I'm trying to enable some operations on my grid such as grouping, filtering and sorting, individually they works as shown in the docs but there is no an example of those functionality working together.
By myself I was able to combine sorting and filtering but grouping does not work when i'm adding it as it shown in the docs. look at at my code
<template>
<div>
<Grid :style="{height: '100%'}"
ref="grid"
:data-items="getData"
:resizable="true"
:reorderable="true"
#columnreorder="columnReorder"
:filterable="true"
:filter="filter"
#filterchange="filterChange"
:sortable="true"
:sort= "sort"
#sortchange="sortChangeHandler"
:groupable="true"
:group= "group"
#dataStateChange="dataStateChange"
:columns="columns">
</Grid>
</div>
</template>
<script>
export default {
data() {
return {
items: [],
editID: null,
columns: [
{ field: 'AbsenceEmployeID', filterable:false, editable: false, title: '#'},
{ field: 'Employe', title: 'Employer', cell: DropDownEmployes},
{ field: 'Remarque', title: 'Remarque'},
{ field: 'Type', title: 'Type', cell: DropDownTypes},
{ field: 'CreatedDate', filter:'date', editable: false, editor: 'date', title: 'créé le', format: '{0:d}'},
{ title: 'Actions', filterable:false, cell: CommandCell}
],
filter: {
logic: "and",
filters: []
},
sort: [
{ field: 'CreatedDate', dir: 'desc' }
],
group: [],
gridData: []
}
}
mounted() {
this.loadItems()
},
computed: {
absencesList() {
return this.items.map((item) => Object.assign({ inEdit: item.AbsenceEmployeID === this.editID}, item));
},
getData() {
return orderBy(filterBy(this.absencesList, this.filter), this.sort);
},
...mapState({
absences: state => state.absences.absences
})
}
methods: {
loadItems () {
this.$store.dispatch('absences/getAbsences')
.then(resp => {
this.items = this.absences.map(item => item)
})
},
filterChange: function(ev) {
this.filter = ev.filter;
},
columnReorder: function(options) {
this.columns = options.columns;
},
sortChangeHandler: function(e) {
this.sort = e.sort;
},
// the following is for grouping but not yet used, read more
groupedData: function () {
this.gridData = process(this.getData, {group: this.group});
},
createAppState: function(dataState) {
this.group = dataState.group;
this.groupedData();
},
dataStateChange: function (event) {
this.createAppState(event.data);
},
}
}
</script>
The last three methods are not used yet, so filtering and sorting is working perfectly as of now. then in other to enable grouping I want to replace :data-items="getData" by :data-items="gridData" and run this.groupedData() method after the items are loaded but grouping doesn't work.
I think everything should be handle by the dataStateChange event and process() function but I also tried but without success
If you define the filterchange and sortchange events they are being triggered for filter and sort and you will have to updated data in their handlers. If you rather want to use datastatechage event for all the changes you have to remove the filterchange and sortchange events and the datastatechage event will be triggered instead of them. In this case you will have to update the data in its handler.
You can use the process method of #progress/kendo-data-query by passing the respective parameter each data change that is needed as in the example below:
const result = process(data, {
skip: 10,
take: 20,
group: [{
field: 'category.categoryName',
aggregates: [
{ aggregate: "sum", field: "unitPrice" },
{ aggregate: "sum", field: "unitsInStock" }
]
}],
sort: [{ field: 'productName', dir: 'desc' }],
filter: {
logic: "or",
filters: [
{ field: "discontinued", operator: "eq", value: true },
{ field: "unitPrice", operator: "lt", value: 22 }
]
}
});
Hers is a sample stackblitz example where such example is working correctly - https://stackblitz.com/edit/3ssy1k?file=index.html
You need to implement the groupchange method to handle Grouping
I prefer to use process from #progress/kendo-data-query
The following is a complete example of this
<template>
<Grid :style="{height: height}"
:data-items="gridData"
:skip="skip"
:take="take"
:total="total"
:pageable="pageable"
:page-size="pageSize"
:filterable="true"
:filter="filter"
:groupable="true"
:group="group"
:sortable="true"
:sort="sort"
:columns="columns"
#sortchange="sortChangeHandler"
#pagechange="pageChangeHandler"
#filterchange="filterChangeHandler"
#groupchange="groupChangeHandler"
/>
</template>
<script>
import '#progress/kendo-theme-default/dist/all.css';
import { Grid } from '#progress/kendo-vue-grid';
import { process } from '#progress/kendo-data-query';
const sampleProducts = [
{
'ProductID': 1,
'ProductName': 'Chai',
'UnitPrice': 18,
'Discontinued': false,
},
{
'ProductID': 2,
'ProductName': 'Chang',
'UnitPrice': 19,
'Discontinued': false,
},
{
'ProductID': 3,
'ProductName': 'Aniseed Syrup',
'UnitPrice': 10,
'Discontinued': false,
},
{
'ProductID': 4,
'ProductName': "Chef Anton's Cajun Seasoning",
'UnitPrice': 22,
'Discontinued': false,
},
];
export default {
components: {
Grid,
},
data () {
return {
gridData: sampleProducts,
filter: {
logic: 'and',
filters: [],
},
skip: 0,
take: 10,
pageSize: 5,
pageable: {
buttonCount: 5,

},
sort: [],
group: [],
columns: [
{ field: 'ProductID', filterable: false, title: 'Product ID', width: '130px' },
{ field: 'ProductName', title: 'Product Name' },
{ field: 'UnitPrice', filter: 'numeric', title: 'Unit Price' },
{ field: 'Discontinued', filter: 'boolean', title: 'Discontinued' },
],
};
},
computed: {
total () {
return this.gridData ? this.gridData.length : 0;
},
},
mounted () {
this.getData();
},
methods: {
getData: function () {
this.gridData = process(sampleProducts,
{
skip: this.skip,
take: this.take,
group: this.group,
sort: this.sort,
filter: this.filter,
});
},
// ------------------Sorting------------------
sortChangeHandler: function (event) {
this.sort = event.sort;
this.getData();
},
// ------------------Paging------------------
pageChangeHandler: function (event) {
this.skip = event.page.skip;
this.take = event.page.take;
this.getData();
},
// ------------------Filter------------------
filterChangeHandler: function (event) {
this.filter = event.filter;
this.getData();
},
// ------------------Grouping------------------
groupChangeHandler: function (event) {
this.group = event.group;
this.getData();
},
},
};

I am working on a project in which I need to display List of objects in Kendo Grid.
below is the code for data binding.
$("#GridProperty").kendoGrid({
dataSource: {
transport: {
read: {
dataType: "json",
url: $_BindPropertyData,
data: { "LegalEntityId": LegalEntityId, "DatasetId": DatasetId },
async: true,
}
},
schema: {
model: {
fields: {
GeoId: { type: "int" },
GeoDescription: { type: "string" },
GeoAbbreviation: { type: "string" },
//ComponentDesc: { type: "string", from: "CompModelList.ComponentDesc" },
Id: { type: "int" },
Amount1: { type: "decimal", from: "CompModelList.SaDataModel.Amount1" },
Amount2: { type: "decimal"}
//lstcompModel: {type: ""}
}
}
},
},
noRecords: {
template: "<p style='margin-top:5px;'>There are currently no items available<p>"
},
height: 525,
reorderable: true,
groupable: true,
sortable: true,
filterable: true,
resizable: true,
columnMenu: true,
selectable: "row",
dataBound: function () {
},
columns: Columns
});
Description :
I am returning list of objects as json from my Action . but i am not able to bind the list of objects in kendo grid.
I am breaking my head for last four days. Please help.
Thanks
This is my JavaScript code. My table id is tblEmployee.
$(document).ready(function (){
$('#tblEmployee').DataTable({
ajax: {
"url": "http://localhost:57507/api/Employee/Get",
"dataSrc": ""
},
columns : [{ data: 'Employee_Id' }, { data: 'Project_Id' }, { data: 'Grade_Id' }, { data: 'Site_Id' },{ data: 'Location_Id' },{ data: 'StartDate' }, { data: 'EndDate' }, { data: 'BillRate' }, { data: 'Role' },
]
});
});
This is the data from my database which the web API calls:
This is because you are setting the dataSrc = "" . As per data-tables docs dataSrc should be set to empty string if you are reading via ajax from a file. Since you are accessing the api to get a json string try something like this
A working js fiddle (with another Url)
var url = 'http://localhost:57507/api/Employee/Get';
var table = $('#example').DataTable({
'processing': true,
'serverSide': true,
'ajax': {
type: 'POST',
'url': url,
'data': function(d) {
console.log(d.order);
return JSON.stringify(d);
}
},
columns: [{
data: 'Employee_Id'
}, {
data: 'Project_Id'
}, {
data: 'Grade_Id'
}, {
data: 'Site_Id'
}, {
data: 'Location_Id'
}, {
data: 'StartDate'
}, {
data: 'EndDate'
}, {
data: 'BillRate'
}, {
data: 'Role'
}, ]
});
Using this as an example how do I control the format of the values in the cells?
for example, how would I format the Extn. column to read 5,407 or 54.07?
Name Position Office Extn. Start date Salary
Airi Satou Accountant Tokyo 5407 $2008/11/28 $162,700
I have been searching here and here but I can't quite work it out. can anyone advise?
I have tried something like this, but am having no success:
$(document).ready(function() {
$('#example').DataTable( {
data: dataSet,
columns: [
{ title: "Name" },
{ title: "Position" },
{ title: "Office" },
{ title: "Extn." },
{ title: "Start date" },
{ title: "Salary" }
],
"aoColumnDefs": [ {
"aTargets": [ 4 ],
"mRender": function (data, type, full) {
//var formmatedvalue=data.replace("TEST")
//return formmatedvalue;
return '$'+ data;
}
}]
} );
} );
Use the columns.render option.
Either with the built-in helper, to get a thousand seperator (5,407):
{
title: "Extn.",
render: $.fn.dataTable.render.number(',', '.', 0, '')
},
JSFiddle example
Or do it yourself with a custom function (54.07):
{
title: "Extn.", render: function (data, type, row) {
return data / 100;
}
},

I am getting this error Cannot read property 'oFeatures' of undefined datatables I am using bubble editing of datatable editor
<script type="text/javascript">

});
</script>
I am getting this error in console, Cannot read property 'oFeatures' of undefined . I am using bubble editing for datatables.net editor.
I also get this error.
It was the issue, Editor's table property is different DataTable Id.
After use same Id, it's fixed.
