Kendo UI Grid not loading data from datasource - kendo-ui

I am new on kendo UI framework. I am struggling with observable datasource with kendoGrid.
The problem is the table gets created but with empty data.
Here is the link http://jsfiddle.net/praveeny1986/Pf3TQ/5/
And the code :
var gridDataModel = kendo.data.Model.define({
fields: {
"Product": {
type: "string"
},
"Domain": {
type: "string"
},
"PercentPlan": {
type: "string"
},
"CWV": {
type: "string"
},
"Target": {
type: "string"
},
"Accuracy": {
type: "string"
}
}
});
var dataSource = new kendo.data.DataSource({data: tabledata1});
var gridModel = kendo.observable({
gridData: dataSource
});
kendo.bind($("#chart"),gridModel);
$("#chart").kendoGrid({
scrollable:false,
dataSource:gridModel.get('gridData'),
height:600,
autoBind:true,
columns:[
{
field: "Product",
title: "Product"
},
{
field: "Domain",
title: "Sales Domain"
},
{
field: "PercentPlan",
title: "% to Plan"
},
{
field: "CWV",
title: "CWV"
},
{
field: "Target",
title: "Target"
},
{
field: "Accuracy",
title: "Accuracy"
}]
});
var tabledata1 = [
{
Product:"mobile",
Domain:"SMARTPHONES-EAST",
PercentPlan:"95",
CWV:"160",
Target:"200",
Accuracy:"9"
},
{
Product:"mobile",
Domain:2,
PercentPlan:"80",
CWV:"160",
Target:"200",
Accuracy:"8.5"
},
{
Product:"mobile",
Domain:3,
PercentPlan:"75",
CWV:"150",
Target:"200",
Accuracy:"8"
},
{
Product:"mobile",
Domain:4,
PercentPlan:"60",
CWV:"120",
Target:"200",
Accuracy:"6"
},
{
Product:"mobile",
Domain:5,
PercentPlan:"50",
CWV:"150",
Target:"300",
Accuracy:"5"
}
];
Please suggest what i am doing wrong ?
Thanks in advance

Your table data is undefined at the time that you create and bind the datasource.
var dataSource = new kendo.data.DataSource({data: tabledata1});
var tabledata1 = [ ... ];
Move the declaration of tabledata1 to before creating the datasource.
See this updated fiddle.

Kendo Grid disable field during Edit mode

Using kendo grid edit event I want to disable field name and id during Edit mode. I manage to disable id by following this example here. But went I try to disable name seem it not working, any thought how to do this?
WORKING DEMO IN DOJO
$("#grid").kendoGrid({
columns: [
{ field: "id" },
{ field: "name" },
{ field: "age" },
{ command: "edit" }
],
dataSource: {
data: [
{ id: 1, name: "Jane Doe", age: 30 },
{ id: 2, name: "John Doe", age: 33 }
],
schema: {
model: {
id: "id",
fields: {
"id": { type: "number" },
"name": { type: "string" }
}
}
}
},
editable: "inline",
toolbar:["create"],
edit: function(e) {
if (!e.model.isNew()) {
var numeric = e.container.find("input[name=id]").data("kendoNumericTextBox");
numeric.enable(false);
//var x = e.container.find("input[name=name]").data("kendoTextBox");
//x.enable(false);
//$("input[name=name]").prop("disabled", true).addClass("k-state-disabled");
//$("input[name=name]").editable = false;
}
}
});
by using editable function i created this
function isEditable(e){
var dataSource = $("#grid").data("kendoGrid").dataSource;
return (e.id == null || e.id == '');
}
and add this into the grid > column
columns: [
{ field: "id", editable: isEditable },
{ field: "name", editable: isEditable },
{ field: "age" },
{ command: "edit" }
],
Full working demo is here

Kendo Grid Server side filtering with a array type column

I have this kendo grid blinded to my web service. One of the columns has a custom filter with a kendo multiselector array so the client can choose multiple ItemTypes. The grid is displaying data correctly but my costume filters are not working for this particular column. I got this error from the service: "A binary operator with incompatible types was detected. Found operand types 'Telerik.Sitefinity.DynamicTypes.Model.ClinicFinder.Clinic.ItemType.ItemType' and 'Edm.Int32' for operator kind 'Equal'."
My grid definition
$("#grid").kendoGrid({
dataSource: {
type: "odata-v4",
transport: {
read: {
url: function () {
return "//myservice/api/clinics?$select=Id,Title,Address,ItemType,productsystems&top=20";
}
}
},
schema: {
model: {
fields: {
Title: { type: "string" },
CountryCode: { type: "string" },
Street: { type: "string" },
City: { type: "string" },
Zip: { type: "string" },
ItemType: { type: "" }
}
}
},
serverPaging: true,
serverFiltering: true,
serverSorting: false,
pageSize: 20
},
pageable: true,
filterable: {
mode: "row",
extra: false,
showOperators: false,
operators: {
string: {
contains: "contains"
}
}
},
sortable: false,
columns: [
{ field: "Title", title: "Clinic" },
{ field: "CountryCode", title: "Country" },
{ field: "Street", title: "Address" },
{ field: "City", title: "City" },
{ field: "Zip", title: "Zip", filterable: false },
{ field: "ItemType", title: "Clinic Type", filterable: { multi: true } }
],
rowTemplate: kendo.template($("#template").html())
});
My Filter function
function filterByclinicCategory() {
var filter = { logic: "or", filters: [] };
var grid = $('#grid').data('kendoGrid');
var filterValue = $("#clinicTypeFilter").data("kendoMultiSelect").value();
var clinicCode = [];
if (filterValue.length > 0) {
$.each(filterValue, function (i, v) {
clinicCode.push(convertClinicTypesInCodes(v));
filter.filters.push({
field: "ItemType", operator: "eq", value: clinicCode, logic: "or"
});
grid.dataSource.filter(filter);
});
} else {
$("#grid").data("kendoGrid").dataSource.filter({});
}
}
ItemType is the column I canĀ“t filter.
My webservice data

}
}
]
}
I manage to fix it using parameterMap https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/configuration/transport.parametermap.
I add a parameterMap: functiondata, type) function, with that I was able to intercept and change the call made by the filters.
parameterMap: function (data, type) {
var c = kendo.data.transports["odata-v4"].parameterMap(data, type);
if (c.$filter) {
//my transformation
c = myTransformation;
return c;
} else{
return c; //not apply transformation loading the data
}
}

Kendo Grid doesn't show any data despite having data within DataSource

So, I'm trying to make a readyonly grid with kendo that shows data, but whatever I do, the data does not get shown.
The grid looks like this
And here's the code:
$("#Materials")
.kendoGrid({
dataSource: {
data: [],
schema: {
model: {
id: "ID",
fields: {
ID: { type: "number", editable: false },
Code: { type: "string", editable: false },
Name: { type: "string", editable: false },
ExtDeviceCode: { type: "string", editable: false , nullable: true },
BaseUomLOVString: { type: "string", editable: false }
}
}
},
pageSize: 20
},
filterable: {
extra: true
},
pageable: true,
columns: [
{ field: "Code", title:"Code"},
{ field: "Name", title: "Name"},
{ field: "ExtDeviceCode", title:"External device code"},
{ field: "BaseUomLOVString", title: "UnitsOfMeasure" }
],
editable: false
});
This makes an empty grid with no data, which I later on fill with an Ajax call. As you can see from above picture, the grid contains the data but does not display it. The data inside the dataSource looks like this. or as Json:
[{
"ID": 21150,
"Code": "3",
"ExtDeviceCode": null,
"Name": "Avio benzin",
"BaseUomLOVString": "Kilogram"
}, {
"ID": 21400,
"Code": "5003",
"ExtDeviceCode": null,
"Name": "Bencin 95",
"BaseUomLOVString": "Litre"
}]
EDIT 1: I'm filling the data with an Ajax call like this:
$.ajax({
url: '#SimpleUrlHelper.UrlObjectToRoot(Url)/FuelPointMaterialTankMask/LookupMaterials',
data: {
//Send list of IDs
'materialIDs': materialList
},
type: "POST",
success: function (response) {
var tmp = [];
if (typeof response !== "undefined" &&
response !== null) {
response.forEach(function(item) {
tmp.push(item);
});
}
grid = $("#Materials").data("kendoGrid");
originalMaterialDataSource = grid.dataSource;
originalMaterialDataSource.data(tmp);
originalMaterialDataSource._destroyed = [];
originalMaterialDataSource.pageSize(pageSize);
originalMaterialDataSource.page(1);
originalMaterialDataSource._total = tmp.length;
grid.pager.refresh();
}
});
You can set your data in your dataSource after your ajax call.
var dataArray = [{
"ID": 21150,
"Code": "3",
"ExtDeviceCode": null,
"Name": "Avio benzin",
"BaseUomLOVString": "Kilogram"
}, {
"ID": 21400,
"Code": "5003",
"ExtDeviceCode": null,
"Name": "Bencin 95",
"BaseUomLOVString": "Litre"
}];
Use .data() to set:
$("#Materials").data('kendoGrid').dataSource.data(dataArray );
Okay so after days of trying to figure out what was wrong I finally found the answer.
Somewhere along the lines I had:
var grids = $('.k-grid');
for (var i = 0; i < grids.length; i++) {
....
grid.dataSource.filter().filters[0] = {
logic: "or",
filters: filters
}
....
So basically I was putting filters on all grids without excluding this one, which was just a bug from my part.

KendoUI Grid Signalr Error

I am receiving the error "Maximum call stack size exceeded" while trying to bind Signalr data to the KendoUI grid (v2014.1 416).
Here is my current code:
var epConnection = $.hubConnection();
var hub = epConnection.createHubProxy("EventsPendingHub");
var hubStart = epConnection.start();
$('#tblEventsPending').kendoGrid({
sortable: true,
columns: [
{ field: "EventNum" },
{ field: "Area" },
{ field: "Zone" },
{ field: "Priority" },
{ field: "Type" },
{ field: "TIQ" },
{ field: "Location" },
{ field: "Apt"}
],
dataSource: {
type: "signalr",
autoSync: true,
schema: {
model: {
id: "EventNum",
fields: {
"EventNum": { type: "string" },
"Area": { type: "string" },
"Zone": { type: "string" },
"Priority": { type: "string" },
"Type": { type: "string" },
"TIQ": { type: "string" },
"Location": { type: "string" },
"Apt": {type: "string"}
}
}
},
sort: [
{ field: "Priority", dir: "desc"},
{ field: "TIQ", dir: "desc"}
],
transport: {
signalr: {
promise: hubStart,
hub: hub,
server: {
read: "read",
update: "update",
destroy: "destroy",
create: "create"
},
client: {
read: "read",
update: "update",
destroy: "destroy",
create: "create"
}
}
}
}
});
Hub Code:
[HubName("EventsPendingHub")]
public class EventsPendingHub : Hub
{
private readonly EventsPending _eventsPending;
public EventsPendingHub() : this(EventsPending.Instance) {}
public EventsPendingHub(EventsPending eventsPending)
{
_eventsPending = eventsPending;
}
public IEnumerable<EventPending> GetAllEventsPending()
{
return _eventsPending.GetAllEventsPending();
}
}
Startup.cs:
[assembly: OwinStartup(typeof(CADView.Startup))]
namespace CADView
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
var hubConfiguration = new HubConfiguration();
hubConfiguration.EnableDetailedErrors = true;
app.MapSignalR(hubConfiguration);
}
}
}
The error is being thrown at the client by jQuery...the last line from below is repeated 30+ times.
Uncaught RangeError: Maximum call stack size exceeded
o.extend.isPlainObject jquery-2.1.0.min.js?hash=2258a75c-c461-4821-2436-dfdf3af9bffe:2
o.extend.o.fn.extend jquery-2.1.0.min.js?hash=2258a75c-c461-4821-2436-dfdf3af9bffe:2
I have the similar problem with you and i find out that kendo ui is not compatible with higher version of jQuery.
ex:-jquery-2.1.0.min.js
it is compatible with jquery-1.9.1.min.js
try this you will get rid of this problem.

Display the popup view when the filtering is under process

In my group's project, we had a one grid and export button. We came across an issue which is that when exopt the data in excel format fiddle: http://jsfiddle.net/SZBrt/11/ need to display the pop up message stating that 'The data is getting filtered' to be displayed so that the we can know the filtering is under process. I appreciate your help in advance.
And My Code:
var grid = $("#grid").kendoGrid({
dataSource: {
type : "odata",
transport : {
read: "http://demos.kendoui.com/service/Northwind.svc/Orders"
},
schema : {
model: {
fields: {
OrderID : { type: "number" },
Freight : { type: "number" },
ShipName : { type: "string" },
OrderDate: { type: "date" },
ShipCity : { type: "string" }
}
}
},
pageSize : 10
},
filterable: true,
sortable : true,
pageable : true,
columns : [
{
field : "OrderID",
filterable: false
},
"Freight",
{
field : "OrderDate",
title : "Order Date",
width : 100,
format: "{0:MM/dd/yyyy}"
},
{
field: "ShipName",
title: "Ship Name",
width: 200
},
{
field: "ShipCity",
title: "Ship City"
}
]
}).data("kendoGrid");
Add to the DataSource definition an event handler for requestStart and requestEnd.
dataSource: {
requestStart : function() {
// Add code for displaying your own "loading" message
},
requestEnd: function() {
// Add code for hiding your own "loading" message
},
type : "odata",
transport : {
read: "http://demos.kendoui.com/service/Northwind.svc/Orders"
},
schema : {
model: {
fields: {
OrderID : { type: "number" },
Freight : { type: "number" },
ShipName : { type: "string" },
OrderDate: { type: "date" },
ShipCity : { type: "string" }
}
}
},
pageSize : 10
},
You did not specify how that Loading message looks like, it might be as simple as adding / removing visibility:
requestStart: function () {
$("#loading-msg").css("visibility", "visible");
},
requestEnd: function () {
$("#loading-msg").css("visibility", "hidden");
},
or open / close a window:
requestStart: function () {
$("#loading-msg").data("kendoWindow").center().open();
},
requestEnd: function () {
$("#loading-msg").data("kendoWindow").close();
},
