Im trying to sort my datasource my multiple fields but it doesnt work.
Here's my code:
var dataSource = new kendo.data.DataSource({
transport: {
read: notifURL
},
pageSize: 30,
sort: [{ field: "ID", dir: "desc" },
{ field: "Time", dir: "desc" }]
});
The answer is here:
<script>
var dataSource = new kendo.data.DataSource({
data: [
{ name: "Tea", category: "Beverages" },
{ name: "Coffee", category: "Beverages" },
{ name: "Ham", category: "Food" }
],
sort: [
// sort by "category" in descending order and then by "name" in ascending order
{ field: "category", dir: "desc" },
{ field: "name", dir: "asc" }
]
});
dataSource.fetch(function(){
var data = dataSource.view();
console.log(data[1].name); // displays "Coffee"
});
</script>

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
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 can´t filter.

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.$filter) {
//my transformation
c = myTransformation;
return c;
} else{
return c; //not apply transformation loading the data
}
}
I'm adding and removing data to a Kendo dataSource. I wish to save it localStorage, and be able to read it again from localStorage.
Here I've attempted to use jStorage for the saving and loading of data.
How it's loaded:
if ($.jStorage.get('favoritter') != null) {
var datakilde_favoritter = $.jStorage.get('favoritter');
} else {
var data = [
{id: 5, name: "LINK ONE", url: "http://www.linkone.com" }
];
var datakilde_favoritter = new kendo.data.DataSource({
data: data,
sort: { field: "name", dir: "asc" }
});
}
How it's saved:
$.jStorage.set('favoritter', datakilde_favoritter);
Define your DataSource as:
var ds = new kendo.data.DataSource({
transport: {
read : function (op) {
var data = $.jStorage.get('favoritter');
if (!data) {
data = [
{id: 5, name: "LINK ONE", url: "http://www.linkone.com" }
];
}
op.success(data);
},
update : function (op) {
$.jStorage.set("favoritter", ds.data());
op.success(op.data);
},
destroy: function (op) {
console.log("destroy", ds.data());
$.jStorage.set("favoritter", ds.data());
op.success(op.data);
},
create : function (op) {
$.jStorage.set("favoritter", ds.data());
op.success(op.data);
}
},
sort : { field: "name", dir: "asc" },
pageSize : 10,
schema : {
model: {
id : "id",
fields: {
id : { type: 'number' },
name: { type: 'string' }
}
}
}
});
You might consider removing create and destroy if not needed.
And your grid would be something like:
var grid = $("#grid").kendoGrid({
dataSource: ds,
editable : "popup",
pageable : true,
toolbar : ["create"],
columns : [
{ command: ["edit", "destroy"], width: 100 },
{ field: "id", width: 90, title: "#" },
{ field: "name", width: 90, title: "URL Name" }
]
}).data("kendoGrid");
Basically when updating you need to invoke op.success with the data returned from the server. In your case since it is the browser itself, you don't need just to return the original data.
I referred Kendo articles and did goggling ,But I couldn't found any solution.
step 1:
Is it possible that when we are using common data source and binding the whole data to chart and grid with pagination this is to happen when the page is loading.
step 2:
later on based on the filter condition applied on grid the data in chart should change.
Any help or suggest me whether it is possible or not..
var common = new kendo.data.DataSource({
type : "odata",
transport: {
read: "http://demos.kendoui.com/service/Northwind.svc/Orders"
},
schema : {
model: {
fields: {
OrderDate: { type: "date" }
}
}
}
});
common.read();
var grid = $("#grid").kendoGrid({
dataSource: common,
pageSize : 10,
pageable : {
refresh : true,
pageSizes: [10, 20]
},
filterable:true,
columns : [
{
field : "OrderID",
filterable: false
},
"Freight",
{
field : "OrderDate",
title : "Order Date",
width : 100,
format: "{0:MM/dd/yyyy}",
filterable: true
},
{
field: "ShipName",
title: "Ship Name",
width: 200,
filterable: true
},
{
field: "ShipCity",
title: "Ship City",
filterable: true
}
]
}).data("kendoGrid");
$("#chart").kendoChart({
dataSource : common,
autoBind : false,
categoryAxis: {
field: "OrderID"
},
legend : {
position: "right", visible: true
},
seriesDefaults: { type: "area" },
series : [
{ field: "OrderDate", name: "OrderDate" },
{ field: "Freight", name: "Freight" },
{ field: "ShipVia", name: "ShipVia" }
],
valueAxis : [
{
name : "OrderID",
max : 5.0,
min : 0,
labels : {
format: "{0}"
},
tooltip: { visible: true }
}
]
});
Here is fiddle up to now I have tested with : http://jsfiddle.net/D3rSk/189/
The grid doesn't have a pageSize option. You need to set the page size in the data source configuration:
var common = new kendo.data.DataSource({
pageSize : 10,
type : "odata",
transport: {
read: "http://demos.kendoui.com/service/Northwind.svc/Orders"
},
schema : {
model: {
fields: {
OrderDate: { type: "date" }
}
}
}
});
Here is the updated jsFiddle: http://jsfiddle.net/D3rSk/192/
I am new on kendo UI framework. I am struggling with observable datasource with kendoGrid.
The problem is the table gets created but with empty data.
Here is the link http://jsfiddle.net/praveeny1986/Pf3TQ/5/
And the code :
var gridDataModel = kendo.data.Model.define({
fields: {
"Product": {
type: "string"
},
"Domain": {
type: "string"
},
"PercentPlan": {
type: "string"
},
"CWV": {
type: "string"
},
"Target": {
type: "string"
},
"Accuracy": {
type: "string"
}
}
});
var dataSource = new kendo.data.DataSource({data: tabledata1});
var gridModel = kendo.observable({
gridData: dataSource
});
kendo.bind($("#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.
