Is is possible to for the KendoUI Chart (Area) to have multiple data labels or even a concatenation of two? I need to display both a value and a percentage for each data point. Is this something that would need to be handled on the data source side or is it on the view?
Thanks for any help.
You can use templates to format both labels and tooltips; see labels.template and tooltip.template.
The key is to reference the Property you want using dataItem ex:
dataItem.TotalDollars
template: "${ category } - #= kendo.format('{0:C}', dataItem.TotalDollars)#"
The answer above wont really help unless you have a strong understanding of the Kendo UI framework. I was having a similar issue and before I found my answer I found this question. I circled back because the answer is simple and some simple example code is really simple. Lets save everyone some clicks.

I am currently working on a project for my company, where I need to plot highstock charts, which show energy-data of our main buildings.
Since it is live data, new datapoints come per Websocket every few-or-so seconds. However, the graph should only show one datapoint every hour. I wanted to clear this with the highstock dataGrouping, but it does not really work. It groups the points yes, but it still shows the „transmission“, the graph-line, between them. Thus making the whole graph completely irreadable.
In an other Version of the project, the graph only shows the latest datapoint of each group (as specified in the „approximate“ object in the chart options), but also does not start a new group after the chosen Interval runs through.
I've been sitting on this problem for about 3 days now and have not found any proper completely working solution yet.
Unfortunately, due company policy and due to hooks and components necessary, which are only used here in the company, I'm not able to give you a jsfilddle or similar, even though I'd really love to. What I can do is give you the config, mabye you find something wrong there?
const options = {
plotOptions: {
series: {
dataGrouping: {
anchor: 'end',
approximation: function (groupData: unknown[]) {
return groupData[groupData.length - 1];
},
enabled: true,
forced: true,
units: [['second', [15]]],
},
marker: {
enabled: false,
radius: 2.5,
},
pointInterval: minutesToMilliseconds(30),
pointStart: currentWeekTraversed?.[0]?.[0],
},
},
}
This would be the plotOptions.
If you need any more information, let me know. I'll see then, what and how I can send it to you.
Thank you for helping. ^^
This is example how dataGrouping works with live data,
try to recreate your case in addition or use another demo from official Highcharts React wrapper page.
rangeSelector: {
allButtonsEnabled: true,
buttons: [{
type: 'minute',
count: 15,
text: '15S',
preserveDataGrouping: true,
dataGrouping: {
forced: true,
units: [
['second', [15]]
]
}
}, {
type: 'hour',
count: 1,
text: '1M',
preserveDataGrouping: true,
dataGrouping: {
forced: true,
units: [
['minute', [1]]
]
}
}
},

here is my KendoGrid :
$scope.gridEltCompoOptions = {
dataSource: {
transport: {
...
},
schema: {
model: {
id: 'IdElement',
fields: {
GroupeActes: { defaultValue: { IdGroupeActes: null, Libelle: ' ' } }
}
}
}
},
sortable: true,
resizable: true,
filterable: {
mode: 'row'
},
columns: [{
field: 'GroupeActes',
title: "Groupe d'actes",
template: function (dataItem) {
return kendo.toString(dataItem.GroupeActes.Libelle);
}
}, ]
I want to filter my field 'GroupeActes' on the property Libelle (GroupeActes is an object), but actually the filter take the entire object.
When i try to filter, i have a Js Error
Uncaught TypeError: (d.GroupeActes || "").toLowerCase is not a function
The problem is clear, the filter is taking the entiere object, not the property Libelle.
i passed the last 4 hours to try all the solutions i found on google but nothing is working
my object GroupeActes is like this :
var GroupeActes = {
GroupeActes : {
Libelle : ""
}
}
there is two groupeActes level
I saw a post in 2015 of an Admin, saying this kind of filter isn't possible,
but i saw also this kind of solution :
https://docs.telerik.com/kendo-ui/knowledge-base/grid-filter-column-with-dropdownlist
(if(e.field == "Category" && e.filter !== null){) in the example
i tried to do something like : if field == "groupeActes" => so i want to filter on Libelle properties,
but i didn't success
Can someone help me please ?
thank you so much
Have you looked at this article: https://docs.telerik.com/kendo-ui/knowledge-base/enable-operations-for-object-column
I believe you can accomplish what you want by setting the column field to "GroupeActes.Libelle" instead of using a column template:
columns: [
{
field: 'GroupeActes.Libelle',
title: "Groupe d'actes",
},
],
See this DEMO:
I got this small but strange error while implementing kendo column filters. My filtering icon has an additional dot in IE. In all other browsers everything looks fine. I don't know how to delete or at least hide this small additional dot.
Here is the screenshot from IE:
and here is how it should look like:
I used a regular kendo filtering implementation, example of the code is below:
var MyGrid = function($div) {
var base = $div.data('baseurl');
var columns = [
{ field: 'userName', title: 'User Name'},
{ field: 'age', type:'number', title: 'Age' }];
grid($div, columns, {
datasource: datasource(base + '/double', ViewBackbone.options()),
options: {
filterable : {
extra: false,
operators: {
string: {
contains: "Contains",
startswith: "Starts with",
eq: "Equals"
},
number: {
eq: "Is equal",
gt: "Greater than",
lt: "Less than"
}
},
messages: {
info: "Choose an option",
filter:"Filter",
clear: "Clear"
}
},
}
});
};
The problem was solved by fixing the width property to the columns header. So in your css you have to specify the width to be more than 100%. I set up mine to be 115% and the dot disapeered.
I have a normal WCF service where there is a product that belongs to a department.
The URL to get a department of a given product would look like this:
http://localhost:49168/RapDataService.svc/Products(1000)/Department/Name
Using Razor I can have the foreignkey column that does what I want, but I can't find the syntax for JavaScript. I would assume something like this:
columns: [
{
field: "Department#Name",
filterable: false
},
But I can't find the correct syntax anywhere.
Found answer, just have to expand the datasource
type: "odata",
transport: {
read: {
url: "http://localhost:49168/RapDataService.svc/Products",
data: { $expand: "Department"}
}
},
And then the syntax I was looking for was the dot.
{
field: "Department.Name",
title: "Afdeling",
filterable: true
},
I'm using the latest version of kendoui and whenever I use the "is not equal to" or "does not contain" filter I get the following error:
Uncaught TypeError: Cannot read property 'length' of undefined
I'm using a server side datasource, all the other filters seem to work without issue.
Also, how do I specify a datetimepicker for a date column?
I've looked at the documentation and tried using:
filterable: {
ui: "datetimepicker"
}
But it never shows the datetimepicker.
Here is the code:
var dataSourceArguments = {
pageSize:10,
serverPaging:true,
serverFiltering:true,
serverSorting:true,
transport:{
read:{
url:$("#grid_order").attr('data-url'),
dataType:"json"
}
},
schema:{
total:"count",
data:'fields'
},
sort:{'field':'order_date', dir:'desc'}
};
var ds2 = new kendo.data.DataSource(dataSourceArguments);
$("#grid_order").kendoGrid({
dataSource:ds2,
groupable:true,
scrollable:true,
sortable:true,
pageable:true,
columns:[
{
field:'order_date',
title:'Order Date',
width:150,
filterable: {
ui: "datetimepicker"
}
},
{
field:"reference",
title:'Reference',
width:120,
encoded:false
},
{
field:"client__company",
title:'Client',
encoded:false
},
{
field:"grand_total",
title:'Total',
width:100
},
{
field:'status',
title:'Status',
width:120,
encoded:false
},
{
field:'actions',
width:200,
title:'Actions',
filterable:false,
encoded:false,
sortable:false
}
],
filterable:true
});
UPDATE: I managed to get the datepicker working however whenever I choose the date, and click filter it filters but the date I've chosen dissapears from the field.
Add the order_date to the scheme from the data source, and the data type of the field to date.
