methods-dataItem
I'm using a KendoUI Grid to do in line batch editing. I'd like to display to the user a message upon successfully saving the changes. How do I do this?
My Mark-UP:
<div id="employeeGoalsGrid"></div>
My Javascript:
var goalsDataSource = new kendo.data.DataSource({
transport: {
read: {
url: '/MVC/ResearcherPoints/GetEmployeeResearchers',
type: 'POST',
contentType: 'application/json'
},
update: {
url: '/MVC/ResearcherPoints/UpdateEmployeeGoal',
type: 'POST',
contentType: 'application/json'
//dataType: "jsonp"
},
parameterMap: function (options, type) {
debugger;
$.extend(options, { ID: options.id });
return JSON.stringify(options);
}
},
batch: false,
schema: {
model: {
id: 'ID',
fields: {
id: { editable: false, nullable: false },
FirstName: { editable: false, nullable: true },
LastName: { editable: false, nullable: true },
Title: { editable: false, nullable: true },
TeamName: { editable: false, nullable: true },
PointsGoal: { type: "number", nullable: true, validation: { required: false, min: 1 } }
}
}
},
sortable: true,
filterable: true,
columnMenu: true
});
$('#employeeGoalsGrid').kendoGrid({
dataSource: goalsDataSource,
navigatable: true,
sortable: true,
resizable: true,
toolbar: ["save", "cancel"],
columns: [
{ field: "FirstName", title: "First Name", width: 200},
{ field: "LastName", title: "Last Name", width: 200 },
{ field: "Title", title: "Title", width: 200 },
{ field: "TeamName", title: "Team", width: 200 },
{ field: "PointsGoal", title: "Goal", width: 200 }],
editable: true,
filterable: true,
});
Rodney, what about taking advantage of the complete event. It is bit dirty I agree, but I never managed to make Kendo success event work (not sure if anyone ever managed to - kendo ?).
update: {
url: '/MVC/ResearcherPoints/UpdateEmployeeGoal',
type: 'POST',
contentType: 'application/json',
complete: function (jqXhr, textStatus) {
if (textStatus == 'success') {
var result = jQuery.parseJSON(jqXhr.responseText);
// read your result
// open your dialog
}
}
},
You should use the sync event of the dataSource.
var goalsDataSource = new kendo.data.DataSource({
sync: function(e){
alert('Synchronization has completed! Your changes are saved!')
}
//...
